Estimation of Groundwater Flow Parameters Based on Simultaneous Calibration for a Series of Vertical Planar Models

The article describes an algorithm for simultaneous calibration of several groundwater flow vertical planar models. Permeability properties and boundary conditions are considered as calibration parameters. A special procedure that runs each model sequentially was developed. The calculated levels for each model are the result of procedure work. These calculated levels of observation wells are transferred to the PEST module. The PEST module uses it to evaluate the sensitivity of the model(s) to parameter values and then iteratively selects parameters so that they could satisfy the convergence criterion.
