This digital dataset consists of monthly climate data from the Basin Characterization Model v8 (BCMv8) for the updated Central Valley Hydrologic Model (CVHM2) for water years 1922 to 2019. The BCMv8 data are available in a separate data release titled "The Basin Characterization Model - A regional water balance software package (BCMv8) data release and model archive for hydrologic California, water years 1896-2020". The data were modified by: (1) extracting the data from the data source for the relevant model domain and times, and (2) rescaling the 270-meter BCMv8 grid to the small watersheds that contribute boundary flow to the CVHM2 model for the hydrologic variables recharge and runoff. The three data pieces...

This digital dataset contains the climate data used for the Lower Salinas Valley Hydrologic Models (Salinas Valley Integrated Hydrologic Model (SVIHM) and Salinas Valley Operational Model (SVOM)). The monthly climate data for the Lower Salinas Valley Hydrologic Models are based on the regional climate data for the Salinas Valley Hydrologic System [Hevesi and others, 2022]. To develop the monthly climate grids, the regional climate data were resampled to a monthly timescale and area weighted to the model grid. The climate data include spatially distributed monthly precipitation and potential evapotranspiration for the model grid for October 1967 to September 2018.
This digital dataset contains three types of information about the land use properties used in the updated Central Valley Hydrologic Model (CVHM2): land use shapefile showing primary land use type for a model cell through time, soil data using the curve number for each region and zone, and farm process parameter values including crop coefficients and rooting depths.

This data release documents the datasets and procedures used to update the Los Angeles Basin Watershed Model (LABWM) (Hevesi and Johnson, 2016) from INFIL3.0 (USGS, 2008a, 2008b) to INFIL4.0. The LABWM provides gridded monthly infiltration, evaporation, recharge, and runoff estimates for the Los Angeles region using the water balance recharge model, INFIL. INFIL is a grid-based, distributed-parameter, deterministic model that uses a daily time step to simulate the temporal and spatial distribution of the root-zone water balance, including net infiltration and potential recharge across the lower boundary of the root zone. INFIL3.0 was originally released and documented in 2008 (USGS, 2008a) and has been used and...
Managed aquifer recharge is a water-management strategy used to meet water demands during dry periods, or periods of high-water demand, when surface-water supplies are low. One method of managed aquifer recharge uses aquifer systems as subsurface reservoirs or ‘water banks’ to effectively and economically store surface water when surplus is available, and then recover the recharged groundwater to meet water demands during droughts. During these water shortages, increased groundwater pumpage can be used to offset shortfalls in surface-water supplies. Thus, surface-water reservoirs and water banks can be used conjunctively to effectively coordinate the use of groundwater and surface water. Data were compiled for ten...

The model setup of the updated Central Valley Hydrologic Model (CVHM2) is similar to the original Central Valley Hydrologic Model (CVHM). The differences in the model setup are described here as either model discretization, tidal influence, or drain flow. For model discretization, CVHM2 has 13 layers compared to 10 in CVHM. Tidal data for the San Francisco Bay and its influence on the general head boundary was added in CVHM2. Drain flow was not included in CVHM1 for the west side of the San Joaquin Valley, and was added in CVHM2.
This digital dataset contains the Hot-Dry (HD) climate scenario data used for the Salinas and Carmel Rivers Basin Study (SCRBS).

This digital dataset contains the gridded future climate data used for the Lower Salinas Valley Hydrologic Models. The monthly climate data for Lower Salinas Valley Hydrologic Models are based on the Salinas and Carmel River Basins Study (SCRBS) future climate scenarios [Henson and others, 2024). SCRBS considers one baseline climate scenario that represents recent historical climate conditions and five future climate scenarios: Hot-Wet (HW), Warm-Wet (WW), Hot-Dry (HD), Warm-Dry (WD), and Central Tendency (CT) (Henson and others, 2024). To develop the monthly climate grids, the regional climate data was resampled to a monthly timescale and area weighted to the model grid. The climate data includes spatially distributed...
This digital dataset contains the monthly inflows and diversions to the surface-water network in the updated Central Valley Hydrologic Model (CVHM2) for water years 1922-2019. The surface-water network simulates the Central Valley’s complex conveyance network through the Streamflow Routing Package (SFR2) and the Farm-Process (FMP4) at 65 inflow locations with 271 stream segments that represent 4043 stream reaches and 13 bifurcations, and 571 diversion locations providing 564 of semi-routed diversions and 7 non-routed diversions. The semi-routed deliveries are routed through the simulated surface-water network, while the non-routed delivery is simulated through linkages between the SFR2 and FMP4 packages in MODFLOW-OWHM....
This digital dataset contains the Central Tendency (CT) climate scenario data used for the Salinas and Carmel Rivers Basin Study (SCRBS). The Central Tendency (CT) climate scenario is based on the 50th percentile change in precipitation, 50th percentile change in temperature.

This digital dataset contains the surface water data used for both the Salinas Valley Watershed Model (SVWM) and the Lower Salinas Valley Hydrologic Models (Salinas Valley Integrated Hydrologic Model (SVIHM) and Salinas Valley Operational Model (SVOM)). The surface water dataset includes two regions of the Salinas River Watershed; the upper region is primarily within San Luis Obispo County, California and lower region of the Salinas River Watershed is contained within Monterey County, California. Subcatchments within the Salinas River watershed were delineated using the U.S. Geological Survey (USGS) 10m digital elevation model (DEM), USGS National Hydrography Dataset Best Resolution (NHD) watershed boundaries, and...
This digital dataset contains the soil data for the updated Central Valley Hydrologic Model (CVHM2). The soil data is based on California Department of Water Resource’s C2VSim’s fine grid model soil curve number data set (C2VSimFG Version 1.0 - Datasets; CNRA, 2011). These values were originally obtained from the U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) Soil Survey Geographic Database (SSURGO) soil map of the State of California (USDA, 2004), and then an area-weighted average value for each hydrologic soil group within each subregion was calculated to the C2VSim element. Curve number values obtained from SSURGO were converted for use in C2VSimFG. To translate the curve...

This digital dataset contains the baseline and future climate data used as the basis for analysis of current and future water supplies and demands in the Salinas and Carmel Rivers Basin Study (SCRBS). SCRBS uses a suite of integrated hydrologic models to explore impacts of future climate and socioeconomic scenarios on water supplies and demands in the basins. SCRBS considers one baseline climate scenario that represents recent historical climate conditions and five future climate scenarios that encompass the range of uncertainty in projections of future climate conditions through the end of the 21st century. The baseline scenario was developed by removing trends from an observed historical climate dataset such that...
This digital dataset contains the Warm-Dry (WD) climate scenario data used for the Salinas and Carmel Rivers Basin Study (SCRBS). The Warm-Dry (WD) climate scenario is based on the 10th percentile change in precipitation and the 10th percentile change in temperature. The files included in this child item are the daily 270-meter gridded spatially distributed daily precipitation (PPT), maximum and minimum air temperature (TMX and TMN, respectively), and potential evapotranspiration (PET) from 1/1/2016 to 12/31/2100.
This digital dataset contains the location and timing of the virtual farm wells for the updated Central Valley Hydrologic Model (CVHM2). Farm wells are simulated as virtual wells and the screen lengths based on those calculated for the original Central Valley Hydrologic Model (CVHM; Faunt and others, 2009). Farm wells are all simulated as multi-node wells (MNW), which allows for a more realistic distribution of pumping by demand for each water balance subregion. Agricultural Pumping are estimated in CVHM2 by the farm process, and thus are not included in the virtual farm well child item.
The Lower Salinas Valley Hydrologic Models’ discretization data includes a shapefile of the model domain and layers and a shapefile of the water balance subregions. The Lower Salinas Valley Hydrologic Models (LSVHM) include a historical model, the Salinas Valley Integrated Hydrologic Model (SVIHM) and a reservoir operations model, the Salinas Valley Operational Model (SVOM). While the Lower Salinas Valley Hydrologic Models have different purposes, they have the same model extent and many of the same input datasets, including the discretization data included in this data release. The model domain for the Lower Salinas Valley Hydrologic Models includes the Salinas Valley groundwater basin and extends offshore to...
