While the Lower Salinas Valley Hydrologic Models have different purposes, they have the same model extent and share similar datasets. The following datasets are common files that are applicable for both of the Lower Salinas Valley Hydrologic Models: Salinas Valley Integrated Hydrologic Model (SVIHM) and Salinas Valley Operational Model (SVOM). Datasets unique to each Lower Salinas Valley Hydrologic Model can be found in their respective model folder in the “Lower Salinas Valley Hydrologic Models” folder.
The Paso Robles groundwater basin (PR) encompasses approximately 500,000 acres and is located in the upper portion of the Salinas River watershed in the San Luis Obispo (SLO) and Monterey counties, Central Coast region of California (.\ancillary\Figures\Figure 1. Site Map.tif from this data release; California Department of Water Resources, 2003). Agriculture makes up a large part of the regional economy and agricultural water demand is the single largest component of total water demands in San Luis Obispo County (SLO; Fugro West, Inc and others, 2005). As such, future water supply sustainability is an important water management objective. To quantitatively evaluate long-term trends in groundwater levels, inflow,...

The Salinas Valley Hydrologic System provides data describing the hydrologic system, including the regional climate and the hydrologic models for the Salinas Valley. For the Salinas Valley Hydrologic System, the Salinas Valley is further subdivided into the upper and the lower Salinas Valley; the upper region is primarily within San Luis Obispo County, California while the lower region of the Salinas River Watershed is fully contained within Monterey County, California. The Salinas Valley Regional Climate includes spatially distributed daily precipitation, maximum and minimum air temperature, and potential evapotranspiration (PET) for both the upper and lower Salinas Valley. The Salinas Valley Hydrologic Models...
The Salinas Valley Operational Model (SVOM) is a model of the lower Salinas Valley that was developed to simulate reservoir operations for the San Antonio and Nacimiento Reservoirs to support conservation, fish passage, and support downstream agricultural diversions. The SVOM is a modified version of the Salinas Valley Integrated Hydrologic Model (SVIHM) that employs a new Surface Water Operations (SWO) module for MODFLOW-OWHM to simulate reservoir operations using rule-based logic and internal hydrologic flows within each simulation. Datasets presented here are unique to SVOM and are not shared with SVIHM, while files in common for both SVIHM and SVOM can be found in a shared folder in the directory above.
California’s Salinas Valley is one of the most productive agricultural basins in the world due to the fertile valley soil, temperate climate, and availability of water for irrigation. In the Salinas Valley, many people, industries, and ecosystems depend directly or indirectly on groundwater. Water demands and met by conjunctive use, which is the coordinated use of surface water and groundwater to meet the demand for irrigation and public water supply. Due to the high cost of groundwater development projects, it is important to understand how these projects perform to increase storage, mitigate seawater intrusion, provide flood control, and maintain healthy riparian ecosystems. The models from this study can be used...
The Lower Salinas Valley Hydrologic Models include the Salinas Valley Integrated Hydrologic Model (SVIHM) and the Salinas Valley Operational Model (SVOM). The Lower Salinas Valley Hydrologic Models were built using MODFLOW-One-Water Hydrologic Flow Model version 2 (MODFLOW-OWHM, Hanson and others, 2014; Boyce and Others, 2020) with the latest version of the MODFLOW Farm Process (FMP4). The SVIHM was developed to simulate historical hydrology, provide a detailed transient analysis of changes in groundwater and surface-water availability, and evaluate how historic and current management projects affect reservoir storage, surface-water flows, land use and associated pumping demands, groundwater-level elevations, and...
This data set provides the supporting data for the publication "What Makes a First Magnitude Sping?--Global Uncertainty Analysis of a Speleogenesis Model to Gain Insight into Karst Spring Genesis". This publication documents a speleogenesis model that was used to generate karst networks. Morris Method Global Sensitivity Analysis (MM-GSA) is used to efficiently sample input parameters to define a potential karst network. The MM-GSA provides information about sensitivity of hydrologic and transport response metrics (e.g., peak flows, peak timing, mass flux) to evaluated input parameters (e.g. network density, proto-conduit length distribution). There were 390 models in the analysis, therefore one replicate is provided...

The Salinas Valley Hydrologic Models include the Salinas Valley Surface Water Network, and the Lower Salinas Valley Hydrologic Models. For the Salinas Valley Hydrologic Models, the Salinas Valley is further subdivided into the upper and the lower Salinas Valley; the upper region is primarily within San Luis Obispo County, California while the lower region of the Salinas River Watershed is fully contained within Monterey County, California. The Salinas Valley Surface Water Network covers the upper and lower Salinas Valley regions and includes datasets defining sub-catchments, the location of the stream network, and existing streamflow gage locations. The Lower Salinas Valley Hydrologic Models include the Salinas...
