Modeling the interaction between water flows

Approaches to schematization used in the models of interacting water flows in different media are considered. Studies of the interaction between subsurface and surface waters are analyzed. Specific features of water flow-out from watercourses (channels), pipelines, etc. are discussed. Some steady-state problems are formulated, and their solutions are given. Dynamic effects of pressure changes in water flows are shown based on these solutions. The effects that appear in such cases are explained theoretically and correlated with experiments.
