摘      要：The erection of large hydroelectric power stations leads to appreciable changes in hydrothermal and ice river regimes both above and below the hydroscheme. The river regime change affects the adjacent areas ecology. To estimate completely the ecologic effect of designed and already constructed hydroelectric power stations, it is necessary to determine the hydrothermal and ice river regime changes. As a methodical basis for the construction of a set of computer algorithms, a method of splitting by physical processes and the module principle has been used. Among the hydro-ice-thermics problems of rivers and water reservoirs are the following: the determination of the temperature regime of a water reservoir, an investigation of stratified flows in a weakly-running water reservoir;an investigation of a hydrothermal river regime;an investigation of ice cover edge dynamics in the downstream of a river. For every problem, mathematical models of different levels of complication and computer programs have been worked out.
