I need to know how to determine the discharge from the groundwater model, so that optimum pumping rate can be suggested to remediate the contaminated groundwater using pump and treat method.
To me the best way to perform this calculation in Visual MODFLOW is to use the Zone Budget facility which is one of the MODFLOW modules incorporated in Visual MODFLOW. This way, you can assign any desired zone, for which you aim to calculate the discharge, in the Zbud menu. Then you can read the result in the output (after running the model) under the Graphs menu for your defined region.
Please feel free to contact me ([email protected]) if you have further questions regarding Visual MODFLOW and its models.
I agree with Peyman Babikhani....in fact that is the only way to estimate the inflow and outflow from any groundwater system if you use MODFLOW....only thing is that the accuracy depends on the number of zone (assumed during model) .... If you do the donation based on groundwater .....u will get good result....all the best....feel free to contact me if u have any query to [email protected]
