Geohydrologic conditions on a steep forested slope : modeling transient piezometric response to precipitation

Creator:

Bransom, Mark

Abstract:

Two hilislope sites in the central Oregon Coast Range were instrumented and monitored for winter precipitation and saturated and unsaturated subsurface conditions. The study sites were near-ridge depressions typically known as headwalls. Based on results of the monitoring, two existing mathematical models were adapted to predict piezometric levels in headwalls...

Dissertation
Simplified stability assessment for low volume road cut and fill slopes

Creator:

Pratt, Randy C.

Abstract:

Many miles of roads are built in the Pacific Northwest Forests to provide access for logging and fire protection. Logging roads often cross steep mountainous terrain. Logging roads and the associated cut and fill slopes represent a discontinuity in the natural stress state in the soil mantle. These conditions result...
