California's Water Futures: How Water Conservation and Varying Delta Exports Affect Water Supply in the Face of Climate Change.

摘要

hanges in climate, population, water conservation, and the Sacramento-San Joaquin Delta will affect water management, the economy, and the environment in California. This thesis uses an integrated statewide hydro-economic model to examine the water supply and cost implications of changes in urban water conservation, Delta export capacity, and a dry form of climate warming for water management in California with population and infrastructure conditions projected for 2050. Adaptation options include coordinated use of system re-operation, remaining Delta pumping capacity, urban and agricultural water conservation, water markets, conjunctive use of ground and surface water, seawater desalination, and expanded water recycling. Results indicate that, depending on climate and Delta export conditions, conserving 30% of California's 2000 level urban demands (bringing urban use down to 154gpcd) could save California
