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...

Detrital zircon geochronology along a structural transect across the Kahiltna assemblage in the western Alaska Range: Implications for emplacement of the Alexander-Wrangellia-Peninsular terrane against North America

The Kahiltna assemblage in the western Alaska Range consists of deformed Upper Jurassic and Cretaceous clastic strata that lie between the Alexander-Wrangellia-Peninsular (AWP) terrane to the south, and the Farewell and other peri-cratonic terranes to the north. Differences in detrital zircon populations and sandstone petrography allow geographic...

Mountain-block recharge: A review of current understanding

Mountain-block recharge (MBR) is the subsurface inflow of groundwater to lowland aquifers from adjacent mountains. MBR can be a major component of recharge but remains difficult to characterize and quantify due to limited hydrogeologic, climatic, and other data in the mountain block and at the mountain front. The number of MBR-related studies has...

Permeability anisotropy and relative permeability in sediments from the National Gas Hydrate Program Expedition 02, offshore India

Gas and water permeability through hydrate-bearing sediments essentially governs the economic feasibility of gas production from gas hydrate deposits. Characterizing a reservoir’s permeability can be difficult because even collocated permeability measurements can vary by 4-5 orders of magnitude, due partly to differences between how various...
