In the article is shown the approach to a research on hydropower resources in Western Siberia. The hydropower potential estimates are ba sed on the following factors: water content of rivers, river slopes and flow velocities. Identified are the portions of rivers with largest energ Сѓ capacity and the possibility to use hydro potential. A measure of hydrological tension was cal culated, which takes in to account the quantitative characteristics of following factors: low water, ice effect s, high water, sediments r...
