Interception of precipitation by forest canopies has been found previously to reduce rainfall intensity, but this effect is poorly understood. The goal of this research is to quantify the attenuation of rainfall intens ...

Shallow, translational landslides occur naturally and are the dominant form of erosion in the Pacific Northwest and the Oregon Coast Range. These landslides are triggered during large, infrequent storms. Forest managemen ...

A one-mile section of a newly constructed forest road in Northwest Oregon was analyzed for various aspects of subgrade and surface strength and their association with the formation of ruts during the first hauling season ...

The management of existing forest road systems is an issue of growing importance and public debate. Roads can alter the hydrologic processes in a watershed especially at stream crossing culverts where road ditches chann ...

The increased demand for wood and fiber from a continually shrinking land base has resulted in the use of intensively managed forest plantations. The concentration of timber production on the most suitable sites allows t ...

A hypothesis used to explain the relationship between timber harvesting and landslides is that tree roots add mechanical support to soil, thus increasing soil strength. Upon harvest, the tree roots decay which reduces ...

This research investigates the direct and downstream impacts of clearcut harvest units on stream temperature as a part of the Hinkle Creek Paired Watershed Study. The Hinkle Creek watershed is located in the foothills ...
