| Abstract: | A geomorphic regionalization of the main river valleys of Siberia is proposed for purposes of selecting potential sites for hydroelectric power stations. The regionalization is based on geomorphic features that relate to the stability of dams and to construction conditions: valley morphology; composition and thickness of sediments; geological structure and properties of dam-foundation rocks; permafrost and slope processes; seismic activity; local availability of building materials. Six basic regions are distinguished: mountains, plains, the intermediate piedmont, trap plateau, stratified plateau, tableland. Potential dam sites are listed for each major region together with projects that have been completed or are in progress. |
