Overall, system yields will decline everywhere. Nevertheless, reservoir systems in the eastern United States will become more resilient and less reliable under climate change, whereas western systems will become less resilient and less reliable. Task E Validation of Regional Hydroclimatologic Modeling Approach. Work is underway to calibrate and validate regional hydroclimatologic watershed models for all regions of the United States. In addition, work is under way to evaluate the climatic elasticity of streamflow across the United States.
Improved methods are under development for estimation of the climate elasticity of streamflow.
Task F Determination of Vulnerability Indices Under Current and Future Climates. This work is described in a paper and was summarized in the proceedings publication for the 25th Annual Conference of the Water Resources Planning and Management Division. Task G Comparison With Previous Studies. This task has not yet begun. Task H Regional Assessment of the Impact of Climate Change on Water Resources.
