Description :
Eight runoff plots, located within a small catchment within the Walnut Gulch Experimental Watershed, southern Arizona, were consructed to test the argument that sediment yield decreases as plot length increases. Runoff and sediment loss from these plots were obtained for 10 natural storm events. Analysis of both runoff and sediment yield from the plots indicates that the relationship of sediment yield to plot length derives both from the limited travel distance of individual entrained particles and from a decline in runoff coefficient as plot length increases.
