Hydrographic and Landscape Description of a River Basin Based on GIS- and Geographic Data

B. I. Gartsman

The description of a river basin is the obligatory section of any project or scientific-and-ap- plication work in the area of hydrology, hydraulic engineering, and related problem areas. Present-day methods of the analysis of the territory including the description of a river basin should be based on the use of GIS-techniques and of the broad array of geographic data. This especially concerns mediumscale digital terrain models that are widely used at present, as well as the layers containing climatic and landscape information. Altogether this gives the principally new technological basis of the analysis, by many times increases the potential of obtaining detailed quantitative data on the morphometry and landscape structure of a basin, and provides the technical possibility of using the achievements of the structural and hydrographic analysis of river systems and of the landscape-hydrological approach.
