  • Bibliography ; Computing ; Digital elevation model ; Model ; Research ; Slope ; Slope dynamics ; Slope gradient ; Soil ; Soil properties ; Years 1990-99
  • This particular time period has seen considerable wide-ranging advances in slope research. There has been an almost complete turnaround in the approach taken towards slope research. Two linked themes provide the principal focus for this article
  • . First, recognition of the importance of differentiated soil profiles (and vegetation) to slope development that has underpinned much recent research. Secondly, the development of computational techniques that has enabled such research to be promoted
  • , as both larger (long-term slope development) and smaller (detailed soil profile hydrology) scales can be tackled using state-of-the-art hardware and software.
  • Factors affecting sedimentary outflow from talus slope by debris flow : a laboratory experiment
  • Alluvial cone ; Cliff ; Debris flow ; Experimentation ; Japan ; Precipitation ; Sediment transport ; Slope ; Slope dynamics ; Slope gradient
  • To examine running distance of debris flows occurring on the talus slopes, rainfall experiments were carried out. The quantity Vt is defined as the reciprocal of the threshold value of Lc/Lt at which debris flows just reach the bottom of the talus
  • slope, where Lc is the horizontal length of the cliff and Lt is the horizontal length of the talus slope. The value of Vt is also a measure of the possibility of sedimentary outflow from the talus slope by debris flow. The value of Vt shows strong
  • correlation with the hydraulic conductivity of talus sediment (K) and the rainfall intensity (It). The outflow of debris from the talus slope can be predicted using the values of Lc, Lt, K, and It.

  • Mass movement ; Model ; Porosity ; Slope ; Slope dynamics ; Soil properties
  • The A. presents a new two-dimensional statical model to examine the mechanism of stability of slopes composed of granular materials. The model, named GSM, is based on the static equilibrium among particles, in which static equilibrium of each
