AB: While a broad range of literature exists regarding regional climate forecasting using global circulation models (GCM) and downscaling techniques to assess hydrologic impacts, these often focus on relatively short lead times, use daily time steps, and focus on particular events such as low flows, extreme events, etc. However, few publications seem to focus on the long term evolution of a basin's water balance due to climate change impacts on regional hydrologic processes. And yet, this may be the most beneficial application of hydro-climatology to support long term water resources management and planning. A study in the San Pedro Basin contributes to this domain by modeling hydrologic impacts of IPCC climate change scenarios by downscaling - spatially and temporally - data from an ensemble of global circulation models over the next century. Depending on how climate change affects seasonal precipitation regimes, the impacts on ground water recharge are susceptible to vary significantly. Long-term changes in the basin's water budget are assessed using existing hydrological models for the San Pedro Basin. As this work provides a basis for the inclusion of climatic scenarios into the Basin's decision and policy-making process, an effort is made to clearly present a broad range of results corresponding to different scenarios for water managers and policy makers.
