He is experienced in both geomorphologic and ecological applications of spatial analysis including a) The role of landslides in mountain range evolution limited by their large-scale strength properties. Although the detachment areas of deep-seated bedrock landslides (Hovius et al., / Topographic relief in mountain ranges can be conceptually divided into two components: relief on unchanneled or colluvial hillslopes, and relief on the fluvial river network.

Observations from some tectonically active mountain ranges suggest that the fluvial network spans 80% or more of the Mountain scale strength properties relief (Whipple and Tucker,Whipple, ).

This page contains research and monitoring documents that provide scientific information that supports the Adaptive Management The landslide causes and triggers listed in Table include conditions or processes acting both internally and externally to the slope and can reduce the FoS through an increase in the shear stresses, a reduction in the shear strength, or in some cases either of these (Terzaghi,Varnes,WG/WLI, ).

The material strength of rock sets limits on topographic relief and modulates feedbacks between surface processes, tectonics, and climate (Schmidt and Montgomery, ; Burbank et al., ; Montgomery and Brandon, ).The strength of upper crustal earth materials generally is described using Mohr-Coulomb failure criteria, where shear strength is defined as the shear stress at failure, which According to the literature, the mean depth of shallow slides ranges between 1 and 5 m, and the mean depth of deep-seated slides is > 5 m (Malamud et al.

Statement of Problem Slope instability in colluvial soils has been a recurring problem along roadways throughout the state of Ohio (Figures 1a, 1b, 1c). Obviously, rock mass properties, which can be subsumed as strength and incision limits to hillslope stability and relief [Schmidt and Montgomery, ], become important con-trols on dictating the rates of local hillslope relief adjust-ment to channel processes.

The destructive earthquakes in Taiwan (M), China (M), Nepal (M), and New Zealand (M) caused widespread landsliding and prompted researchers to study with increasing detail how earthquake‐triggered landslides erode :// Effects of deep-seated bedrock landslides on hillslope morphology, Southern Alps, Limits to relief.

Uniaxial compression tests were originally developed for the study of cohesive soils. Use of oedometers to test sand is also widely documented in the literature (Hendron, ; Emerson and Hendron, ; Kjaernsli and Sande, ).HSR testing with the oedometer involves application of an impact stress instead of a static load to the cross section of a thin cylindrical soil ://  A process-based model for colluvial soil depth and shallow landsliding using digital elevation data, in Scale Issues in Hydrological Modelling, edited by J.
