Computation of optimum realizable unit hydrographs

Abstract

The Wiener‐Hopf theory of optimum linear systems is applied to the determination of the stable pulse response of a monotone hydrologic system from coincident records of input and output in the form of discrete time series. In application to the rainfall runoff system, linear programming methods are used in the solution of the Wiener‐Hopf equations to obtain physically realizable unit hydrographs.
