4 4 - PEST in Visual MODFLOW The parameter estimization process is now an integral part of the Visual MODFLOW environment. The Chapter deals with • • • • • • Assigning Observations to Model Outputs, Choosing the Parameters to Optimize, Assigning Prior Information, Assigning the Objective Function, Controlling the PEST Run and, Starting the PEST Run. Assigning Observations to Model Outputs Visual MODFLOW allows you to relate observations of head, concentration and flow to model output values. All observations are input to Visual MODFLOW in the Input module. Head and Concentration observations Head and concentration observations are input in the Wells mode as seen below When either head or concentration observations are selected from the Wells drop-down menu, the observation values can be input in the following dialogue. This dialogue can be accessed whenever observations are being added or edited. Assigning Observations to Model Outputs 51
