Structure equivalence models (SEM), a new concept in groundwater modeling, have been developed to assist in groundwater planning and management. Using SEM, the engineer is able to satisfy the accuracy requirements with the least complicated conceptual model possible. For the purpose of finding this least complicated model, a technique called geological parameterization has also been developed, keeping the dimension of parameterization independent of the complexity of the model structure. In applying this new concept to the planning and management of the Hemet Basin in Riverside, California, we have found that a two-dimensional model with 9 different hydraulic conductivity values is adequate for our proposed model application.
