GSFLOW, used to run PRMS and MODFLOW-NWT models, to simulate the effects of natural and anthropogenic impacts on water resources in the Rio San Jose Basin and surrounding areas, New Mexico

The Rio San Jose Integrated Hydrologic Model (RSJIHM) is a sequentially linked, integrated hydrologic model utilizing the Precipitation-Runoff Modeling System (PRMS) (version 5.2.0) and MODFLOW-NWT (version 1.2.0) that was developed to provide a tool for analyzing the hydrologic system response to historical water use and potential changes in water supplies and demands in the Rio San Jose Basin. PRMS and MODFLOW-NWT were run uncoupled using the U.S. Geological Survey developed GSFLOW executable (version 2.2.0). The study area encompasses about 6,300 square miles in west-central New Mexico and includes the communities of Grants, Bluewater, and San Rafael and three Native American tribal lands: the Acoma and Laguna Pueblos and the Navajo Nation. The study area has a scarcity of perennial surface-water features and most water resources consist of groundwater pumped from sedimentary and basaltic aquifers. The transient simulation period for the RSJIHM extends from January 1, 1950 through September 30, 2018. The period from 1944 through 1949 was chosen to simulate steady-state conditions and to provide initial heads for the transient MODFLOW-NWT. This U.S. Geological Survey data release contains all the input and output files for the RSJIHM documented in the associated model report (https://doi.org/10.3133/sir20235028).
