Assessment of the Kuybyshev Reservoir bed state: A case study

Abstract

The generalized results of the Kuybyshev Reservoir bed relief survey using modern methods are presented on the example of two sites. Sakony site area is located on the low left bank of the Kuybyshev Reservoir in the place of sand and gravel mix extraction, Sviyazhsk site - around the cultural heritage object Sviyazhsk island-town. The change in the bottom topography was monitored using the Interferometric Side-Scan Sonar and the HyScan software. Bathymetric maps and transverse profiles for study sites were built. A description of the bottom relief in the studied areas is given. As a result, reservoir bottom survey technique was developed to update its morphometry, possibility of obtained data application is discussed.
