This paper stresses the dynamic nature of runoff-contributing areas and their relationship to the geomorphological structure of catchments. Example calculations show that both runoff and flood frequency predictions may be very sensitive to assumptions about the nature of the contributing area. An extension of the Beven-Kirkby model is proposed to predict variable contributing areas. The results presented are sufficiently encouraging to suggest that the improved model is worthy of further study.
