River Basin Erosion Dynamics

Controls of erosion in basin 35 Base level fall is primary control on long- and short-term erosion Slope steepness determines long-term erosion rate Erosion Rate 210Pb Activity ex 35 4.02 Bq/kg 0 4 km Erosion rates increase after channels steepen and hillslopes respond Contemporary erosion. appears to be controlled by un-measured variable(s) 4.82 Bq/kg 2.87 Bq/kg
