Abstract:

The hydrologic simulation models RUNOFF and HEC-1 are applied to a 3212-ha watershed in New Jersey, and performances of the two models in predicting historical stromwater hydrographs from the watershed are compared. RUNOFF uses an analytical and a shockfitting solutions of the kinematic wave equations, whereas HEC-1 uses a finite difference scheme which has received criticisms in recent times due to its inherent computational error, numerical diffusion and instability. The current study shows that RUNOFF produces similar results as HEC-1 without having these numerical problems, and therefore provides an efficient alternative.
