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

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.

Assessing impacts of fire and post-fire on runoff and erosion from rangelands mitigation

Publications Posted on: June 24, 2016
To provide an overview of the immediate and short-term hydrologic impacts of fire on infiltration, runoff, and erosion by water, and of the effectiveness of various mitigation treatments in the reduction of runoff and erosion in the years following the fire.

Streamside management zones

Pages Posted on: December 28, 2015
Streamside management zones are special landscape units that include riparian areas and adjacent lands that mitigate the movement of sediment, nutrients, and other chemicals from upland forest and agricultural management areas into streams.

Depositional characteristics of post-fire flooding following the Schultz Fire, San Francisco Peaks, Arizona

Publications Posted on: September 14, 2012
During the summer of 2010 the northern Arizona mountain town of Flagstaff experienced three fires all blazing the same week in late-June, the height of the fire season for this region. By July 1st, all three were extinguished, but that was only the first phase of disturbance. The largest and most detrimental of these fires was the Schultz Fire.

Soil water repellency and infiltration in coarse-textured soils of burned and unburned sagebrush ecosystems

Publications Posted on: April 30, 2009
Millions of dollars are spent each year in the United States to mitigate the effects of wildfires and reduce the risk of flash floods and debris flows. Research from forested, chaparral, and rangeland communities indicate that severe wildfires can cause significant increases in soil water repellency resulting in increased runoff and erosion.

Fire effects on rangeland hydrology and erosion in a steep sagebrush-dominated landscape

Publications Posted on: April 30, 2009
Post-fire runoff and erosion from wildlands has been well researched, but few studies have researched the degree of control exerted by fire on rangeland hydrology and erosion processes. Furthermore, the spatial continuity and temporal persistence of wildfire impacts on rangeland hydrology and erosion are not well understood.

Infiltration, erosion, and vegetation recovery following road obliteration

Publications Posted on: March 05, 2009
Forest roads are obliterated to lower the risks of surface erosion and mass failures. One purpose of the road obliteration is to return the compacted forest roads to productive pre-road conditions, i.e., a forest floor with high infiltration capacity, low interrill erodibility, and high vegetation ground cover. It is important to know how these characteristics recover following road obliteration.
