Performance assessment of wood strand erosion control materials among varying slopes, soil textures, and cover amounts

Publications Posted on: February 27, 2020
Two blends of manufactured wood strands with different lengths were tested for effectiveness in controlling erosion. Wood strand blends were tested on two soils, two slopes, and at three coverage amounts. Laboratory rainfall simulations were conducted to evaluate runoff and sediment loss. Wood strands were effective in delaying runoff, reducing runoff volume, and reducing sediment loss.

The fusion of discontinuous gullies

Publications Posted on: February 05, 2020
This case study demonstrates the fusion of two discontinuous gullies in the Colorado Front Range and relates storms and flows to the erosion events. In 7 years, only 5 storms produced runoff in a gully system in the Colorado Front Range of the Rocky Mountains. Storm intensities for periods of 10 minutes influenced runoff production; antecedent precipitation was of no benefit to forecast gully flows.

Managing vegetation to increase flow in the Colorado River Basin

Publications Posted on: July 31, 2019
Water yield from forest and rangelands can be augmented by managing vegetation and snow to reduce evapotranspiration. Some arbitrary goals to increase water yield were chosen to illustrate the potential for increasing water yield, and treatments were hypothesized to get these increases.

Effectiveness of road ripping in restoring infiltration capacity of forest roads

Documents and Media Posted on: November 30, 2018
 Many forest roads are being closed as a step in watershed restoration. Ripping roads with subsoilers or rock rippers is a common practice to increase the infiltration capacity of roads prior to closure. When considering the effectiveness of ripping for reducing runoff and erosion and the potential reduction in slope stability by saturating road fills, it is important to know how ripping changes the infiltration capacity of forest roads.Document Type: Other Documents

2016 High Park fire science workshop

Projects Posted on: May 17, 2017
A workshop was hosted by the Coalition for the Poudre River Watershed for those interested in wildfires and post-fire ecology and impacts, discussing transmission of key research findings from work done in the High Park Fire on key topics, implications for post fire restoration management decision making and identification of barriers to rehab/restoration action & knowledge gaps. Researchers from Rocky Mountain Research Station, CSU, and other regional institutions presented results from their work since the High Park Fire.

This web site displays some of the past and current fire-related activities of the Southwest Watershed Science Team of the RMRS Air, Water, Aquatic Ecosystems Program.

Rill erosion in burned and salvage logged western montane forests: Effects of logging equipment type, traffic level, and slash treatment

Publications Posted on: November 07, 2016
Following wildfires, forest managers often consider salvage logging burned trees to recover monetary value of timber, reduce fuel loads, or to meet other objectives. Relatively little is known about the cumulative hydrologic effects of wildfire and subsequent timber harvest using logging equipment.

Ecohydrologic impacts of rangeland fire on runoff and erosion: A literature synthesis

Publications Posted on: August 16, 2016
Fire can dramatically influence rangeland hydrology and erosion by altering ecohydrologic relationships. This synthesis presents an ecohydrologic perspective on the effects of fire on rangeland runoff and erosion through a review of scientific literature spanning many decades.

Incorporating hydrologic data and ecohydrologic relationships into ecological site descriptions

Publications Posted on: June 24, 2016
The purpose of this paper is to recommend a framework and methodology for incorporating hydrologic data and ecohydrologic relationships in Ecological Site Descriptions (ESDs) and thereby enhance the utility of ESDs for assessing rangelands and guiding resilience-based management strategies.

Structural and functional connectivity as a driver of hillslope erosion following disturbance

Publications Posted on: June 24, 2016
Hydrologic response to rainfall on fragmented or burnt hillslopes is strongly influenced by the ensuing connectivity of runoff and erosion processes. Yet cross-scale process connectivity is seldom evaluated in field studies owing to scale limitations in experimental design.
