i08 C2VSimFG Small Watersheds

The small watersheds are the minor unguaged rim watersheds that provides the additional surface water inflow into the stream network and subsurface inflows of the C2VSimFG. There are a total of 1,024 small watersheds along the northern, southern, western, and eastern boundaries of the Central Valley that covers 6,662 square miles. The dataset is a boundary condition of the model used to stimulate the time-dependent surface and subsurface flows from the small watersheds outside the Central Valley. The C2VSimFG uses the monthly surface water discharge, recharge, and subsurface groundwater flows data from the small watersheds to calculate the output water budgets. The small watersheds are delineated using the USGS Watershed Boundary Dataset (WBD) HUC 12. The areas calculated for this data using the WGS 1984 Web Mercator projection may not reflect the actual areas used in the C2VSimFG model.
