• 3-D finite-difference model
• Open source, published by the U.S. Geological Survey
• Used version: MODFLOW-2005 http://water.usgs.gov
• The 3-D model domain (e.g. aquifer system) is discretized into a
block of grids called cells
• For each cell the hydraulic properties (e.g. conductivity, storativity)
are defined
• Layers correspond to horizontal hydrogeological units
• In each cell there is a point called “node” at which hydraulic head is
calculated

• Warm season => - river and soil water not frozen- groundwater recharge (10mm/year)
• GW-flow in alluvial aquifer from Southto North parallel to Kharaa River

Water balance:
Water flow into the model domain � Kharaa River larges contribution
Water flow out of model domain � pumping wells larges contribution
