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...

Mechanical stresses in trees resulting from strain compatibility in an anisotropic material

Creator:

Lyons, Charles Kevin

Abstract:

Consider the bole of a tree to consist of a linear elastic material that is orthotropic with respect to the cylindrical coordinates. When the bole of a tree is subjected to resultant loads in the directions of the Cartesian base vectors, the S₁₁, S₂₂, S₃₃, and S₁₂ stresses in Cartesian...

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...

Reducing sediment production from forest roads during wet-weather use

Creator:

Toman, Elizabeth Myers

Abstract:

Forest roads produce fine sediment with traffic during wet weather. If the forest road is connected to a stream it can be a source of turbidity and fine sediment that may be detrimental to aquatic organisms especially salmonids. The goal of this work was to investigate turbid runoff during wet-weather...
