OPTIMUM CONTROL OF THE GROUND-WATER LEVEL WITH ACCOUNT FOR A RAIN OR SNOW FALL-OUT
N. D. Bobarykina and K. S. Latyshevb UDC 556.324:517.97(06) Optimum ground-water conditions of a drained mass of a polder system having one conducting channel were simulated with account for a rain or snow fall-out. The calculations were conducted with the use of an invariant (independent of the number of conducting open channels and their configuration) nonstationary mathematical polder system, involving a strategy for control of the ground-water level in a drained mass (a system of Saint-Venant differential equations for an open channel, a two-dimensional Boussineq equation, and a differential equation for the transfer of water in drains were simultaneously solved). a Kaliningrad State Technical University, 1 Sovetskii Ave., Kaliningrad, 236000, Russia; b I.
