From engineering geomorphology to environmental geomorphologic studies

Abstract

The paper considers geomorphological aspects of «geo-ecological hazard» notions. Pollutants accumulation and concentration are shown to depend on structure of river basins, which are subdivided into three categories: basins-accumulators, transit basins, and basins disposing of pollutants. A possibility is shown to apply the basin approach to studies of pedologic-geochemical (catenas) organization of an area. Techniques are developed to calculate an index of ecological-geomorphological hazard.
