Global Climate Change Response Program: Evaluation of Central Valley ProjectWater Supply and Delivery Systems

摘要

A simple mass balance reservoir operation for the Central Valley Project (CVP)and State Water Project (SWP) water systems, California, was used to assess the possible global climate change impacts to the CVP. Historic hydrologic parameters were modified in an attempt to reflect possible hydrologic conditions under global climate change. Four different simulation cases were analyzed over a 57 year period using graphical techniques. The CVP, using current operations criteria, was found to be very sensitive to the climate change scenarios. The climate change induced shift of reservoir inflow from spring to winter results in a loss of potential water storage which leaves the CVP vulnerable to dry periods.
