Abstract

This study is based on a literature survey. It shows that the amplitude of relief is the dominant factor to be considered for ranking erosion rates. Extreme figures of 50 and 500 mm per 1,000 years are therefore proposed as mean values of erosion rates, respectively for plains, hills and mountains, for indurated rocks and for non-periglacial climates. Coefficients must correct these values when dealing with softer rocks or periglacial climates. All these factors are liable to change as functions of the surface areas of the morphological units considered.
