Measuring low rates of erosion from forest fuel reduction operations

Publications Posted on: March 24, 2015
A study was carried out to evaluate three methods for measuring low levels of hillside soil erosion associated with forest fuel management activities, and to measure erosion from cable logging and skid trails. The tipping bucket device with a sediment basin appears to be a better tool for this application than silt fences or rillmeter analysis.

Forest biomass utilization and watershed processes

Documents and Media Posted on: January 23, 2015
Forest biomass is an energy source that is underutilized. Expanding forest biomass utilization can improve our nation's energy security while reducing greenhouse gas emissions from fossil fuels. However, there is a risk that water resources may be adversely affected with increased biomass removal. Our research aims to assist land managers to evaluate watershed impacts of biomass removal.Document Type: Briefing Papers

Soil erosion and sediment production on watershed landscapes: Processes and control

Publications Posted on: September 30, 2014
Losses of the soil resources from otherwise productive and well functioning watersheds is often a recurring problem confronting hydrologists and watershed managers. These losses of soil have both on-site and off-site effects on the watershed impacted.

Great Lakes WEPP Watershed

Tools Posted on: August 05, 2014
The Water Erosion Prediction Project (WEPP) is a computer simulation that predicts soil erosion.  This particular version of the tool predicts soil erosion for the Great Lakes watershed.

Geospatial application of the Water Erosion Prediction Project (WEPP) model

Publications Posted on: June 28, 2013
At the hillslope profile and/or field scale, a simple Windows graphical user interface (GUI) is available to easily specify the slope, soil, and management inputs for application of the USDA Water Erosion Prediction Project (WEPP) model. Likewise, basic small watershed configurations of a few hillslopes and channels can be created and simulated with this GUI.

Seasonal change of WEPP erodibility parameters for two fallow plots on a palouse silt loam

Publications Posted on: June 28, 2013
In cold regions, frozen soil has a significant influence on runoff and water erosion. In the U.S. Inland Pacific Northwest, major erosion events typically occur during winter as frozen soil thaws and exhibits low cohesion.

Current research issues related to post-wildfire runoff and erosion processes

Publications Posted on: June 28, 2013
Research into post-wildfire effects began in the United Statesmore than 70 years ago and only later extended to other parts of the world. Post-wildfire responses are typically transient, episodic, variable in space and time, dependent on thresholds, and involve multiple processes measured by different methods.

Post-fire rill and gully formation, Schultz Fire 2010, Arizona, USA

Publications Posted on: February 05, 2013
The Schultz Fire burned 6100 ha on the eastern slopes of the San Francisco Peaks in northern Arizona. The fire burned between June 20th and 30th, 2010, across moderate to very steep ponderosa pine and mixed conifer watersheds. About 40% of the fire area was classified as high-severity, mostly on mountain slopes greater than 30% and in places exceeding 100%.

Post-fire rill and gully formation, Schultz Fire 2010, Arizona, USA

Publications Posted on: September 14, 2012
The Schultz Fire burned 6,100 ha on the eastern slopes of the San Francisco Peaks, a dormant Middle Pliocene to Holocene aged stratovolcano in northern Arizona (Figure 1). The fire burned in the Coconino National Forest between June 20th and 30th, 2010, across moderate to very steep ponderosa pine and mixed conifer watersheds.

Geomorphic aspects of post-fire soil erosion - Schultz Fire 2010

Publications Posted on: September 14, 2012
The summer of 2010 brought wildfires and near record monsoon rains to northern Arizona, USA, which generated debris flows and floods that caused extensive damage. The human-caused Schultz Fire on the Coconino National Forest northeast of Flagstaff was the largest wildfire in Arizona during 2010, burning 6,100 ha between June 20th and 30th.
