EVAPOTRANSPIRATION FACTOR IN 3D MATHEMATICAL MODELING OF GROUNDWATER LEVEL CHANGES

Abstract

For the first time, the boundary conditions of the groundwater level changing mathematical model in 2D and 3D formulation have been developed. Mathematical model takes into account artificial coverings on the soil surface and groundwater discharge processes due to evapotranspiration to improve predictions and management of groundwater level on the builtup areas. Three-dimensional modeling of groundwater level changing in contrast to two-dimensional allows to take into account the dependence of evapotranspiration on the presence of artificial coverings on the soil surface, which are located unevenly and have different filtration coefficients, which causes corresponding groundwater level changes of urban areas.
