Project summary

Edit project overview to modify the project summary.


WWF together with local people from Mindya village in the region of Veliko Turnovo, restored the connection of Veselina River, a tributary of Yantra, with its former meander near the village. When the river meander was cut off back in time, the river dug nearly 150 cm deeper into its bed, so now a threshold had to be built to raise its level enough for enabling it run back to its old bed. The project objective is by conducting a number of technical, environmental and forest management activities to achieve ecosystem restoration of the river Vesselina in particular: • Conservation and restoration of biodiversity in isolated old bed of the river and correction of Vesselina river near by Mindya village; • Create favorable conditions for development of recreation and tourism in the region; • Reduce the level of flood risk; • Optimization of groundwater level and reduce the impact of drought and floods on agricultural land in river terrace; • Reduction of erosion; • Increased self-purification capacity of water flow in the region of isolated old bed of the river.
