Problem of hydrological research is conditioned by significant part of water reservoirs in landscape space of Ukraine. Nowadays there is an intensified natural and anthropogenic transformation in the local and regional levels of landscape. The problem that have scientific and economic significance is complex environmental assessment with creating of composite ecological indicators and research of hydrological ecosystems regularity. It this paper authors have determined regularities of the anthropogenic impact to ecological situation in the freshwater reservoirs of Ukraine. Also there were developed such scientific approaches as remote sensing methods, bathymetry, 3D-modelling of aquatic areas, water eutrophication researches. The theme of the paper is a review of the hydrological ecosystem field research. Research area is Bakota Bay in Dniester Canyon and adjacent territories. Main purpose of research is to evaluate potential reaction of environment to direct or indirect anthropogenic impact, as well as to solve problem of sustainable nature management according to expected state of environment. During the research of surface water in Dniester water area, a number of hydrophysical indicators have taken into account, as temperature fluctuations boundary, color, transparency, hydroacoustic and geomorphological data of the bottom relief in water area. Also some navigational hazards and sunken objects have determined. As a result of research, some scientific approaches and methods have reasoned. For researched local geosystem, the anthropogenic impact assessment is grounded on distributed in space in time environmental monitoring data. Specifically, it consists of the synthesis of contact and remote monitoring methods. Spatially-distributed nature of monitoring data allows using the power of actual GIS-technologies, which provide a large variety of multidimensional spatial analyst tools for various pollution factors evaluation. Authors insist that echolocation-based bathymetry is important method for solving problems of water resource management on researched area, which has international importance in the frame of planned Dniester Canyon hydro power cascade construction.
