Description
Summary:This paper describes an algorithm for simultaneous calibration of several groundwater flow planar models. Permeability properties and boundary conditions are considered as the calibration parameters. A special procedure that runs each model sequentially has been developed. The resulting calculated levels by piezometers for each model are transferred by a PEST module. The PEST module uses this and estimates the sensitivity of the model (models) to the parameter values and then iteratively selects parameters so that they satisfy the convergence criterion.
