Elaborate detailed technical engineering design for the necessary infrastructureimprovements, including new canals, structures <strong>and</strong> rehabilitation of existingfacilities, to ensure restoration <strong>and</strong> sustainable management of wetl<strong>and</strong>s under thecurrent hydrological regime in the <strong>Danube</strong> river.> Carry out detailed cost estimates for all infrastructure construction <strong>and</strong>improvement.> Prepare bid documents required for tendering as per World Bank st<strong>and</strong>arddocuments for the construction of the required infrastructure components> Develop an operational <strong>and</strong> maintenance manual to operate <strong>and</strong> maintain thefacilities in a sustainable mannerThe final design solution for each site needed to ensure that the restoration<strong>and</strong> sustainable management of the wetl<strong>and</strong>s could be met under the currenthydrological regime in the <strong>Danube</strong> River. These improvements should aim tomaximise the water flow through the system in order to optimize nutrient trapping,bio-diversity restoration, maximise fish production <strong>and</strong> create opportunities forfisheries development, <strong>and</strong> minimise sedimentation.Results of the project:The most important <strong>and</strong> innovative activity of the project is the physicalrestoration of the wetl<strong>and</strong>s in the two protected areas. In the course of theimplementation of this component activities the project has restored 4 035 ha offormer wetl<strong>and</strong>s on two specific sites – Belene Isl<strong>and</strong> (2 280 ha) within the PersinaNature Park <strong>and</strong> Kalimok/Brushlen (1 755 ha) within the Kalimok/Brushlen ProtectedSite – in order to demonstrate the use of riparian wetl<strong>and</strong>s as nutrient traps.In order to achieve efficient restoration of the wetl<strong>and</strong>s it is necessary toenable the <strong>Danube</strong> River water flow into the previous marsh territories. To provide forthis some engineering facilities are built, including sluices, channels, dykes to protectthe adjacent l<strong>and</strong>, as well as access roads. Thus an option for controlled flooding,optimized trapping of nutrient elements, <strong>and</strong> restoration of biodiversity <strong>and</strong> fishpopulations, living in these water basins will be ensured. All that will allow forsustainability of the wetl<strong>and</strong>s ecosystems.39
