Investigations of runoff production and sedimentation on forest roads

Creator:

Wemple, Beverley C.

Abstract:

Forest roads constructed in steep mountain landscapes have been associated with a number of effects on hydrologic and geomorphic processes. This research examined the effects of forest roads on the flow of water and sediment in drainage basins in the Cascade range of western Oregon. A study conducted at the...

Determinants of microbial community structure and substrate utilization potential in soils of vegetable cropping systems

Creator:

Schutter, Mary E.

Abstract:

The Oregon Long-Term Soil Quality Project was initiated to identify soil properties that respond rapidly to alternative management practices. Such practices included winter cover cropping, which was implemented at two experimental research stations and several grower fields throughout the Willamette Valley. The goal of this thesis was to identify the...

Processes that influence the downstream propagation of heat in streams below clearcut harvest units : Hinkle Creek paired watershed study

Creator:

Otis, Timothy Leonard

Abstract:

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 of the Cascade Mountains about 30 kilometers northeast of Roseburg, Oregon, is privately owned, and supports...
