Morphometric characteristics of the Krasnyj Klyuch lake Complex (Republic of Bashkortostan, Russia)

Abstract

The article presents the results of researching the morphometric features of the Krasnyj Klyuch lake complex, located on the Ufa Plateau in the Republic of Bashkortostan on the left bank of the Ufa River. According to available data, the largest karst spring in Russia and the second in Europe in discharge of spring wells at the bottom of the lake complex, which makes the task of researching the morphometric characteristics of the lake complex itself an important step towards researching the unique spring. To date, detailed data, reflecting the features of the relief of the lake bottom have not been available. During the research, a bathymetric survey of the lake complex was carried out from the board of a boat, using an echo sounder, combined with a navigator. The results of field research were processed using the geoinformation program QGIS, a digital model of the relief of the lake basin was created and its main morphometric characteristics were calculated. The results of the researchhave both scientific significance, allowing to detail knowledge about the morphometric characteristics of the unique lake complex Krasnyj Klyuch, and applied – being the center of gravity of recreants, the lake complex Krasnyj Klyuch requires a detailed research of morphometric parameters in order to effectively organize recreation.
