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).
