MEAN ANNUAL RUNOFF OF THE RIVERS OF THE CRIMEAN PENINSULA SOUTHWEST

The authors have studies the regularities of the mean annual runoff of the rivers at the Crimean Mountains Northwestern slopes on the basis of the hydrological stations' data. For all station, including the closed ones, that data were unified against a single manyyear uniform period for which we calculated mean annual water flows and runoff modules. It has been stated that mean annual runoff modules, in contrast with the most of small rivers of Russia are decreasing with the increase of catchment areas and the river hydrographic length, and this is associated with the evaporation effects. In addition, we have found diminishing dependence of mean many-year runoff modules on remoteness from the sea and increasing dependence on the catchment average height.We have stated that it were these above factors that decisively effect on the Kacha, Belbek, and Chernaya rivers runoff formation, particularly in the downstream were the watercourses face anthropogenic impact. These rivers have catchment areas exceeding 250 km2 . The anthropogenic factors impact upon formation of the mean annual runoff is not so significant in comparison with that for rivers with lesser catchment areas. However, any hydrological station data supporting this fact are not available.
