摘要:We propose a numerical method for the computer simulation of the forest impact on aquifers. By this phenomenon it is mean the raising or the lowering of the groundwater table under the areas felled or recovered by the trees. The mathematical model of the forest impact includes a boundary-value problem with free and contact boundary conditions. Numerical results for an illustrative 2D test problem are discussed. The test shows that even in our model of forest impact, that takes into account only some principal characteristics of this phenomenon, the water table lowering owing to the forest suction is significative enough to be considered as an effective means for control of groundwater.
