|Wetland restoration in Ciobarciu, Romania||The short term project objectives were to create 250 ha of wetland by raising the water level of the embanked area with a regulating water outlet structure, creation of a variety of habitats -from dry land to spots with deep water- by digging and opening up of old river meanders that had been filled up.
The project is a good experience in the field of ecological restoration, involving purchase of land, participatory planning and co-operation with other organizations, including NGO’s.
The project also had long term objectives related to the creation of a network of wetlands, integration and nature and water policies, the implementation of European directives and the strengthening environmental NGOs and education. The project was implemented by a Romanian regional water authority with the support of Dutch partners.
The Ciobarciu project was evaluated at the end of the project by the project team and by a Romanian University, who interviewed 55 inhabitants of villages where the (previous) owners lived. After a period of five years, the project was evaluated again.

|Traditional terracing in Veneto, Italy||The initiative is aimed at the recovering and maintenance of a cultural and historical heritage with the promotion of new agricultural activities (not necessarily for economic purposes). A large part of terraces are no longer used today, as landowners either emigrated or are too old to take care of them. As a consequence, these terraces are increasingly degraded. The Committee "Adotta un terrazzamento" (Adopt a Terrace) acts as a mediator among landowners and people interested in "adopting" a terrace": with a contribution of 10 euros, any private citizen can be assigned a terraced plot to establish a vegetable garden. In exchange, the private citizen commits to restore and take care of the terrace at his/her disposal. The recovery of the terraces permits the valorization of the local resources, combining social/economic aims with the need to safeguard infrastructures that prevent hydro-geological instability.||http://nwrm.eu/case-study/traditional-terracing-veneto-italy||Italy_04||Veneto |
|The Vonarje flood storage reservoir in Croatia||The Sutlansko Lake area is a wetland with a high biological diversity. The Vonarje reservoir was initially built for drinking water supply and flood protection. The reservoir was drained due to difficulties encountered to manage its water quality. Now it operates as a dry retention basin for flood protection. At the bottom of the reservoir, wetland ecosystems developed. For this reason, the area of the reservoir on the Slovene side has been declared as a Natura 2000 site.||http://nwrm.eu/case-study/vonarje-flood-storage-reservoir-croatia||Croatia_03||Kontinentalna Hrvatska |

|Small Water Retention Program in Forests (lowlands) of Poland||Forest ecosystems in Poland have long suffered from drought. From the mid-90s, the Polish forest management authority undertook a variety of small-scale water retention works, financed from a combination of its own and external funds (i.e. the Polish Ecofund, and the Polish National Fund for Environmental Protection and Water Management). In 2006, the authority consolidated all its initiatives into a single project ‘Increasing retention and preventing floods and droughts in forest ecosystems in lowland.’ It is the first to be conducted on such a large scale, combining water retention in forest ecosystems with the protection against surface water run-off. The project is funded by EU Cohesion Fund, 2007-2013.||http://nwrm.eu/case-study/small-water-retention-program-forests-lowlands-poland||Poland_02|| |
|Small scale measures under the 'Waters neighborhood Days' in Hamburg, Germany||The measures implemented at two river within the city of Hamburg (Germany) included the restoration of rivers and ponds (N1), the revitalization of flowing waters (N5), natural bank stabilization (N10), and channels and rills (U5). They targeted the National Biodiversity Strategy of Germany as well as the achievement of a good ecological status as defined by the WFD. For the identification of locations for possible measures the general public was involved using online forms. The implementation was then carried out by a local chapter of the German nature conservation NGO NABU. This NWRM proves to be highly effective while easy and cheap to implement, it is therefore considered a success.||http://nwrm.eu/case-study/small-scale-measures-under-waters-neighborhood-days-hamburg-germany||Germany-02||Hamburg |
|Slowing the Flow at Pickering, UK||The Project 'Slowing the Flow at Pickering' implements multiple natural flood risk measures including low level bunds, large woody debris dams, planting riparian and floodplain woodland, planting farm woodland, blocking moorland drains and establishing no-burn buffer zones, blocking forest drains and implementing farm-scale measures. The aim of the project is to show how land management measures can help to reduce flood risk from a river in the town and is implemented in close cooperation with local stakeholders. The project involved both the Pickering Beck and adjacent River Seven catchments, the description of measures described below relate to the former.
The town of Pickering in North Yorkshire has a history of flood events, most recently in 1999, 2000, 2002 and 2007; the last of these causing an estimated £7m (€8.05m) of damage. The Slowing the Flow at Pickering project was one of three pilot projects funded by under Defra’s multi-objective flood management demonstration programme. A flood alleviation capital scheme was also proposed but deemed unaffordable under current national cost-benefit thresholds.
The main principle of the project is to achieve flood risk management using natural processes. This involves developing an understanding of how land use and management across the entire catchment contribute to flood risk. The project is also concerned with wider environmental, economic and social benefits. These include improved water quality, provision of new and/or improvement of existing habitats, enhanced carbon sequestration, enhanced local skill base in estate management, improved recreation/tourism access and increased public understanding and engagement in land management for flood risk reduction.||http://nwrm.eu/case-study/slowing-flow-pickering-uk||UK_03||North Yorkshire |
|Sediment capture ponds in the Latvian State forests||During last years the construction of the sediment capture ponds as a part of the drainage system has become a good practice measure in the forests managed by Latvian State Forests, therefore some of the environmental impacts of this measures has been monitored to justify its costs. The results indicate differences between monitoring sites set up on mineral or peatland soils as well as between different measured parameters. Additionally, it seems that the effectiveness of the measure depends on the skills and quality of the work carried out by professionals constructing the ponds.||http://nwrm.eu/case-study/sediment-capture-ponds-latvian-state-forests||Latvia_02||Latvija |
|Rural runoff attenuation in the Belford catchment, UK||Measures to attenuate runoff were installed in the small Belford catchment, in northeast England, in order to reduce the risk of flooding to the village downstream. The installations involved a network of small measures to capture and delay runoff from the rural catchment, including detention basins and overland flow features, as well as sediment capture measures to improve water quality.||http://nwrm.eu/case-study/rural-runoff-attenuation-belford-catchment-uk||United Kingdom_01||Northumberland and Tyne and Wear |
|Room for the River: Nijmegen dike relocation, Netherlands||This example is one of many schemes being implemented through the national 'Room for the River' programme in the Netherlands. This particular measure involves setting back the dyke of the River Waal, and incorporating a new channel in to the expanded area of floodplain that can take additional flood flow from the Waal. The measures are also incorporated with a new area of urban development and will create an urban river park within the city of Nijmegen.
|River Tolka constructed wetland and enhancements, Ireland||The River Tolka runs through Dublin, Ireland. A series of measures was applied to the urban sections of the river to slow flood flows, reduce pollution and support wildlife. These included the establishment of retention ponds to manage runoff storage; bank engineering to slow flows and prevent erosion; and planting trees along the river to slow runoff. Two phases of retention pond construction have been carried out, the latter as part of a wider ‘Greenway’ project to develop a green corridor with cycling route.||http://nwrm.eu/case-study/river-tolka-constructed-wetland-and-enhancements-ireland||Ireland_001||Southern and Eastern |
|River restoration of the lower Aurino in Italy||This case study focuses on the restoration of the Aurino stream. River restoration measures were implemented along the Aurino stream as part of the Aurino management plan. Interventions were implemented in different moments within the years 2003-2011. The objectives were flood protection and, secondarily, the improvement of the natural environment. Different interventions were implemented to widen the river bed, such as for example: (i) forests were cleared in the relevant areas, to add space to the river bed; (ii) (artificial) river banks were lowered and enlarged; (iii) re-activation or creation of lateral river branches; (iv) measures to raise the river bed’s level. The Autonomous Province of Bozen – Hydraulic engineering department was in charge of funding, planning, designing and implementing the measures.
Before implementation, all measures were extensively presented to, and discussed with, municipalities, farmers, fishermen associations and local communities; informing and involving local communities and key stakeholders was the key to successful implementation. The availability of land was the main constraining factor: most of the measures were implemented on public land (state or municipal land). Only in the case of Gatzauer/ Gais Lot III measures were implemented mostly on private land, but this required compensation.
When implementing these NWRM, interventions had to seek a balance between the desired outcome and the economic activities in the area of intervention. In this case, for example, bringing back the ground water level back to the original level would not have been a desirable outcome for farmers. Negotiations with farmers led, on the one hand, to a reduced ambition of the interventions, but on the other hand it also led to acceptance of the measures and, ultimately, contributed to the success of implementation.||http://nwrm.eu/case-study/river-restoration-lower-aurino-italy||Italy_01||Provincia Autonoma di Bolzano/Bozen |

|Retention pond in Chêne Bougerie, Switzerland||This case study is located in Switzerland, in the city of Chênes Bourgerie. It presents one of the natural water retention measures that can be implemented in urban areas to reduce runoff and flood risks. A retention pond is implemented on a plot to retain about 450m3 of water, which contribute to retain water at the watershed scale (279m3 for 3,1ha). The pond also provides a "natural" area which can be used as recreative area for neighboring private owners and contributes to reduce mosquitos density.||http://nwrm.eu/case-study/retention-pond-ch%C3%AAne-bougerie-switzerland||Switzerland_03||Ticino |
|Restructuring the effluent web in Italy||The case study is located in the draining basin of the Venice Lagoon. It is characterized by intensive agriculture and by a web of drainage channels discharging into the rivers. This case study, in particular, includes measures on the drainage channels discharging into the Dese river, one of the main water bodies of the Venice Lagoon basin.
The Veneto Region, through the “Plan for diffuse pollution prevention and restoration of water in the draining basins of the Venice Lagoon” financed measures of re-calibration of riverbeds aimed at the renaturation of the hydraulic web, to increase the time of permanence of water and phytodepuration processes in the draining basin. In this framework, the Consorzio Acque Risorgive implemented a series of extended interventions on the area under its responsibility. This case study was implemented as part of these interventions.
In particular, it aimed at re-structuring the effluents of the mid course of the Dese river (Rio S. Martino, Rio S. Ambrogio and Scolo Desolino). Such effluents are mostly draining channels, draining water from agricultural fields to the Dese river. The primary objective was the reduction of the amount of N and P reaching the Venice lagoon through phytodepuration. However, at the same time the project carried out the restoration of the draining channel web aimed at reducing flooding issues affecting the area. Over the years, the area has in fact been subject to massive urban development (new residential and industrial areas), with consequent soil sealing and culverted effluents: this had a devastating effect on the hydrological system. The strong floods of 2006 and 2007 on the city of Mestre, for example, were a consequence of this.
The following measures were implemented: (i) Riparian buffer zones; (ii) Creation of wetlands; (iii) River bed enlargement; (iv) Creation and reconnection of floodplain and new buffer strips; and (v) Channel naturalization, creation of new meandering channel.
The ability of the measures to address two pressing environmental issues in the area was a key success factor. The measures proved in fact very effective in reducing nitrogen loads in effluents and, ultimately, into the Venice Lagoon, as well as mitigating flood risk in the area. During the implementation phase, some residents complained for the annoyance (e.g. the dust lifted by the machinery). However, during the first intense precipitation, the rivers/ channels did not overflow (they would have before implementation), so residents understood the key role of measures for flood mitigation. Furthermore, the overall decrease of N levels in the Venice lagoon, which followed the implementation of these and other similar measures in several sites within the draining basin, contributed to gain a positive public perception of these measures.||http://nwrm.eu/case-study/restructuring-effluent-web-italy||Italy_02||Veneto |
|Restoring the River Quaggy in London, UK||River restoration and flood management measures were implemented on the River Quaggy in London. The measures were necessary due to increasing urban development in the river valley and natural flood plain, with an associated increase in fluvial flooding. A suite of measures was implemented between 1990 and 2005, including de-culverting a reach of river and creating associated floodplain; building a detention basin; set-back flood defences; channel re-profiling. This scheme took a catchment-scale view in order to develop the best solution, and worked with a multi-disciplinary team as well as having extensive community involvement.||http://nwrm.eu/case-study/restoring-river-quaggy-london-uk||United Kingdom_02||Inner London |

|Restoration of Wetlands in the Western Lowland Area of the Dümmer Lake, Germany||This Project combined several natural water retention measures: the restoration of meadows and pastures (A1), reduced tillage (A7), a reduced stocking density (A12), and the restoration of wetlands (N2). The project area was located in north-west Germany within the river basin district Weser (DE4000). As funded under the LIFE Program, it was directed at European policy contexts, namely the WFD, Habitats Directive, and Birds Directive. A wide variety of stakeholders was involved in the implementation process, ranging from nature conservation agencies and NGO’s, as well as water managers to local farmers. The project achieved an increase of the population of meadow birds in the area, and was therefore successful. Furthermore, the constructive exchange of interests and opinions, leading to common benefits for different stakeholders has to be considered an additional success. ||http://nwrm.eu/case-study/restoration-wetlands-western-lowland-area-d%C3%BCmmer-lake-germany||Germany_03||Hannover |

|Restoration of the Odense river, Denmark||The Odense is a river in southern Denmark. It was channelized and deepened in the late 1940s to improve agriculture. The NWRM consists of a series of measures to restore floodplain connectivity along a 17 km section of the river. The measures will prevent flooding in downstream towns and cities. This will have a number of effects on the pressures relevant for the WFD. Reduced risk for flooding of urban environment reduces the risk for storm overflows from sewers as well as diffuse pollution resulting from flooding in general. Re-meandering reduces the pressure from previous physical alterations for flood protection and agricultural purposes. It will also potentially have a positive effect on ground water recharge in temporarily flooded areas.
|Restoration of the Ernz Blanche river, Luxemburg||The Ernz Blanche (Luxembourg) river restoration project aimed at erasing the effect of the river chanelling, which caused the river uniformisation and floods downstream. The project consisted in a remeandering, increase of the base level of the river and widening of the riverbed.||http://nwrm.eu/case-study/restoration-ernz-blanche-river-luxemburg||Luxembourg_2||Luxembourg |
|Restoration of the Cerny Potok stream, Czech-Republic||The Nature Conservation Agency of the Czech Republic carried out the retoration of Cerny Potok stream which was based on common principles of stream restoration. The main aim of the restoration was to decrease the volume of the restored stream-beds especially by reducing their depth. Modifications within the channelized stream-bed were not sufficient, therefore new stream-beds were proposed and constructed. They were reconnected with the remains of the original stream course or directed freely to the alluvial meadows.
|Restoration of river Hermance, France||Hermance is a French/swiss transboundary river. From 2006, in the frame of a transboundary river management program, the SYMASOL has been implementing restoration measures along river in order to decrease flood risk downstream, supported amongst other by Geneva Canton. The river mouth have been widenned, the river has been remeandered, 2,3km of the river have been renaturated and vegetation have been planted back on banks. The Mermes marshland water retention power has been exploited through the creation of a retention pond. In addition to flood risk reduction for a hundred houses, the renaturation and restoration of a path along the river provided social benefits: people happen to appropriate again their river.||http://nwrm.eu/case-study/restoration-river-hermance-france||France_02||Rhône-Alpes |

|Restoration of raised bog Aklais in Latvia||The main goal of the implemented NWRM was to restore natural hydrological regime in drained raised bog Aklais located in nature reserve area being also the Natura 2000 site in Latvia. Building of the dam was chosen as most appropriate method. Due to natural conditions, there was no possibility to use technique thus dams were built by hand. Unfortunately the part of the dams is partly washed out by waters now and in a result raised bog is not restored as expected. The main lesson for future is to use adequate technique and materials to ensure durability of the dams.||http://nwrm.eu/case-study/restoration-raised-bog-aklais-latvia||Latvia_03||Latvija |

|Restoration of Durrow floodplain alluvial woodland, Ireland||This site was one of nine included in the LIFE05 project to restore priority woodland habitats in Ireland. The Durrow site is located on the floodplain of the river Erkina, and had been affected by planting of non-native conifers and associated drainage. A network of shallow drainage ditches covered the entire site, and was found to be adversely affecting the native alluvial woodland by reducing retention time of floodwaters on the floodplain. To counter this, a total of 350 dams were installed on ditches across the site.||http://nwrm.eu/case-study/restoration-durrow-floodplain-alluvial-woodland-ireland||Ireland_02||Southern and Eastern |
|Restoration of Coastal Meadows in Matsalu, Estonia||The measure was implemented in Matsalu National Park, Estonia, a former coastal meadow site (Natura 2000 and Ramsar site) next to a big Salmi coastal meadow with many priority species. The old non-functioning small ditches were closed and scraped to restore the wetland hydrology and breeding and feeding grounds for waders and amphibians. Before the restoration works the area was used mainly for bovine grazing and the restoration did not change the conditions for that. However, due to the activities drinking water will be better available for the cattle. The project was implemented in 2013.||http://nwrm.eu/case-study/restoration-coastal-meadows-matsalu-estonia||Estonia_01||Eesti |

|Habitat Reconstruction in the forests of the Körös Valley, Hungary||The fragments of floodplain forests (Fraxino - pannonicae -Ulmetum) along the River Körös were cut from the river by dykes during the river regulation works in the 19th century. The deteriorated groundwater conditions were worsened in a drought period during the 1980-1990’s that triggered action of the forestry service. Restoration of the river connection and the floodplain watercourse network provide surface water supply from the backwater of flood waves to the 2000 ha forest. The result of the habitat reconstruction work is a 38.8 km long water-flow and a water surface of 15.7 hectares, cc 400 hectares of the forest has a direct positive ecological impact.
The water supply of the floodplain channel network has another source as well. A smaller volume comes from a fishery. In case of this second source the nutrient content of the fishery is assimilated in the forest as an additional service.

|Exmoor Mires peatland restoration, UK||The Exmoor Mires project is part of a wider Upstream Thinking programme initiated by the local water company South West Water (SWW) to use land management to tackle problems of water quality and quantity across South-west England. The benefit to SWW is in potentially reducing the costs of water treatment. Demonstration of success will allow SWW to approach the regulator (OFWAT) for permission to develop PES schemes to deliver these benefits in future. The Exmoor Mires project involves peatland restoration through blocking historic drainage ditches with a target of restoring 2000 ha by 2015. The primary benefits of the project have been to reduce runoff (32%) and increase water storage (additional 364 m3/ha). The success of the project has been aided by the land ownership and public engagement by the Exmoor National Park Authority and support from other public agencies and research from universities.||http://nwrm.eu/case-study/exmoor-mires-peatland-restoration-uk||UK_04||Dorset and Somerset |

|Ecological adapted stormwater treatment in Kretinga town, Lithuania||Kretinga is located 12 km east of the popular Baltic Sea resort town of Palanga, and about 25 km north of Lithuania's 3rd largest city and principal seaport, Klaipėda. The Stormwater Special Plan developed introduces a new approach towards more sustainable stormwater solution from an environmental perspective. This type of ecologically adapted stormwater investments have been implemented in Lithuania for the first time. If they function as well as predicted and can be disseminated through appropriate channels, there should be good possibilities to introduce similar investments in other Lithuanian towns.||http://nwrm.eu/case-study/ecological-adapted-stormwater-treatment-kretinga-town-lithuania||Lithuania_02||Lietuva |
|Dyke relocation on the river Elbe near Lenzen, Germany||In the framework of the large-scale nature conservation project "Lenzener Elbtalaue", a dyke along the river Elbe (in Germany) has been relocated. This created a new retention area with a diverse floodplain, including alluvial forests, half-open pasture landscapes and other typical habitats of lowland floodplains. With 420 ha it is the biggest application of this type of measure in Germany so far. The project successfully combines flood protection and nature conservation objectives.

|Climate-Proofing Social Housing Landscapes||Groundwork London, in partnership with Hammersmith and Fulham Council, received LIFE+ funding for the Climate-Proofing Social Housing Landscapes project in 2013. The project, which came to an end in September 2016, has demonstrated an integrated approach to climate adaptation in urban areas by undertaking a package of affordable, light-engineering climate change adaptation measures based around the retrofitting of blue and green infrastructure (tsee illustrations in herewith file). Alongside this, the project has also featured in-depth community engagement and awareness-raising of climate change adaptation opportunities, as well as training local apprentices and local authority staff in the skills to implement and maintain such measures.
These measures have been implemented in three different social housing contexts in West London, within areas characterised by high levels of multiple deprivation including higher exposure to climate-related risks. Ultimately, the project aimed to demonstrate an integrated approach to addressing climate-related and wider socio-economic challenges in vulnerable urban environments.||http://nwrm.eu/case-study/climate-proofing-social-housing-landscapes||United Kingdom_06||Inner London |
|Barking Riverside Green Roof Ecomimicry Experiment||Conserving important brownfield invertebrate community of regional importance as part of strategic multifunctional green infrastructure. Target species included the brown-banded carder bee (Bombus humilis) (UK Biodiversity Action Plan Priority Species) and Gymnosoma nitens (RDB1) but also a wider set of species. This project used an innovative ecomimicry approach to designing urban green infrastructure for the new development. Ecomimicry involves mimicking the characteristics of local ecosystems, in this case regionally important open mosaic habitat which had formed on the post-industrial brownfield site.
Designing green roofs using ecomimicry of key brownfield habitat niches provided a mechanism for conserving the biodiversity, habitat connectivity and ecosystem service provision of the brownfield site post-development. This approach also offered opportunities for local communities to reconnect with nature, and the industrial heritage of the site, promoting engagement, ownership and enjoyment.
Novel green roof designs were developed and tested on site and were successful in supporting the regionally important biodiversity associated with the site prior to development. The results are being fed into innovative green infrastructure design that will be rolled out more broadly across the site as wider redevelopment continues. Embedding regional context into green roof design enabled alleviation of location-specific issues caused by urbanisation of the site and allowed restoration of regionally typical and important habitat and ecosystems. It is hoped that such design will enable Barking Riverside site to act as stepping stone habitat (Saura et al., 2014), providing connectivity between key sites that are being conserved and protected in the region||http://nwrm.eu/case-study/barking-riverside-green-roof-ecomimicry-experiment||UK_7||Outer London |
|Baixo Vouga Lagunar (BVL) bocage landscape, Portugal||Baixo Vouga Lagunar (BVL) bocage landscape (Portugal)
This is a traditional practice in the Baixo Vouga Lagunar Area (Aveiro District, Vouga River Estuary, Portugal), since 19th century in order to protect BVL from the tidal floods. Baixo Vouga Lagunar represents a man-shaped landscape working in a dependent relationship between agricultural activities, wildlife and water regulation. BVL includes three main landscape units: bocage (smallholdings bounded by living-hedges and water ditches supplying water for crop and livestock production and also assure the drainage when there is water in excess in the fields), wetlands and open-fields.

Additionally, the reconnected polder enable reed harvesting, grazing, fishing and ecotourism.||http://nwrm.eu/case-study/babina-restoration-project-romania||Romania_02||Sud-Est |
|Aquifer recharge in Malta||Aquifer recharge with highly polished treated effluents.
With a high population density and almost inexistent surface waters, Malta is in a situation of over abstraction of its groundwater resources and where its total water demand exceeds the sustainable yield of the naturally renewable freshwater resources. Demand comes from the domestic and agricultural sectors alike (the domestic use can even exceed the agricultural use with the arrival of tourists during touristic seasons). From a qualitative point of view, freshwater resources are also under threat resulting from nitrates and salt water intrusions.||http://nwrm.eu/case-study/aquifer-recharge-malta||Malta_01||Malta |
|Alzette river restoration in the "Am Brill" nature reserve, Luxembourg||The Alzette river (Luxembourg) restoration project aimed at erasing the effect of the river chanelling, which caused the river uniformisation and an ecological impoverishment. The project consisted in a remeandering, increase of the base level of the river, widening of the riverbed, reconnection of the river to existing ponds and creation of a new pond. ||http://nwrm.eu/case-study/alzette-river-restoration-am-brill-nature-reserve-luxembourg||Lux_03||Luxembourg |
|Alzette river restoration in Dumonshaff, Luxembourg||In the 50's and 60’s, the alluvial plain of the Alzette river was deeply modified in order to develop intensive agriculture. As a result, the water retention was reduced and ecological value declined. The project aimed at restoring the ecological state of the Alzette in Drumontshaff (Luxembourg). The two mains tasks of the project were to restore the natural functioning of the Alzette river (frequent overflowing and flooding of aside land, wetland habitats restoration) and to develop an extensive management of aside meadows (late mowing, no fertilizer or biocidal product, etc.).
The first step was to determine the floodplain through past and current reference values. After the feasibility study, a reallocation scheme was drown. An agronomic feasibility study was made to determine socio-economic solutions. The river and hydraulic annexes were restored (lateral enlargement or displacement of the river bed into natural thalweg). Finally, the restoration of the complete flood plain was possible.||http://nwrm.eu/case-study/alzette-river-restoration-dumonshaff-luxembourg||Luxembourg_01||Luxembourg |
