Actual condition and hypsometry of the south-western coast of the Kremenchuk reservoir

Abstract

Summary The territory of the south-western coast of the Kremenchuk reservoir (100.1 km long) is under the administrative subordination of the Velykoandrusivska territorial community of the Svitlovodsk district of the Kirovohrad region (Ukraine). This part of the reservoir is characterized by a marine type of regime, with large waves and storms causing destructive effects on the coast. The research included field observations and analysis of interactive Google Earth Pro maps with GPS navigation support. It is established that the width of zone of the coastal wave surf varies from 0 m (steep shores) to 36 m. In places, bluffs with a slope of up to 90 degrees were formed. A hypsometric profile was laid along the coast of the reservoir with a length of 4.62 km – along the route of the upper edge of the coast, which limits the strip of degraded shores. With the available water level in the 77 m reservoir, the elevations of the upper edge of the coast vary from 79 m to 112 m. At the same time, the steepness of the relief along the route of the route in some places reaches 20–26% and even 35.8%. It is recommended to resume systematic monitoring of the banks of the Kremenchuk reservoir at the state and local levels, using remote sensing technologies and geographic information systems.
