Sediment and runoff collected from skidder biomass reduction plots, Deception Creek Experimental Forest, Idaho

Datasets Posted on: December 30, 2020
This investigation looked at the Sands Creek timber sale within the northern Idaho Deception Creek Experimental Forest (DCEF). The Sands Creek timber sale is approximately 46 hectares (113 acres), and is located roughly 40 kilometers (25 miles) east/northeast of Coeur d’Alene, Idaho. Seven hillslope tipping bucket runoff plots were installed in Unit 1 of DCEF, near the southwestern corner of the timber sale.

Measurements of low rates of erosion from forest fuel reduction operations in the Clearwater National Forest, Idaho

Datasets Posted on: December 30, 2020
The Yellowpine biomass reduction study was installed on the Clearwater National Forest approximately 5 miles northeast of Harvard, Idaho. The study site was part of the Yellowpine timber sale that was harvested in the spring of 2002 followed the next year by a prescribed burn in September of 2003. This study includes 3 units: 1, 4, and 5.

Validation of the Unit Stream Power Erosion and Deposition (USPED) Model at Fort Hood, Texas

Publications Posted on: December 11, 2020
Soil erosion has been recognized as a significant environmental malady in the United States for over 200 years. Numerous attempts have been made to model and quantify the issue, yet significant issues remain that hinder the accuracy and effectiveness of such models.

Post-wildfire moss colonization and soil functional enhancement in forests of the southwestern USA

Publications Posted on: October 02, 2020
Fire mosses, including Ceratodon purpureus, Funaria hygrometrica and Bryum argenteum, can achieve high cover within months to years after high-severity fire, but do so heterogeneously across space and time. We conducted a survey of moss cover and erosion-related functions after 10 wildfires in Pinus ponderosa and mixed-conifer forests of the southwestern USA.

Application of the unit stream power erosion and deposition model at Eglin Air Force Base, Florida

Publications Posted on: June 10, 2020
Soil erosion is a serious phenomenon which can be accelerated beyond sustainable levels by anthropogenic activities such as military training. Soil erosion modeling can be utilized in an effort to identify accelerated erosion and concomitant sedimentation before they reach unsustainable levels. Regrettably, most models are deficient in the way they account for topographic heterogeneity.

Fire effects on soil erosion and deposition on hillslopes in the oak savannas

Publications Posted on: March 12, 2020
Fire was a natural occurrence in many ecosystems of the Southwest Borderlands before Euro-American settlement. However, natural fire frequencies and the burning characteristics of the fires have been altered since the early 1900s, largely because of past livestock grazing practices, which removed significant portions of the fire-carrying herbaceous vegetation, and past fire suppression policies of land management agencies (Edminster et al.

Validation of the Unit Stream Power Erosion and Deposition (USPED) Model at Yakima Training Center, Washington

Publications Posted on: September 14, 2019
During the last seventy years, numerous models have been developed to predict soil erosion; some models also predict concomitant sediment deposition. All have been proven inadequate and/or inaccurate in one respect or another. This paper discusses the application of the new-generation Unit Stream Power Erosion and Deposition (USPED) model at the US Army’s Yakima Training Center (YTC), Washington.

From watersheds to the web: Online tools for modeling forest soil erosion

Pages Posted on: April 05, 2018
Forest erosion can lead to topsoil loss, and also to damaging deposits of sediment in aquatic ecosystems. For this reason, forest managers must be able to estimate the erosion potential of both planned management activities and catastrophic events, in order to decide where to use limited funds to focus erosion control efforts. To meet this need, scientists from RMRS (and collaborators) have spent over a decade developing a suite of online tools that can be used to predict erosion potential of forest alterations such as road building, forest management, and wildfire, as part of the Forest Service-Water Erosion Prediction Project (FS-WEPP). FS-WEPP is being continually refined, improved, and expanded upon to increase its usefulness, and to enable managers to run predictive watershed models for better land management decision-making and more desirable outcomes.

Impact of surface coal mining on soil hydraulic properties

Publications Posted on: January 06, 2017
Soil erosion is strongly related to soil hydraulic properties. Understanding how surface coal mining affects these properties is therefore important in developing effective management practices to control erosion during reclamation.

Development of online tools to support GIS watershed analyses

Publications Posted on: January 06, 2017
In 1996 there was a meeting in Tucson of hydrologists from every Forest Service region, as well as Forest Service research scientists engaged in watershed-related activities. This meeting was organized by the Stream Team (which has since been enveloped by the National Stream and Aquatic Ecology Center). The focus of the meeting was to identify tools that needed to be developed to support watershed management.
