DEFEnS DEbris and Flood Early warNing System

The Waldo Canyon wildfire burned more than 18,000 acres within a perimeter of more than 19,000 acres. In response to the July and August 2013 floods in the Waldo Canyon watershed and in collaboration with the Colorado Department of Transportation (CDOT) and the U.S. Geological Survey developed a warning system for Waldo Canyon associated with a wildfire burn scar, which are at risk to debris...

South Platte Groundwater Analysis

The South Platte River and underlying alluvial aquifer form an important hydrologic resource in northeastern Colorado that provides water to population centers along the Front Range and to agricultural communities across the rural plains. Water is regulated based on seniority of water rights and delivered using a network of administration structures that includes ditches, reservoirs, wells,...

SWOT - Surface Water and Ocean Topography

Satellite altimetry associated with the Surface Water and Ocean Topography (SWOT) mission offers a solution for measuring (1) river stage and slope, (2) water surface area including mean channel width and (3) derivatives such as river discharge. The measurements can be used to track changes in these variables and provide an accounting of the Earth's fresh-water bodies from space at the reach...

Lower Yampa Streamflow and Sediment Modeling

Water from the Yampa River basin continues to be sought for a number of municipal, industrial, and energy uses.  Water development in the Yampa River basin will alter the streamflow regime and, consequently, will lead to changes in the transport and storage of suspended and bedload sediment.  Changes in the Yampa River sediment budget could lead to changes in channel geometry, riparian...

Numerical simulation of groundwater flow in the Lost Creek Designated Groundwater Basin, Weld and Adams Counties, Colorado

The Lost Creek Designated Ground Water Basin (LCDGWB) is an important alluvial aquifer for water supply in northeastern Colorado. Increased demand for withdrawals from the LCDGWB has led to a concern about the long-term sustainability of the basin’s ground-water resources.

A numerical ground-water flow model developed using an early version of MODFLOW exists for the LCDGWB. A review and...

Water budget and potential for underground storage in the Buena Vista-Salida Basin in Chaffee and parts of Fremont, Lake, and Saguache Counties, Colorado, 2009-2012

Population increases in the Upper Arkansas Headwaters Region, which includes Chaffee, Custer, Fremont, and Lake Counties, Colorado, are forecast to increase about 75 percent by 2030.  An annual deficit gap between supply and demand of about 5,950 acre-feet is anticipated.  Groundwater in the area is tributary to the Arkansas River but the effects of additional groundwater use are poorly...

Bandelier National Monument Postwildfire Flood Support

In the summer of 2011, the Las Conchas Fire burned 156,593 acres in the Jemez Mountains in northern NM including the upper watersheds of Frijoles and Capulin Canyons in Bandelier National Monument. The drastic removal of vegetation in the upper watersheds of these popular tourist destinations left them susceptible to dangerous and record breaking floods. As long as the threat of large post-...

Selenium (Se) and salinity (total dissolved solids) are water-quality concerns in much of the arid western US where agricultural and urban irrigation overlie Cretaceous-age shale.  Leaching of Se and salinity from shale can degrade water quality and negatively affect aquatic biota in receiving water bodies. In the upper Colorado River Basin, programs since 1985 have worked to reduce Se and...

Toward ecosystem accounts for Rwanda: Tracking 25 years of change in potential supply and flows of ecosystem services

1.

Anatomy of a caldera collapse: Kīlauea 2018 summit seismicity sequence in high resolution

The 2018 Kīlauea eruption and caldera collapse generated intense cycles of seismicity tied to repeated large seismic (Mw ~5) collapse events associated with magma withdrawal from beneath the summit. To gain insight into the underlying dynamics and aid eruption response, we applied waveform-based earthquake detection and double-difference location...

Relaxing segmentation on the Wasatch Fault Zone: Impact on seismic hazard

The multisegment Wasatch fault zone is a well-studied normal fault in the western United States that has paleoseismic evidence of recurrent Holocene surface-faulting earthquakes. Along the 270-km-long central part of the fault, four primary structural complexities provide possible along-strike limits to these ruptures and form the basis for models...

Holocene rupture history of the central Teton fault at Leigh Lake; Grand Teton National Park, Wyoming

Prominent scarps on Pinedale glacial surfaces along the eastern base of the Teton Range confirm latest Pleistocene to Holocene surface‐faulting earthquakes on the Teton fault, but the timing of these events is only broadly constrained by a single previous paleoseismic study. We excavated two trenches at the Leigh Lake site near the center of the...
