Abstract:

This paper describes the results of groundwater modeling in the Tustin/Irvine basin situated in the southeastern portion of the Tustin plain, which is the the southern extension of the Coastal plain underlying Los Angeles County, CA. The U.S.G.S. Modular 3 - dimensional finite difference code was used to model the groundwater flow field. The study area was horizontally discretized into a mesh of 47 columns and 32 rows. Vertically, the model consisted of 3 layers with controlled vertical leakage between the layers, to simulate semi-confined conditions between water bearing and non-water bearing materials. The model was calibrated against field data. Hydrogeologic parameters, such as transmissivity, recharge and storativity were changed to test the sensitivity of the model.
