Both Clark's synthetic unit hydrograph method and the Extended Kinematic Storage Model are applied to three different steeply sloping watersheds in eastern Kentucky and West Virginia. While both models may be satisfactorily calibrated with the existing data base, only the Extended Kinematic Storage Model was able to survive a series of simple validation tests. The results of this study raise the issue of the universal applicability of the Hortonian runoff process and reinforce the need for operational models which reflect the actual flow mechanisms observed in the field.
