Monthly Diversions from the Surface Water Network of the Central Valley Hydrologic Model Version 2 (CVHM2)
This digital dataset contains the monthly diversions from the surface water network in the updated Central Valley Hydrologic Model (CVHM2) for water years 1922-2019. The volume of water transported by surface-water diversions were updated in the CVHM2 from several sources, including:
• The C2VSIM developed by DWR,
• The WestSIM model,
• Delta Mendota Canal turnout delivery data obtained from SLDMWA,
• Delta delivery data obtained from Montgomery Watson.
The surface water diversions are simulated through the Streamflow Routing Package (SFR2) using 571 diversion locations providing 564 semi-routed and 7 non-routed diversions. Linkages between SFR2 and the Farm-Process (FMP4) simulate the semi-routed and non-routed deliveries through the stream network from a specified diversion location. The semi-routed deliveries (SRD) are regulated by a diversion limit at each location so that FMP4 can only divert from the stream network up a certain amount, specified in the file, SRD_Diversion_Limit.csv. The non-routed deliveries (NRD) are “piped” from a diversion location to a given subregion to meet farm demand. A list of the diversion locations and associated subregions for the NRDs is provided in NRD_ID.csv. Simulating diversions in this way simplified how diversions were simulated and made it easier to account for the volumes from the diversions in the input and output datasets. When compared to the CVHM1, the number of diversions in the CVHM2 were greatly increased in the Delta as well as the Western San Joaquin Valley. This dataset also includes the diversion names, locations, monthly magnitudes, and the non-routed delivery model input file for FMP4.
