Middle Rio Grande Basin Study

The U.S. Geological Survey (USGS) Middle Rio Grande Basin Study was a 6-year effort (1995-2001) by the USGS and other agencies to improve the understanding of the hydrology, geology, and land-surface characteristics of the Middle Rio Grande Basin in order to provide the scientific information needed for water-resources management. The Santa Fe Group aquifer system is the main source of...

Water, Energy, and Biogeochemical Budgets (WEBB): Loch Vale Watershed

Loch Vale is an alpine/subalpine watershed in Rocky Mountain National Park where the U.S. Geological Survey has been conducting research since the 1980s. Our research has focused on the effects of climate change and atmospheric pollutants on water, soil, vegetation, and aquatic life. The alpine/subalpine ecosystem in Loch Vale is sensitive to changes in climate and air pollution. Our long-term...

Comparison of the power consumption coefficient (PCC) method to totalizing flow meter (TFM) for estimating ground-water pumpage in the Arkansas River Valley, Colorado

In the mid-1990s, the Colorado Division of Water Resources (CDWR) adopted rules governing measurement of tributary groundwater pumpage for the Arkansas River Basin. The rules allowed groundwater pumpage to be determined using one of two approaches—power conversion coefficient (PCC) or totalizing flowmeters (TFM). In addition, the rules allowed a PCC to be applied to the electrical power usage...

Hydrogeology and water quality of the shallow unconsolidated-rock aquifers in the Upper Arkansas River Basin from Buena Vista to Salida, Colorado

Population growth near Buena Vista and Salida in Chaffee County has caused concern for the long-term availability and quality of groundwater . Groundwater withdrawals from deep wells that are completed in the basin-fill deposits and designed to supply multiple-dwelling developments could cause drawdowns in water levels of the overlying aquifers. Continued development of groundwater supplies in...

Stochastic Modeling of Effects that the Sulphur Gulch Reservoir May Have on Colorado River Water Quality near Grand Junction, Colorado

Sulphur Gulch, a new reservoir proposed to be located about 25 miles east of Grand Junction, Colorado, on a tributary to the Colorado River that drains the Sulphur Gulch watershed between De Beque and Cameo, Colorado. The primary use of the Sulphur Gulch Reservoir would be to provide the Colorado River with up to 5,412.5 acre-feet of late-season water in support of the Endangered Fish Recovery...

Sources of Metal Loading to the Lake Fork from Turquoise Lake to the confluence with the Arkansas River

The Lake Fork emerges from the outlet of Turquoise Lake at the Sugarloaf dam and flows approximately 5 miles before joining the upper Arkansas River. The first reach of the Lake Fork downstream from the dam is affected by drainage from abandoned mines in the Sugarloaf mining district. Whereas remediation of some of the mine sites has been initiated, Federal Land holders are interested in...

Types and areal distribution of ground failure associated with the 2019 Ridgecrest, California, earthquake sequence

The July 2019 Ridgecrest, California, earthquake sequence included the largest earthquake (M 7.1) to strike the conterminous United States in the past 20 yr. To characterize the types, numbers, and areal distributions of different types of ground failure (landslides, liquefaction, and ground cracking), I conducted a field investigation...

The future of landslides’ past—A framework for assessing consecutive landsliding systems

Landslides often happen where they have already occurred in the past. The potential of landslides to reduce or enhance conditions for further landsliding has long been recognized and has often been reported, but the mechanisms and spatial and temporal scales of these processes have previously received little specific attention. Despite a...

Risk-targeted alternatives to deterministic ground motion caps in U.S. seismic provisions

Since their inception over 20 years ago, the maximum considered earthquake ground motion maps in U.S. building codes have capped probabilistic values with deterministic ground motions from characteristic earthquakes on known active faults. This practice has increasingly been called into question both because of spatially non-uniform risk levels...

Exploring regional scale metamorphic fabrics in the Yukon Tanana terrane and environs using quantitative domain analyses

Metamorphic rock fabrics such as foliations and lineations provide a rock record of numerous deformational characteristics in the Earth’s crust. When spatial information is combined with fabric data collected at points on geologic maps, the nature and consistency of metamorphic fabrics can be explored through structural domain analysis. This is...

Bayesian modeling of non-stationary, univariate, spatial data for the Earth sciences

Some Earth science data, such as geochemical measurements of element concentrations, are non-stationary—the mean and the standard deviation vary spatially. It is important to estimate the spatial variations in both statistics because such information is indicative of geological and other Earth processes. To this end, an estimation method is...
