The history of the development of the hydrometric network within the basin of the Southern Bug from the end of the nineteenth century to today is considered. The Southern Bug basin is among the well-studied hydrologically, although instrumental hydrological observations on the river began later than other large Ukrainian rivers. The interest of scientists and practitioners for a long time was limited only to the study of the lower section of the river, suitable for navigation. The presence of thresholds and fluctuations along the river and its inflows, on the one hand, prevented the development of navigation, but, on the other hand, have long promoted the use of their mechanical energy. Interest in studying the hydrological regime of the Southern Bug River from the beginning of the 20th century has grown in connection with studies on the possibility of using the river for electricity generation. The distribution of operating hydrological stations over the duration of the observation period and the area of the water catchment area is analyzed. The largest duration of observations is characterized by the South Bug River in town Alexandrivka, which has a 100-year observation period. By typising the Water Framework Directive of the European Union hydrological stations of the basin, where the water discharge is measured, are located, mainly (50%) in large and very large (23%) rivers. The small rivers, where only one hydrological station operates, remains practically not covered by observations. The first generalizations of hydrological observations on the rivers of the basin were made in the mid-20th of the last century. In the post-war time, as accumulation of observations on the hydrological stations of the basin, the preconditions for their synthesis and further analysis were created. One of the first steps in obtaining practical experience in implementing the provisions of the EU WFD in Ukraine was the development of the "Southern Bug River Basin Management Plan", 2014. |
