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 (mm/kyr) 250 200 150 100 50 Erosion Rate (mm/kyr) 0 10 60 110 160 210 Channel Steepness 250 200 150 100 50 0 10 15 20 Hillslope Angle 25 25
