California Central Valley Groundwater Modeling Workshop

Central Valley Groundwater Modeling Workshop - July 10 - 11, 2008

Organized by Charlie Brush, DWR, and Norm Miller, LBL/UCB

California’s Central Valley is currently home to over 6 million people, and generates over $20 billion in agricultural crops each year. An intricate surface water distribution system routes water from surrounding watersheds to the Central Valley, the Central Coast and Southern California. The Central Valley’s aquifers have historically provided water for agricultural and urban use, and are increasingly being used as a buffer for fluctuations in surface water supplies. Current scientific and management challenges include understanding the aquifer’s response to drought and climate change, protecting the quality of groundwater, limiting subsidence caused by groundwater pumping, and implementing aquifer storage and recovery programs.

This workshop was a gathering of researchers, consultants, administrators and others interested in learning about how groundwater models have been applied to address scientific and resource-management questions in the Central Valley. The workshop followed the Computational Methods in Water Resources XVI International Conference, held in San Francisco July 6-10, 2008. Workshop presentations were developed to increase attendees understanding of the groundwater flow system at both the local and regional scales, and to foster discussion on future collaborations and sharing of models and data.

The workshop began with a dinner gathering July 10th at Looney’s Barbeque in Berkeley. Dave Prudic of the original USGS Central Valley Regional Aquifer System Analysis team gave a presentation on the history of groundwater modeling in the Central Valley. The meaning of the term ‘groundwater model’ has changed over the years, from a set of painted wooden dowels representing well logs, to analog models created with resistors and capacitors, to the current digital computer models.

On Friday, workshop attendees met at UC Berkeley to see twenty presentations on groundwater models developed for the Central Valley. The morning session included four groundwater flow models in the Tulare Basin and five in the San Joaquin River Basin. The afternoon session included four more models in the San Joaquin River Basin, three in the Sacramento River Basin, and closed with four presentations on Valley-wide modeling efforts.
