Book Description
The San Joaquin - Tulare Conjunctive Use Model (SANTUCM) was originally developed for the San Joaquin Valley Drainage Program to evaluate possible scenarios for long-term management of drainage and drainage - related problems in the western San Joaquin Valley of California. A unique aspect of this model is its coupling of a surface water delivery and reservoir operations model with a regional groundwater model. The model also performs salinity balances along the tributaries and along the main stem of the San Joaquin River to allow assessment of compliance with State Water Resources Control Board water quality objectives for the San Joaquin River. This document is a detailed description of the various subroutines, variables and parameters used in the model.

Book Description
Land subsidence due to groundwater pumping in the San Joaquin Valley of California is known to cause many negative side effects, including a loss of groundwater storage. The general theory behind surface deformation, which includes subsidence and rebound, due to changes in the groundwater system, is well established. Surface deformation occurs as a direct result of changes in water level in an aquifer system, and can be permanent or recoverable, depending on the stress history of the aquifer system. An advanced satellite method known as Interferometric Synthetic Aperture Radar (InSAR) can be used to measure surface deformation with ~cm accuracy, at a resolution of ~100 m and measurements every 10 to 40 days. In spite of our ability to measure surface deformation with this method, and the existing theory describing the relation of deformation to changes in water level, it remains challenging to relate this deformation to changes in the aquifer system because so much information is required to do so accurately. The goal of this thesis is to develop methods to improve our ability to monitor and model groundwater storage and quality by incorporating InSAR with geological, geophysical and water quality datasets. This includes developing methods that estimate how much observed deformation is permanent, methods that predict deformation given water level changes, and methods that relate deformation to arsenic contamination. By integrating multiple datasets with InSAR, we are able to extract more useful hydrogeological information that provides water managers with tools to map and model deformation due to changes in the groundwater system, as well as its impacts on groundwater storage and quality. Our key findings are that 1) in the San Joaquin Valley, 54-98% of the subsidence that occurred from 2007-2010 throughout our study area was permanent, 2) by combining InSAR data with airborne electromagnetic (AEM) data, we are able to model surface deformation over time and improve estimates of the subsurface hydrostratigraphy, as well as hydrologic, geomechanical and rock physics parameters, 3) our modeling indicates that the land has subsided by as much as 3 m since 1990 in one specific location within our study area, and 4) land subsidence resulting from overpumping is linked to arsenic contamination in the San Joaquin Valley aquifer system.
