About article:
The aim of this article is the comparison of input options of river boundary condition to the three dimensional numerical simulation model of groundwater flow MODFLOW. The water level in the stream flowing through the territory of the hydrogeological layer can be computed via three built-in modules: RIV (River), STR (Stream) and SFR (Streamflow – Routing Package). We used MODFLOW to simulate idealized aquifer and stream. The differences between computed groundwater table showed to be minimal, thus in case of modules STR and SFR they are equally usable as using module RIV with external one or two dimensional simulation of surface water flow, which is more time – consuming process. However, this applies only to idealized, simplified conditions of the modeled environment. For more complex simulation of flow in streams with irregular structure of the riverbed is necessary to use either an external simulation or use the SFR module, which includes the possibility to enter a more complex hydraulic flow parameters in the model.
