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...

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.
