River Basin Erosion Dynamics

Experimental Approach Goals Determine long-term (~1,000 - 50,000 yr) average erosion rate Assess contemporary rates of erosion Determine what factors drive erosion . • Tectonic and lithologic controls Slope, rainfall, channel steepness, etc. Agriculture vs. Forest Tools In situ 10Be • Meteoric 10Be Excess 210Pb 137Cs Sediment Yield • Topographic analysis of DEM'S ● Analysis of land-use data Field observations
