The Chernaya river annual flow security calculation and the Chernorechensk reservoir catchment area in Sevastopol

Abstract

Abstract On the Crimean Peninsula territory, there are 1657 permanent and temporary watercourses with a total length of 5996 km, their length, catchment areas and water volumes are small. Most (92.1%) are watercourses less than 10 km long. Particular attention is paid to the Chernaya river basin, supplying the Chernorechensk reservoir - one of the largest in the region and providing water to the city of Sevastopol Explored for the first time in the complex of the r.

Armanka, the r. Calenda. The article presents calculated data on the Chernaya river annual run-off availability and all its tributaries It was revealed that the annual run-off statistical characteristics adopted for the water stations adequately reflect the current situation in the long-term section with the river run-off of the Chernaya River and the Chernorechensk reservoir catchment area.
