Monthly Inflows to the Surface Water Network for the Central Valley Hydrologic Model Version 2 (CVHM2)

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2023-12-11T00:00:00Z
This digital dataset contains the monthly inflows to the surface water network in the updated Central Valley Hydrologic Model (CVHM2) for water years 1922-2019. The surface water inflows are simulated through the Streamflow Routing Package (SFR2) using 65 inflows locations, 271 stream segments that represent 4043 stream reaches, and 13 bifurcations that comprise the stream network. The bifurcations simulate the bypass canals that are used for flood control by routing water between two stream reach locations within the stream network. This dataset includes the inflow and bifurcation locations, monthly magnitude, and shapefiles of the gridded and non-gridded stream network.
