3261 Vandtillbageholdelse i vådområder: Odense Å case område Water detention through temporary flooding of wetlands can play a significant role in cutting of flow peaks, and thereby decreasing water levels and floodrisk in downstream towns and villages during incidents of extreme precipitation. Restoration of the Odense river, Denmark
3531 Vegetated ditches for treatment of surface water with highly fluctuating water regime Vegetated drainage ditches (VDD) as a type of constructed wetland primarily serve to remove and store excess water associated with irrigation and storm events. Current research suggests using a VDD as an additional practice in the mitigation of surface water pollution. The VDD for water treatment of the Glinscica River was constructed in 2006. The efficiency of the system was evaluated in 2008 and 2009 regarding the reduction of SS, COD, BOD5, NH4-N, NO3-N, NO2-N, TN, ON and TP. The microbiological association developed in the VDD was analyzed with a focus on the identification and quantification of the narG gene as a denitrification indicator. This paper discusses the efficiency of pollution removal and the distribution of the narG gene within the VDD. The results showed that the highly fluctuating water regime was the main reason for the even distribution and abundance of the narG gene throughout the system, regardless of oxygen saturation or the nutrient status of the wastewater. With the exception of SS, pollutant concentrations met the permitted outflow levels. Pollution Treatment on the Glinščica, Slovenia

3343 Wetlands Restoration - Pollution Reduction GEF Project The development objective of the Wetlands Restoration and Pollution Reduction Project for Bulgaria is that local communities and local authorities in the Persian Nature Park and Kalimok/Brushlen Protected Site areas adopt sustainable natural respurces management practices. There are two amin project components. First, in the initial phase of this component, marshland will be recovered and restored in two already identified sites to demonstrate the use of wetlands as nutrient sinks. Additional sites are expected to be identified. Wetland restoration in Persina, Bulgaria
3282 WETLIFE project's final report and deliverables The WETLIFE project aimed at reversal of negative changes in Amalva and Ž’uvintas mires. Restoration of hydrological conditions necessary for regeneration of mire habitats was the main key to reaching the aim. Additionally, the project had a goal to facilitate a shift in agricultural practices on peatlands in order to improve conditions for biodiversity and reduce rate of peat mineralization with all related environmental consequences. Finally, the project expected to raise awareness about wetlands and to serve as an example of successful wetland restoration and more sustainable use that could be replicated in other parts of the country. see also project video: Restoration of Amalvas and Žuvintas Wetlands, Lithuania
3501 WETREST - Restoration of Wetlands at Zahorie Lowland The project aimed to restore the original water conditions at the eight project sites to enhance the quality of the river and adjacent habitats. It planned to do this by restoring river banks, installing five small weirs and filling in over a kilometre of drainage ditches. Wetland restoration in the Zahorie lowland, Slovakia
