Abstract:The present study critically reviews the synthetic unit hydrograph (SUH) methods available in hydrologic literature. The study reveals that the traditional methods of SUH derivation, e.g., Snyder, SCS, traditional methods like Snyder and TS method that does not yield satisfactory results, and their application to the practical engineering problems is tedious and combursome. On the other hand, probability distribution functions (pdfs) based SUH methods are easy to apply, and easily meet the UH criterion, i.e. the area under the curve is unity, and rely on a stronger mathematical base and sounder hydrologic perception. The recent pdfs used for deriving UHs in ungauged catchments, address the SUH shapes with more flexibility than the earlier pdfs proposed by [1] for SUH derivation.

“…Building on this idea, Bhunya et al (2005) developed a hybrid model (HM) for derivation of SUH by splitting the Nash single LR into two serially connected reservoirs of unequal storage coefficients (one hybrid unit) to give a physically realistic response, as shown in Fig. 2.…”
