Abstract
The need to preserve and restore the natural environment, to ensure the environmental safety of geographical entities are priority conditions for the implementation of a dominant social paradigm –balanced development (in harmony with nature). At the same time, river basin is the unit of management, planning and design of environmentally safe geographical entities. The use of geoinformation technology plays an important role in the study of the structure and morphometric parameters of river basins. Based on the data analysis by ASTER GDEM, as well as a digital topographic base of 1:100 000 scale in the environment of ArcGis software product and Spatial Analyst module, a 3-dimensional model of the earth’s surface was designed to study the structure and morphometric parameters the Opir river basin. The boundaries of the basin have been determined, streams of different orders have been identified. An angle and exposure of slopes were determined. The analysis of the structure of the basin and morphometric parameters was performed by comparing their mean values and percentages.
