Visual MODFLOW Flex Video Series – Numerical Modeling: Define Boundary Condition
In this video, our trainer Brayden McNeill discusses the methods for assigning boundary conditions during the numerical modeling workflow using Visual MODFLOW Flex. 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. The methods presented here will allow you to easily and quickly assign cell-by-cell boundary conditions to your groundwater models. 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).
The methods presented here will allow you to easily and quickly assign cell-by-cell parameter values to better represent your site geology.
