Nid Title Abstract Case study
3478 Attenuation capacity of a coastal aquifer under managed recharge by reclaimed wastewater Managed Aquifer Recharge (MAR) is becoming an increasingly attractive water management option, especially in semiarid areas. Nevertheless, field studies on the fate and transport of priority substances, heavy metals and pharmaceutical products within the recharged aquifer are rare. Based on the above, the objective of this project is to study the hydrological conditions of the coastal aquifer of Ezousa (Cyprus) and its ability to attenuate pollutants. The Ezousa riverbed is a locally important aquifer used for a MAR project where treated effluent from the Paphos Waste Water Treatment Plant is recharged into the aquifer through a number of artificial ponds along the riverbed. Additionally, groundwater is pumped for irrigation purposes from wells located nearby. The hydrological conditions of the area are unique due to the construction of the Kannaviou dam in 2005 that reduced natural recharge of the Ezousa aquifer significantly, inducing the saltwater intrusion phenomenon. A three-dimensional finite element model of the area was constructed using the FEFLOW software to simulate the groundwater flow conditions and transport of Phosphorous and cooper in the subsurface from the recharge process. The model was calibrated using hydraulic head and chemical data for the time period of 2002-2011. The groundwater model was coupled with a geochemical model PHREEQC attempting to evaluate nitrate and Copper processes. Inverse modeling calculation was used to determine sets of moles transfers of phases that are attributed to the water composition change in groundwater between the mixture of natural groundwater and reclaimed wastewater and the final water composition. © (2013) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).

3216 Benchmarking river habitat improvement. River ecosystems have witnessed a long history of human pressure, particularly the disruption of freshwater fish populations. The awareness of this situation has led to many habitat improvement projects, with a variable degree of success. In natural situations, fish populations co-inhabit throughout the hydrological cycle with different degrees of adequacy, and the sequence of favourable and unfavourable conditions dictates abiotic constraints and biotic interactions that shape the final biological assemblages. We postulate that a part of unsuccessful restoration results is related to insufficient closeness to the natural habitat conditions of the river type that is to be restored, including the naturally adverse periods.

3345 BIOMURA - Conservation of biodiversity of the Mura river in Slovenia The bed of the river Mura that flows through NE Slovenia is well preserved, especially in the middle and lower stream, where it is characterised by embankment erosion, deposition of the sand, flooding and side-channels. Deepening of the riverbed due to send accumulation behind the dams of hydropower stations in Austria, however, has resulted in a greater risk of flooding. There are no dams on Slovenian river section, but plans to alter this situation are resurfacing. Conservation of Mura banks, Slovenia

3342 Bulgaria: Wetland Restoration and Pollution Reduction Project - component of Danube/Black Sea Strategic Partnership: Nutrient Reduction Investment Fund Strengthening and rehabilitation of the dykes, which were open, and huge inlet structures (sluices) were built to ensure controlled water flow from the river to the wetlands. Adjacent arable lands are protected by intermediate dykes and drainage canals with drain pumping station. Accumulated sediments in the drainage canals were systematically cleaned up.

3346 Case study: Biomura LIFE06NAT/SI/000066 The Lippenbroek Regulated Tidal Exchange (RTE) scheme is a pilot scheme for the so-called controlled reduced tide (CRT) concept which Belgian authorities are planning to apply to (sections of) numerous flood storage areas in the near future to create tidal habitats (e.g. at Kruibeke, where the first inundation will likely occur in 2011). The CRT concept involves the use of two exchange mediums, one high inlet medium (e.g. a weir/spillway or sluice/culvert), and a lower outlet medium, which may be capped with a gravity controlled sluice gate.

3494 Case study:The Babina Restoration Project Until the 20th century vast areas of the Danube Delta faced only minimal human impacts through extensive fishery and reed harvesting. Since then the Danube Delta has undergone multiple human impacts like embankment, channelization and drainage. Moreover, large areas were diked and the polders used for agriculture. The Babina polder (2.100 ha) was reconnected to the Danube in 1994 and recovery has been monitored by the Danube Delta National Institute for Research and Development. Within a few years a redevelopment of the site-specific biodiversity occurred and ecosystem services like nutrient retention and fish recruitment became obvious. Additionally, the reconnected polder enable reed harvesting, grazing, fishing and ecotourism. Babina Restoration Project, Romania
