Chemical Modeling of Acid Waters Questa Baseline and Pre-Mining Ground-Water Quality Investigation, Red River Valley Basin, New Mexico

The US Geological Survey and the New Mexico Environment Department entered into a Joint Powers Agreement as of April 30, 2001 to execute an investigation of baseline and pre-mining ground-water quality in the Red River Basin, New Mexico. The main objective is to infer the pre-mining ground-water quality at the Questa Molycorp mine site. This study was formulated because New Mexico law states...

Comprehensive Water-Quality Study for the Arkansas River Basin, Colorado

Changes in land and water use associated with population growth and agricultural practices within the Arkansas River Basin are likely to affect water-quality on a local and, possibly, a basin-wide scale. To manage the limited water resources in the basin most effectively it is important to understand the processes that affect water quality within the basin and how future changes in land and...

Chemical Modeling of Consequences of Surface-Water Delivery Through Existing City of Albuquerque Infrastructure

The City of Albuquerque has historically obtained all of its municipal-supply water from production wells completed in sediment of the Santa Fe Group aquifer system. Like several communities in the Rio Grande Valley and various parts of the arid Southwest, Albuquerque has evaluated the use of surface water as a means to improve sustainability of its municipal water supply. The City currently...

Aquatic communities and associated water chemistry in the St. Vrain River near the City of Longmont wastewater-treatment plant

The St. Vrain River watershed in northeastern Colorado has experienced rapid urban growth over the last two decades. Population growth has led to increased volumes being treated at wastewater-treatment plants (WWTPs) in the basin. In the last two decades, in-stream restoration efforts and new treatment technologies have been implemented by the City of Longmont, with the goal of improving water...

RCMAP - Lake Fork at Gateview, Colorado

The U.S. Geological Survey was engaged in a program to monitor and assess the long-term geomorphic behavior of selected river and stream reaches that previously had undergone some physical modification.  These modifications included natural channel adjustments to floods as well as intentional channel reconfigurations to alter the function or appearance of a river reach.

Floods Analysis

Accurate estimations of flood discharges at bridge or culvert sites is required to provide cost-effective design of that structure. Streamflow-gaging stations, for which flood data are available, are usually located in major perennial drainage basins that are not representative of sites where common bridge and culvert designs are needed.

In 1942, the USGS, in cooperation with the New...

Rio Grande Travel Times

The City of Albuquerque will begin accepting delivery of imported San Juan-Chama water to supplement present municipal water supplies as part of the City's Drinking Water Project (DWP). The City's San Juan-Chama water will be diverted from the Rio Grande near Alameda Bridge in Albuquerque, transported to a treatment facility, and eventually distributed to customers.

Numerical simulation of the cumulative effects of land-use change and aggregate mines on ground-water flow and wetlands along the South Platte River, Brighton to Fort Lupton, Colorado

The South Platte River valley between the City of Brighton in Adams County and the town of Fort Lupton in Weld County, Colorado, contains many wetland areas that provide habitat for wildlife in the Front Range Urban Corridor. The extent of aggregate mining along this reach of the South Platte River valley continues to increase as the demand for aggregate grows in response to urban development...

Fault fictions: Systematic biases in the conceptualization of fault-zone architecture

Mental models are a human's internal representation of the real world and have an important role in the way we understand and reason about uncertainties, explore potential options and make decisions. Mental models have not yet received much attention in geosciences, yet systematic biases can affect any geological investigation: from how the...

Instrumental ground‐motion recordings from the 2018 Anchorage, Alaska (⁠Mw">Mw 7.1), earthquake sequence provide an independent data set allowing us to evaluate the predictive power of ground‐motion models (GMMs) for intraslab earthquakes associated with the Alaska subduction zone. In this study, we evaluate 15 candidate GMMs using...

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...

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...
