Mathematical Models of Water Yield with Particular Reference to Mississippi Watersheds: Interim Report Number 1. A Study of Some Empirical Methods of Determining the Unit Hydrograph

摘要

An attempt was made to evaluate, compare and rank nine different methods of deriving the unit hydrograph (UH) on a small agricultural watershed, which included (1) matrix methods, (2) transform methods, (3) time series methods, and (4) linear programming methods. Although the matrix methods, except for the least squares method, yield exact solution for the UH, these methods are not suitable for deriving the representative UH for a given watershed. However, transform, time series and linear programming methods can be used as effective tools in the UH derivation.
