The influence of lower-boundary condition on the groundwater flow system

Abstract

Modeling is essential for the investigation of material-energy transport processes below the surface. During the construction of groundwater flow models hydraulic conditions are usually not considered below the investigated space. The boundary conditions are mostly fixed at the border; i.e. there is no flow across the boundary. However, this condition is not tenable in every case, so its practical applications may lead to false conclusions. The present paper shows how the flow geometry changes with the modification of the lower-boundary condition and fault zone conductivity in a study area near Debrecen, NE Hungary.
