These yields are of the same order of magnitude as mean erosion rates back calculated from the volumes of perialpine lake sediment storage, i.e., 1–2 mm yr −1 [Hinderer, 2001], especially when considering that historic Q ś from basins underlain by Bündner schist and flysch is amongst the highest in the Alps.

Landslides as a geomorphological proxy for climate change

Aug 01, 2010 · 1.. IntroductionThe contribution of Geomorphology to paleoclimatic reconstructions is certainly significant. Since morphogenetic processes which take place on the Earth's surface are influenced by climate, landforms as well as superficial deposits potentially provide a record of the evolution of a landscape in a particular climatic framework.

Bistable dynamics between forest removal and landslide

Jan 17, 2014 · Although in this case study, we focus on the effect of forest removal in this region, deforestation has been reported to increase the frequency of landslding worldwide [e.g., Sidle et al., 1985] and thus these results may be extrapolated to other areas susceptible to landsliding following deforestation.

Hydro excavation services use a high pressure water gun and are therefore considered a safer and non destructive digging excavation type. Vacuum excavation uses a suction excavator. It is one of the most effective ways to safely and easily locate underground utilities, mitigating risk to damaging utilities that are already buried.

Landsliding and flooding are closely allied because both are related to precipitation, runoff, and the saturation of ground by water. In addition, debris flows and mudflows usually occur in small, steep stream channels and often are mistaken for floods; in fact, these two events often occur simultaneously in the same area.

Causes, Mechanisms and Prediction of Landsliding in Seattle

Human factors that may have contributed to landsliding were recognized in over 80 percent of the landslides of 1971-1972. Human influences included the diversion of water onto slopes, the steepening of slopes by excavation, the placing of fill on slopes, and the failure of retaining walls.

Apr 02, 2012 · There can be little doubt that the removal of the original indigenous forest cover increased the risk of earth flow initiation and that the absence of a forest canopy and lack of a dense network of intertwining roots in the subsoil is directly related to today's accelerated rates of earth flow movement on pastoral hill country (Marden et al. 1992).

How to Use Cut and Fill Maps to Calculate Cut and Fill

May 19, 2020 · This addition and removal of mass is called cut and fill in the excavation industry. Cut and fill is a common process where the movement of the earth is handled in a logical manner. The goal of cut and fill is ultimately to conserve energy and maximize the use of existing materials to avoid bringing in or shipping out dirt mass.
