The National Hydrologic Model (NHM) is a modeling framework which has been applied to the continental United States through the Precipitation Runoff Modeling System (PRMS). The PRMS model of Puerto Rico extends the NHM and allows the simulation of rainfall-driven hydrologic conditions in the Commonwealth. Calibration of the NHM Puerto Rico model involved an initial manual calibration to understand the important processes and develop a basic representation of the hydrology. This is followed by an automated calibration procedure using the Let Us CAlibrate (LUCA) multi-objective function model calibration tool. A four-step procedure is used in Luca to separately calibrate parameters for solar radiation, evapotranspiration,...
The U.S. Geological Survey, in cooperation with the California Department of Water Resources (DWR), has constructed a new spatially distributed Precipitation-Runoff Modeling System (PRMS) for the Merced River Basin (Koczot and others, 2021), which is a tributary of the San Joaquin River in California. PRMS is a deterministic, distributed-parameter, physical-process-based modeling system developed to evaluate the response of streamflow and basin hydrology to various combinations of climate and land use (Markstrom and others, 2015). Although further refinement may be required to apply the Merced PRMS for official streamflow forecast operations, this application of PRMS is calibrated with intention to simulate (and...

The Red River Basin of New Mexico, Oklahoma, Texas, Arkansas, and Louisiana was chosen as a focus area study (FAS) as part of the U.S. Geological Survey (USGS) National Water Census (NWC). The objective of the NWC is to place technical information and tools in the hands of stakeholders so that they can make decisions on water availability. With this set objective, the USGS Water Science Centers in New Mexico, Oklahoma, Texas, Arkansas, and Louisiana conducted a study of water use and availability for the Red River Basin to improve water withdrawal estimates and investigate trends in water resources under future climate conditions and increased water withdrawals using groundwater and surface-water models (MODFLOW...

This data release contains input and output data from hydrologic simulations of streamflow conditions in the Red River Basin (RRB) using the Precipitation-Runoff Modeling System (PRMS). The RRB PRMS model predicts components of the water balance at 3065 hydrologic response units (HRU) and streamflow for 1614 stream segments within the model domain for the simulation period 1981 to 2016. The data release contains two shapefiles: (1) a map of HRUs in the model domain and (2) a map of stream segments in the model domain. In addition to the shapefiles, the data release includes files containing the calibrated parameters of the RRB PRMS model as well as model inputs and outputs. The model inputs are (1) climate data,...

This model archive contains 20 Precipitation-Runoff Modeling System (PRMS) models for 20 catchments within the Lake Michigan watershed (Mei and others, 2022). PRMS is a process-based distributed deterministic watershed model designed for the simulation of hydrologic processes including evaporation, transpiration, runoff, infiltration, interflow, and groundwater flow (Markstrom and others, 2015). The PRMS model version 5.2.0 (Markstrom and others, 2015) within the Ground-water and Surface-water FLOW (GSFLOW version 2.2.0) modeling platform (Markstrom and others, 2008) was used to construct the 20 catchment models. Each of the catchment models was calibrated using six different calibration schemes that are either...
A three-dimensional, GSFLOW model was developed to simulate and quantify the hydrologic system of the Yucaipa subbasin. The model was calibrated to conditions from 1970 to 2014, the period for which data are most complete and reliable. The model was used to (1) quantify the effects of historical and potential water-resource development induced by climate changes and human-related activities, and (2) to derive components of the daily water budgets for the components of the integrated model for calendar years 1970–2014 (long-term average), with particular attention given to groundwater budgets for dry and wet periods. The model also was used to assess the effects of pumping and climate stresses on hydrologic-budget...
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...
Description of Work USGS scientists are developing science based forecasting tools that capture changes to water flows and discharges of nutrients and sediments to the Great Lakes. The work done by this project provides managers with forecasting tools for predicting the combined effects of climate and land use changes that will help them identify and prioritize the sites best suited for restoration efforts. USGS scientists will use remote-sensing data to establish a baseline understanding of current distributions of invasive wetland plants and then forecast potential invasion corridors. Alterations to the Great Lakes shoreline or water-level patterns associated with global climate change could have significant impacts...

Eastern Montana Fisheries Community is using ScienceBase to document and study future streamflow and fisheries data in eastern Montana. Streams in the Northern Great Plains provide critical “green lines” of habitat for aquatic and terrestrial wildlife. The fish in these streams have evolved to survive heat, cold, floods, and drought. However, changes in water quantity associated with global climate change may transform some prairie streams from essential refuges to habitats no longer capable of supporting fishes. U.S. Geological Survey researchers and their partners are studying these potential changes in stream ecosystems in the Montana portion of the northern Great Plains. The Precipitation-Runoff Modeling System...
A comparison of hydrologic simulations in the lower Apalachicola-Chattahoochee-Flint River Basin, southeastern United States. This project provides technical assistance in integrating the Waterfall instream flow models developed for the South Atlantic LCC by RTI with the PRMS models being developed in the neighboring Gulf Coastal Plains and Ozarks LCC.
