Abstract:
As California enters its third year of drought, questions of future water sustainability are inevitable. Snowpack, soil moisture, streamflow, reservoir and groundwater levels are at record lows. Mandatory water restrictions are being implemented, statewide fines for wasting water have been authorized, and billions of dollars and tens of thousands of jobs have been lost. Enhanced monitoring and modeling of the state’s dwindling water supplies can help manage what remains while looking forward to a post-drought, sustainable water future. Here we demonstrate the role of satellite observations in comprehensive drought characterization and monitoring. In particular we highlight changing water supply, declining groundwater and reservoir levels, agricultural and urban stress. Potential contributions to water management will be discussed.
