Examples of numerical solution of models of hydrological cycle with both concentrated and distributed parameters. are given. The examples considered are adapted to the level of students of the III course . The peculiarity of the "Practice" is that students are invited to first solve examples "manually", and then, after acquaintance with elements of the C++ language, by drawing up appropriate programs.
