Improved management of shared water resources in the upper Pripyat basin (ENVSEC 000 62859) The project is looking for a practical solution for cross-border management water flow in the upper Pripyat between Ukraine and Belarus. The countries have been unable to find a mutually acceptable solution to the existing problems of water allocation on their own, whereas the existing mechanisms of cooperation failed to fully address it as well. A successful solution will both eliminate a source of potential disagreement over the use of water resources of the Pripyat basin, and strengthen the culture of a cross-border dialogue over similar cases between the involved countries.
Dniepro-Bug Canal (DBC) Republic of Belarus Beloozerskaya water feed system of DBC Ukraine The part of water flow from Ukrainian Upper Pripyat is discharging through Vyzhevskiyi floodgate, for water feeding of Dnepro-Bug Canal (DBC), which is situated at the territory of the Republic of Belarus, as a result in low-water seasons Upper Pripyat could have the deficit of water to satisfy good ecological state of natural water body. On the another hand the pass of flood water of Upper Pripyat thought Vyzhevskiyi floodgate for reducing flood areas at the territory of Ukraine, have a negative influence upon technical state of Dnepro-Bug constructions, environment in the Republic of Belarus by way of flooding. Therefore the problem of water regime management of Upper Pripyat is a transboundary problem.
Project goals The objective of the project is to support sustainable management of shared water resources in the upper Pripyat basin. This will be done through developing, adopting, agreeing Operation Rules Beloozerskaya water-feed system of the Dniepro-Bug Canal BY UA
For achievement of the goal, the joint belarussian-ukrainian complex hydrological and hydroecological investigations of Upper Pripyat and Beloozerskaya water feed system of DBC were organized and carried out (in Summer 2008 and in Spring 2009), water-balance calculations and anthropogenic assessment for different hydrological conditions and different operating modes of Vyzhevskiyi floodgate were carried out.

Recommendations on flow distribution of the Pripyat River in Verchnepripjatsky waterworks facility were suggested on the base of the minimum feasible discharge (MFD) which can provide the environmental functioning of the river and flow forming discharge. River Pripyat upstream of BWFS of DBC On the hydrological feasibilities MFD constituted 1.0 m3/sec, according to the hydraulic feasibilities on the required conditions of the flowage MFD constitutes 1.7 m3/sec, flow forming discharge constitutes 6.0 m3/sec. MFD=1.0 m3/sec and MFD=1.7 m3/sec are represented in the Recommendations. River Pripyat downstream of BWFS

Beloozersky Canal Flooded zones of the territory were developed the water levels of Beloe Lake are 146,5 - 147,6 m Beloe Lake Khabarishensky Canal Volyanskoe Lake Svyatoe Lake Vyzhevsky Canal
The recommended range of water levels change in the Lakes of Beloozerskaya water feed system is 0.4 m (from 146.8 – 147.2 m of Beloe Lake). The range is defined on the grounds of projects cameral activities using digital relief model, field hydrological Investigations and water balance calculations. Flooded zones of the territory the water levels of Beloe Lake are 146,8 - 147,2 m ∆S=109.35 hectares ∆V=4.15 million m3
