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.

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...

Dust deposited on snow cover in the San Juan Mountains, Colorado, 2011-2016: Compositional variability bearing on snow-melt effects

Light-absorbing particles in atmospheric dust deposited on snow cover (dust-on-snow, DOS) diminish albedo and accelerate the timing and rate of snow melt. Identification of these particles and their effects are relevant to snow-radiation modeling and thus water-resource management. Laboratory-measured reflectance of DOS samples from the San Juan...

Assessing population-level consequences of anthropogenic stressors for terrestrial wildlife

Human activity influences wildlife. However, the ecological and conservation significances of these influences are difficult to predict and depend on their population‐level consequences. This difficulty arises partly because of information gaps, and partly because the data on stressors are usually collected in a count‐based manner (e.g., number of...

Evidence for late Quaternary deformation along Crowley's Ridge, New Madrid seismic zone

The New Madrid seismic zone has been the source of multiple major (M ~7.0–7.5) earthquakes in the past 2 ka, yet the surface expression of recent deformation remains ambiguous. Crowleys Ridge, a linear ridge trending north‐south for 300+ km through the Mississippi Embayment, has been interpreted as either a fault‐bounded uplift or a nontectonic...

Testing glacial isostatic adjustment models of last-interglacial sea level history in the Bahamas and Bermuda

Part of the spatial variation in the apparent sea-level record of the last interglacial (LIG) period is due to the diverse response of coastlines to glacial isostatic adjustment (GIA) processes, particularly where coastlines were close to the Laurentide Ice Sheet during the past two glacial periods. We tested modeled LIG paleo-sea levels on New...

Evaluation of soil zone processes and a novel radiocarbon correction approach for groundwater with mixed sources

Estimates of groundwater age based on 14C is often limited by the uncertainty in geochemical processes that alter the 14C concentration measured in water and the composition (δ13C and 14C) of carbon sources needed to appropriately parametrize 14C adjustment models. Estimated ages for samples that contain a mixture of young and old groundwater will...

Runoff sensitivity to snow depletion curve representation within a continental scale hydrologic model

The spatial variability of snow water equivalent (SWE) can exert a strong influence on the timing and magnitude of snowmelt delivery to a watershed. Therefore, the representation of subgrid or subwatershed snow variability in hydrologic models is important for accurately simulating snowmelt dynamics and runoff response. The U.S. Geological Survey...
