Precipitation and Streamgage Flood Warning System

Rainfall amounts associated with the September 2013 Colorado Floods exceeded 15 inches in some locations and resulted in significant flooding along the Front Range (Hydrometeorological Design Studies Center, 2013). These events resulted in streamflows that compromised a variety of transportation structures such as bridges and culverts and roadways.

By coupling the National Oceanic and...

Lower Gunnison River Basin - Gunnison River Synoptic

In response to the need for more information about selenium (Se) sources and transport, the U.S. Geological Survey, in cooperation with the Colorado Water Conservation Board, completed a study that characterized Se loads in a reach of the Gunnison River between Delta and Grand Junction, Colo.

This study identifies where possible dissolved Se loading is occurring in a study reach in the...

Selenium on Sediment in Lower Gunnison River Basin Critical Habitat

The Gunnison Basin Selenium Management Program (SMP) implemented a water-quality monitoring network in 2011 in the lower Gunnison River Basin in Colorado. Selenium (Se) is a trace element that bioaccumulates in aquatic food chains and can cause reproductive failure, deformities, and other harmful effects.

The dissolved concentration of selenium in the water column is not necessarily a...

Potentiometric Surfaces and Groundwater-Level Changes

In the past, groundwater pumped from the Santa Fe Group aquifer system was the principal source of water for the Albuquerque metropolitan area of central New Mexico. The large quantity of groundwater pumping relative to recharge resulted in substantial drawdown in the aquifer system. In 2008 the Albuquerque Bernalillo County Water Utility Authority began diverting water from the San Juan-Chama...

Changes in Watershed Hydrologic Response Time with Post-wildfire Changes in Vegetation and Surface Fuels Along a Severely-burned, High-desert Canyon, Bandelier National Monument, NM

Flash flooding can be a destructive and life-threatening response of watersheds to intense rainfall events, particularly in sparsely­ vegetated, or burned watersheds. Studies have been conducted to estimate the magnitude of hydrologic responses of burned watersheds to rainfall events, however the time that it takes a flood to travel through a burned watershed and reach a critical or populated...

Post-Wildfire Investigation: Analysis of Soil Properties Based on Burn Severity

The Las Conchas fire started on June 26, 2011, near the small community of Las Conchas in the Jemez Mountains of north-central New Mexico. When the fire was contained on August 3, 2011, it had burned 156,593 acres of mixed conifer, pinyon/juniper and ponderosa forest and at the time was the largest wildfire in New Mexico history. Peak burn severity was extreme; over 60,000 acres of the total...

Streamgaging: Silent Sentinels

Streamflow data are needed at many sites on a daily basis for forecasting flow extremes, making water-management decisions, assessing current water availability, managing water quality, and meeting legal requirements. These activities require streamflow information at a given location for a specified time. These needs generally are best satisfied by operating a station to produce a continuous...

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...

Classification of oil spill by thicknesses using multiple remote sensors

Satellite Synthetic Aperture Radar (SAR) is an operational tool for monitoring and assessment of oil spills. Satellite SAR has primarily been used to detect the presence/absence of oil, yet its ability to discriminate oil emulsions within a detected oil slick has not been fully exploited. Additionally, one of the challenges in the past has been...
