Description :
The pattern of relative denudation at the soil-bedrock interface over a wooded Magnesian Limestone hillslope was investigated using microweight loss bedrock tablets. The resulting pattern of weight loss after emplacement for one year indicated a consistent upslope increase in solutional denudation. Dye tracing and gypsum sphere weight loss results showed that water movement over the slope was by vertical percolation and not by throughflow. Comparison with a similar study suggests that a general soil chemistry based model of hillslope solutional denudation can be proposed.
