Present, past and potential denudation rates : is there a link? Tentative evidence from fission-track analysis in the South Indian shield

Description :
This study seeks to explore the value of Ahnert equation as a normative geomorphological tool. In 2 successive and complementary stages, its principles are applied to the Western Dharwar Craton of South India. First, the robustness of local relief as a reliable substitute for mean slope is examined. Observed similarities between long-term, short-term and potential denudation rates are used as a basis for assessing the potential of Ahnert's index as a possible standard in the appraisal of measured denudation values, and for evaluating the impact of man-induced erosion in the crystalline uplands of South India.
