Abstract (English):
The purpose of the study is to study the bottom relief according to bathymetric survey data and calculate some morphometric characteristics of the reclamation pond. It is noted that the study, monitoring and protection at the legislative level of small aquatic ecosystems is now of particular importance. To obtain reliable and complete data on the current technical and environmental condition of such a reclamation facility, it is necessary to conduct comprehensive studies in the monitoring mode, including operational ones using Earth remote sensing technology. The possibility of using geographic information systems to solve the problems of bathymetric monitoring and assessment of morphometric indicators of water bodies is shown. The study was performed using the tools of the QGIS and SAGA GIS geographic information systems, as well as satellite images of the Landsat/Copernicus family. The maximum depth of the pond was 4.9 m, the average depth was 1.8 m. The area of the water body mirror according to the obtained water cut is 0.213 km2. The shallow zone of the pond accounted for 17% of the total mirror area.
