| dc.description.abstract | The problem of evaluating the parameters of the mathematical model of an unconfined aquifer is examined with a view toward development of automated or computer-aided methods. A formulation is presented in which subjective confidence ranges for each of the model parameters are quantified and entered into an objective function as linear penalty functions. Parameters are then adjusted by a procedure which seeks to reduce the model error to acceptable limits. A digital computer model of the Tucson basin aquifer is adapted and used to illustrate the concepts and demonstrate the method. | |
