Activities and outcomes during past year:
This project aims to develop a three-season groundwater model of the Upper San Pedro with several notable improvements. To develop a three season model of the San Pedro basin, one must start with a calibrated annual model. To this end, the development could have proceeded in several ways. Creating a new groundwater model is the least desirable option as it is not timely and expensive. Initially, it was thought that the newly released USGS model could be modified. However, difficulties with the model made this option impractical. The third option is to modify the existing Goode and Maddock model. This option has been explored in detail. Each of the input packages have been converted to Groundwater Modeling System 9, the current modeling tool in use, and explored for errors and updates. Because the existing model was constructed prior to the use of elevation data in MODFLOW models (layer depths were used and calculations were relative) the existing layer structure is not useable. However, many of the remaining packages offer good starting points and can be modified. Thus, a new model will be created using input packages from Goode and Maddock, with the new layer data incorporating the gains of the USGS model.
