Abstract

The AA. investigate the influence of rock mass strength on the retreat rate of alpine cliffs. To quantify rockwall competence they employed the Slope Mass Rating (SMR) geomechanical strength index. The study area included a portion of the Sierra Nevada between Yosemite National Park and Lake Tahoe. The AA. found good correlation between rockwall recession rate determined for 40 alpine cliffs and SMR which is best characterized by an exponential decrease in erosion rate with increasing rock mass strength. Analysis of the individual components of the SMR reveals that joint orientation (with respect to the cliff face) is the most important parameter affecting the rockwall erosion rate
