Abstract

The first part of this article is dedicated to the magnitude-frequency approach, which represents a new light in Process Geomorphology assessment. Its proposal remounts to Wolman and Miller’s work (1960), but gained a new force with the Ahnert’s paper (1987), which integrates in a semilogarithm function the amount of effective contribution of a variety of events considered in a processes study. This approach is indistinctly applicable in all work scales and for all kinds of events, providing more accurate predictions in time and space. The second part refers to the evolution of models for slope stability, created in Soil Mechanics and adapted to Geomorphology, from Coulomb (1776) to Fredlund (1987). Surveyed data examples in a humid tropical area are presented in the two parts to illustrate the assertions and comments.
