Conceptual Modeling: Define Boundary Conditions Video

0
This video describes the sixth step in the conceptual modeling workflow: Defining Boundary Conditions.

Defining boundary conditions is a very important step in the numerical modeling process, since this is how you can incorporate real world hydrogeologic features into your model. In the conceptual modeling workflow supported by Visual MODFLOW Flex, all boundary conditions are assigned using existing data objects. Use shapefiles (polyline/polygon/points) to describe the location of boundary conditions, and assign attribute values to these boundary conditions as constant values or using shapefiles, surfaces, or 3D gridded data.

Supported boundary conditions in Visual MODFLOW Flex include constant heads (.CHD), rivers (.RIV), general head (.GHD), drain (.DRN), wall (.HFB), recharge (.RCH), evapotranspiration (.ETS), lake (.LAK), specified flux (.FHB1) and well (.WEL) boundary conditions. Some additional boundary conditions are supported in selected engines (e.g. the time-varying materials (.TMP) or seepage (.RSF4) packages supported by MODFLOW-SURFACT).
