Оцінка гідрографічної мережі району річкового басейну Вісли (Західного Бугу та Сяну) на території України згідно типології Водної рамкової директиви ЄС
Виконано гідрографічний аналіз за водозбірною площею річок та озер басейну Західного Бугу, річок - басейну Сану згідно типології Водної рамкової директиви Європейського Союзу. Показано наявність у басейні Західного Бугу: річок - 1 - дуже велика, 4 - великі, 30- середні; озера - 2 - великі, 9 - середні, 9 - малі, 48 - дуже малі. У басейні Сяну: річки - 1 - дуже велика; 2- великі; 9 - середні; озера - 32 - всі дуже малі.

The signing of the Association Agreement between Ukraine and the European Union (EU) provides the implementation of European standards and norms in the different economic sectors and fields of activity in our country. The EU Water Framework Directive (WFD) is the main document in the area of water relations in the European Union among a number of water conservation directives. In the WFD emphasis on integrated water resourc&es management by basin principle. With the participation of authors in 2013 was developed a method and performed modern hydrographic and water management delineation of territory of Ukraine. Under the proposed hydrographic delineation and according t&o the requirements of Water Framework Directive (WFD) in the Ukraine distinguish 9 river basins districts: the Vistula (Western Bug and San); Danube; Dniester; Southern Bug; Dnieper; rivers of the Black Sea; Don; Azov rivers; Crimea rivers. The area &of the Vistula river basin (Western Bug and San rivers) are cross-border, covers the territory of three countries - Ukraine, Poland and Belarus. The result of this study is testing the river typology on the catchment area and lakes on the area of wat&er surface under the Water Framework Directive of the European Union to assess the hydrographic network of the Vistula river basin (Western Bug and San) in Ukraine. The analysis of the basin river network showed that from the total number of river in& the Vistula basin in Ukraine (total 3115 rivers) small river represent 98.5% (according to the typology WFD). The vast majority of them - 2999 of 3068 or 97.8% - are rivers with a length not exceeding 10 km. The average rivers in the basin are only &1.25%. The share of large and very large rivers of the total number of river, respectively, 0.2 and 0.05%. In the basin of the Western Bug in Ukraine: the large river - Poltva, Rata, Luga, Ryta; very large -Western Bug. In the basin of the San in Ukr&aine: the large river - Vyshnia, Zavadivka (Liubachivka); very large - San. Of the 68 lakes that are within the Ukrainian part of the basin of the Western Bug, the vast majority (48 lakes or 70.6%) is classified as very low. Small and average lakes a&re 9 (13.3% of the total number), there are two large lakes (Svitiaz and Pulemetske) - 3.0%. All natural lakes within the Ukrainian part of the basin San are classified as very small, with area less than 0.5 km2.
