A DISTRIBUTED APPROACH TO KINEMATIC WAVE MODELING OF WATERSHED SURFACE RUNOFF

In the traditional formulation of kinematic wave theory the kinematic wave friction relationship parameter is treated as constant. While applying the theory to watershed surface runoff modeling the concept of parameter constancy arises the necessity of representing the geometry of a natural watershed as closely as practically feasible in order to minimize the degree of geometric abstraction involved. This approach turns out to be complex and time consuming. Viewing the runoff phenomenon as it is, the proposed study allows spatial variability in the kinematic wave friction relationship parameter and develops a general formation of the kinematic wave theory. This concept results in a completely distributed approach and avoids the necessity of utilizing a complex geometric configuration in the representation of watershed geometry. Furthermore, this approach will reduce the complexity of modeling, and will greatly save the computational time and effort. The usefulness of the proposed approach is demonstrated by its application to modeling surface runoff from a natural watershed.
