Post-fire bedload sediment delivery across spatial scales in the interior western United States

Publications Posted on: November 07, 2016
Post-fire sediment yields can be up to three orders of magnitude greater than sediment yields in unburned forests. Much of the research on post-fire erosion rates has been at small scales (100m2 or less), and post-fire sediment delivery rates across spatial scales have not been quantified in detail.

Science You Can Use Bulletin: Road scholars for the western states: Protecting natural areas by improving road management research

Publications Posted on: April 21, 2016
A poorly placed or unsuitably designed road can result in landslides, flooding, gullies, stream damage, and wildlife habitat destruction. Particularly in natural areas, benefits of roads, such as accessibility and convenience, must be weighed against potential water quality degradation, scenic and wildlife habitat destruction, and hazardous driving conditions.

The 2010 Schultz Fire

The Schultz Fire burned over 15,000 acres of the Coconino National Forest near Flagstaff, Arizona in June 2010.

Spatial variation in spawning habitat of cutthroat trout in a sediment-rich basin

Publications Posted on: May 15, 2015
We examined distribution and habitat characteristics of spawning sites of cutthroat trout Oncorhynchus clarki at various spatial scales to assess effects of sedimentation within a large basin in Montana. Redd density varied widely across the basin; nearly all (99%) of the 362 redds observed occurred in two high-elevation headwater tributaries.

Water quality on forest lands

Projects Posted on: May 13, 2015
This research aims to summarize the state of knowledge regarding the effects of forest management on water quality and the value to society of maintaining high quality runoff from forest lands. Economic costs and benefits of water-quality control was also explored.

Respiratory disease and particulate air pollution in Santiago Chile: Contribution of erosion particles from fine sediments

Publications Posted on: September 30, 2014
Air pollution in Santiago is a serious problem every winter, causing thousands of cases of breathing problems within the population. With more than 6 million people and almost two million vehicles, this large city receives rainfall only during winters. Depending on the frequency of storms, statistics show that every time it rains, air quality improves for a couple of days, followed by extreme levels of air pollution.

Depositional characteristics and sediment availability resulting from the post-Schultz Fire floods of 2010

Publications Posted on: May 09, 2012
Wildfire is a major land management concern due to direct impacts of fire on forest resources, and potentially negative effects on landscape processes by increasing rates of runoff, erosion, downstream sedimentation, and overall site degradation (DeBano et al. 1998, Neary et al. 2005, Robichaud et al. 2010).

Morphology of the Middle Rio Grande from Cochiti Dam to Bernalillo Bridge, New Mexico

Publications Posted on: August 13, 2009
The continuous geomorphologic changes in the Middle Rio Grande in New Mexico have been of interest for many governmental agencies involved with the management and operation of this river system. Due to sedimentation problems along this river, highly developed plans for sediment detention and flood control have been carried out. Cochiti Dam was built as a part of these plans to control floodflows and induce degradation along the main stem.

Hydraulic modeling analysis of the Middle Rio Grande - Escondida Reach, New Mexico

Publications Posted on: August 13, 2009
Human influence on the Middle Rio Grande has resulted in major changes throughout the Middle Rio Grande region in central New Mexico, including problems with erosion and sedimentation. Hydraulic modeling analyses have been performed on the Middle Rio Grande to determine changes in channel morphology and other important parameters. Important changes occurring in the Escondida reach between 1918 and 2005 were analyzed for this study.
