Modelling root reinforcement in shallow forest soils

Creator:

Skaugset, Arne E.

Abstract:

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 soil strength and increases the risk of management -induced landslides. The technical literature does not adequately support...

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...
