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.

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...

The influence of frequency and duration of seismic ground motion on the size of triggered landslides—A regional view

Observation, theory, and intuition all suggest that larger earthquakes should trigger larger landslides. Many factors could contribute to this, including depth-dependent shear strength or non-linearity of ground motion in soils and rock, but we hypothesize that the key characteristics of large earthquakes causing this phenomenon are (in addition...

Isolating anthropogenic wetland loss by concurrently tracking inundation and land cover disturbance across the Mid-Atlantic Region, U.S.

Global trends in wetland degradation and loss have created an urgency to monitor wetland extent, as well as track the distribution and causes of wetland loss. Satellite imagery can be used to monitor wetlands over time, but few efforts have attempted to distinguish anthropogenic wetland loss from climate-driven variability in wetland extent. We...

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