Slope Erosion and Mass Movement in Relation to Weathering in Geochemical Cycles

Abstract

Geomorphic models of slope development and hydrologic models of runoff generation are reviewed in order to identify the major processes of interest. Slope erosion and mass movement are then classified and typical rates of operation identified. Rates of weathering are also reviewed. The main purpose of the chapter is to identify the sediment and solute budget approach as the best way to understand the relative roles of slope erosion, mass movement and weathering in relation to geochemical cycles. Major problems that have been encountered in the quantification of sediment and solute budgets are discussed.
