Abstract: In this paper, the basic single area unit hydrograph model is shown to represent a highly complex, rational, link-node model which includes (i) variable effective rainfall distributions over each subarea, including variations in distribution magnitude, timing, and storm pattern shape; (ii) variations in the subarea runoff response on a storm class basis; (iii) variations in channel flow routing response on a storm class basis, including peak attenuation and translation timing effects.
