Description :
Recent publications from field and simulation studies indicate that runoff per unit area decreases as the length of the slope being observed is increased. This paper presents the design and testing of a laboratory flume for the study of the processes that lead to this scale effect, particularly for the case of slopes covered with crops. The features of the flume include reliable experimental control of soil water content prior to rainfall, high intensity rainfall without erosion, uniform crop growth along the slope, and the option of varying the infiltration rate indepently of rainfall and soil characteristics.
