Synthesis documents
In order to provide information on key questions linked to the implementation of Natural Water Retention Measures (NWRMs), the following Synthesis Documents (SD) have been developed.
Environment for Europeans n°51: Moving from grey to green infrastruct
On p4 "Moving from grey to green infrastructure": this interesting article summarises some key aspects of the new approach of the EC towards Green infrastructures.You will find some further references to more detailed documents in this news article hereunder.
Second Western Regional Workshop - Save the date!
The second Western Regional Workshop will be held on July 1-2 in Strasbourg, France. Presentations, discussions and interactive sessions will focus on a key question concerning NWRM implementation: how can catchment management be adapted to widen the potential of NWRMs?More details, as well as the draft agenda of the workshop, are provided in the attached file.If you are interested in participating, please send an email to: g.depaoli@acteon-environment.euWe are looking forward to hearing from you!The Western Regional Network team
4th International Congress of Integrated Management in Upstream Watersheds
Considering that the mountain ranges are the water towers of our planet, the mountaineers, in cooperation with the large population centers of Piedmont, are rallying together to adopt adaptation strategies in response to global change that is taking place, and to prevent the risks of droughts and floods. Elected officials, water managers and scientists are invited to meet together to share ideas, debate and promote joint management of the water, at the lever of upper basins.

Afforestation
Afforestation is the process of planting trees, either to replace those removed during forest harvesting or as a means of land use conversion. Afforestation is part of several natural water retention measures as it can contribute to a more natural and sustainable hydrologic cycle.
Agricultural practice
Agronomic practices which have the primary purpose of improvements to agriculture can, in some cases, contribute to the functioning of natural water retention measures. As such, they integrate sustainable and natural water management into current practices.
Appropriate design of roads and stream crossings
Appropriately designed roads and stream crossings can minimize the likelihood of erosion and sediment production that can be associated with forestry activities including final harvest. Poorly designed or built roads and stream crossings can cause some of the most negative effects of forestry on the landscape. Well-designed roads follow the contours of the landscape. Roads which run up and down (instead of across) hills can act as channels which focus runoff and can lead to increased erosion. Properly designed stream crossings permit the free movement of fish and aquatic invertebrates and will not restrict peak flows. Ensuring that stream crossings do not restrict peak flows will help to reduce localized flooding and can ultimately be more cost effective as they will not need to be rebuilt following high flow events - Based on Stella definitions, adapted by NWRM project experts and validated by the European Commission
Artificial groundwater recharge (AGR)
AGR stores large quantities of water in underground aquifers to increase the quantity of groundwater in times of shortage.ᅠ It results in a lowering of run-off from surrounding land, and in an enhanced natural condition of aquifers and water availability.ᅠ The natural cleaning process of water percolating through the soils when entering the AGR improves water quality. Mechanisms used to undertake the recharge should be highlighted. In this respect one can envisage:(i) surface structures to facilitate/augment recharge (such as soakways and infiltration basins);(ii) subsurface indirect recharge - artificial recharge is undertaken through wells drilled within the unsaturated zone;(iii) subsurface direct recharge - artificial recharge is undertaken through wells reaching the saturated zone. The regulatory approach to be adopted for each of the above three mechanisms could differ considerably, due to the fact that the level of natural protection to groundwater is vastly different for each of the mechanisms
