Numerical investigations for solution of hydraulic problems

Several universal software packages for the numerical modeling of open flows have been registered in the Russian Patent Office. Original numerical algorithms, and adaptive triangular-tetragonal grids, as well as hybrid modeling are used in solving problems. A combination of industrial computer techniques, modern information and measurement technologies, and approved forecasting systems make it possible to build computerized hydraulic models of the head and tail races of hydro-projects with an expanse in the hundreds of kilometers. They permit analyses of actual entities with complex bathymetry and configurations in plan with consideration of roads, bridge crossings, shoreline-protecting dikes, and other structures in the tail-race. Mathematical models and algorithms, which adequately reflect the phenomena under consideration, are the basis of computerized modeling. Methods of numerical modeling in riparian hydraulics, which have been developed by Russian scientists, are not inferior to foreign methods in terms of quality.
