An investigation of the influence of root reinforcements on soil strength and the initiation of static liquefaction in forest soils

Creator:

Smith, Russell S.

Abstract:

A study was conducted to investigate the influence of root reinforcements on soil strength and the initiation of static liquefaction in forest soils. The design and operation was developed of an apparatus capable of modeling rainfall-induced shallow hill-slope failures that also permitted observation of the soil volume change tendencies at...

Peakflow causative mechanisms and frequencies at Reynolds Creek, southwestern Idaho

Creator:

Kirkham, Tracie

Abstract:

Peakflow frequency analysis is used in forest hydrology for designing stream crossing structures such as culverts and bridges. The traditional approach to frequency analysis is based on the assumption that the observed sample of peakflows represents a homogeneous population. It is not clear if using the "homogeneous" population of the...

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...

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...
