AB: This study describes research using the CASA (Carnegie-Ames-Stanford) ecosystem model with HYDRA surface hydrologic model for the state of California to understand the effects of potential land cover and climate events on mountain ecosystems and regional water resources. The models are run at 1-km resolution to capture localized topographic effects at the regional scale. To assess HYDRA's ability to estimate actual water flows in both extreme and non-extreme years, we have compared HYDRA's results with gauge station data throughout the state. Historical predictions for the Northern Coastal Range show that HYDRA's estimate of actual water flow improves as the model progresses downstream within a watershed. Other complex watersheds that display similar characteristics include the Klamath and the San Joaquin Valley. High resolution studies of land cover and surface hydrology are presented for the Central Coast Range of California, which is impacted by extreme events of fire and rapidly changing climate gradients.
