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...

New Methods for Dating and Sequencing Ancient Earthquakes Along the Wasatch Fault Zone

Release Date: OCTOBER 12, 2018

Complex geologic sites, like those between the fault segments along the Wasatch fault zone in Utah, make the dating and ordering past earthquakes a difficult task. Two new methods were used to make this task easier and to get better results.

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...

Peak-streamflow , Mean-streamflow , and Low-streamflow Equations for Western Colorado

Reliable peak-streamflow data are critical to design transportation infrastructure, such as bridges, culverts, dams, and floodplain inundation maps. At gaged sites, where sufficient long-term streamflow data have been collected, statistics can be obtained from available publications, by an analysis of available data in the U.S. Geological Survey (USGS) National Water Information System (NWIS)...

Mesozoic magmatism in Montana

From crystalline batholiths with footprints larger than 4,500 km2 to beds of micron-sized ash particles, a record of Mesozoic magmatism is found throughout Montana. Mesozoic igneous rocks are an important natural resource in the state because of their association with precious metal ores and industrial mineral deposits. Mesozoic magmatism in...

River terrace evidence of tectonic processes in the eastern North American plate interior, South Anna River, Virginia

We show that long-recognized seismicity in the central Virginia seismic zone (CVSZ) of the eastern North American (ENAM) intraplate setting arises primarily from tectonic processes predicted by new, fully coupled plate tectonic geodynamic models. The study leverages much new geophysical and geologic data following the 2011 Mineral, VA earthquake...

Effect of organic matter concentration and characteristics on mercury mobilization and methylmercury production at an abandoned mine site

Thousands of abandoned mines throughout the western region of North America contain elevated total-mercury (THg) concentrations. Mercury is mobilized from these sites primarily due to erosion of particulate-bound Hg (THg-P). Organic matter-based soil amendments can promote vegetation growth on mine tailings, reducing erosion and subsequent loading...
