The purpose of the scientific research is the development, improvement and implementation of information technologies for a comprehensive assessment of the intensity and nature of anthropogenic pressure on urban (urbanized) water resources by contact and remote methods to improve the efficiency of the environmental management system and the environmental safety of the water fund of cities. The tasks for conducting research carried out using technologies for remote sensing of the Earth from space (ERS), specialized geographic information systems (GIS) and the results of ground-based research. The paper presents a comprehensive methodology for assessing the ecological status of the urban aquatic environment on the basis of remote sensing materials. The methodology included the following stages: at first bathymetric measurements were made in combination with remote sensing data to obtain a depth map. At the second stage of the research, we analyzed the interrelation of all received characteristics of a condition of a reservoir. For bathymetric studies, a modern hydroacoustic method is used, which consists of sonar sounding with synchronous GPS-binding of sonar profiles. Based on the results of the survey, cartographic models of the lake bottom are synthesized, bathymetric schemes and hypsometric models are created. These studies are necessary for solving problems of urban nature management, accounting, planning, forecasting, regulation, assessment of the state of urbanized aquatic ecosystems.
