Selecting Suitable MODFLOW Packages to Model Pond–Groundwater Relations Using a Regional Model

In large-scale regional models, used for the management of underground resources, it is quite common to find that relationships between aquifer and small wetlands are not included. These models do consider this connection because amount water involved, but they should potential significant ecological impacts if groundwater resources in ecosystems associated with these mismanaged. The main objective work investigate possibilities offered by MODFLOW LGR-V2 represent (at scale) Santa Olalla pond, located Doñana Natural Park (South Spain), its relationship Almonte-Marismas aquifer. As a secondary objective, we propose advantages disadvantages DRAIN, RIVER LAKE packages offer within discretizations. drain boundary condition coarse discretization implemented through ModelMuse allows most adequate performance levels environment pond. However, when using lake condition, use version particularly useful. present also gives some guidelines employ graphical user’s interface, 4.2.
