Fig. 10. Output from a PALMS model run simulating a 28.2-mm rainfall runoff event on a 3.7-ha field near Saukville, WI (grid cells shown are 5 by 5 m; topography is exaggerated 14x; north is to the left in the figure). (a) Net erosion for the entire runoff event. Darker shades are net erosion; lighter shades are net deposition. Values range from –4.28 kg cell^–1 (deposition) to 0.25 kg cell^–1 (erosion). The position of the runoff and sediment collector is shown with an asterisk. (b) Number of rills per cell formed by this runoff event.
