Groundwater Models

Groundwater is an important resource, but availability, quality, and sustainability during growth have become major concerns. Groundwater models are numerical representations that help hydrologists better understand groundwater systems. These models also provide tools for water managers. The Utah Water Science Center has groundwater models for many seperate areas in Utah as well as two...

Paleoflood Investigations to Improve Flood-Frequency Estimates for Eastern Colorado

The peak-streamflow regional-regression equations (PSRREs) in the Plains hydrologic region in eastern Colorado have the largest uncertainty of any hydrologic region in Colorado. Reliable peak-streamflow information is critical for the proper design of stream-related infrastructure, such as bridges and dams, and flood-plain inundation maps. In an effort to provide more reliable peak-streamflow...

Current Streamflow and Water-Quality Monitoring at Select Sites in the Animas and San Juan River Basins, Colorado, New Mexico, and Utah

The USGS monitors current streamflow and water-quality conditions at various sites in the Animas and San Juan River Basins in Colorado, New Mexico, and Utah, including areas below the Gold King Mine release area. These streamgages provide continuous data on streamflow and select water-quality constituents including specific conductance, water temperature, pH, and turbidity.

USGS Science Centers in Region 7-Upper Colorado Basin produce hundreds of USGS-series publications, journal papers, and books each year that are subject to rigorous review by USGS specialists.

Multi-region assessment of chemical mixture exposures and predicted cumulative effects in USA wadeable urban/agriculture-gradient streams

Chemical-contaminant mixtures are widely reported in large stream reaches in urban/agriculture-developed watersheds, but mixture compositions and aggregate biological effects are less well understood in corresponding smaller headwaters, which comprise most of stream length, riparian connectivity, and spatial biodiversity. During 2014–2017,...

Simulation hydrologic effects of wildfire on a small sub-alpine watershed in New Mexico, U.S.

Streamflow records available before and after wildfire in a small, mixed conifer, sub-alpine monsoonal dominated watershed in New Mexico provided a unique opportunity to calibrate a watershed model (PRMS) for pre- and postfire conditions. The calibrated model was then used to simulate the hydrologic effects of fire. Simulated postfire surface...

Changing climate drives future streamflow declines and challenges in meeting water demand across the southwestern United States

Society and the environment in the arid southwestern United States depend on reliable water availability, yet current water use outpaces supply. Water demand is projected to grow in the future and climate change is expected to reduce supply. To adapt, water managers need robust estimates of future regional water supply to support management...

Hazards from induced earthquakes are a growing concern with a need for effective management. One aspect of that concern is the “nuisance” from unexpected ground motions, which have the potential to cause public alarm and discontent.
