Overland flow is a primary factor in channel initiation where saturation overland flow deepens to increase shear stress and begin channel incision.[1] Overland flows converge in topographical depressions where channel initiation begins. Soil composition, vegetation, precipitation, and topography dictate the amount and rate of overland flow. The composition of a soil determines how quickly saturation occurs and cohesive strength retards the entrainment of material from overland flows.[1] Vegetation slows infiltration rates during precipitation events and plant roots anchor soil on hillslopes.[1]
