Water Supply
In 2004, the CCCC staff initiated studies of water supply reliability with literature reviews of climate impacts on water and agriculture in California [2] and of water resource models used to measure reliability [3]. Critical evaluation of the models indicated design problems a need for models better suited for estimating impact of climate change. The Center associates designed models of Sacramento and San Joaquin Valley hydrology, using a WEAP platform, to estimate the impact of climate change on water supply, cropping and groundwater conditions [4, 5].
The impacts of climate change on water supply reliability are summarized in two Center reports, which provide a detailed review of water supply impacts, by climate scenario, time period and location [6, 7]. A companion study estimated the impact of changes in water supply on groundwater pumping and groundwater levels [8]. The Center also conducted studies of the impact of climate change on water supply forecast accuracy [9, 10].
