dc.description.abstractThe study explores the suitability of a two-reservoir variable storage coefficient (2VSC) model with respect to the popular two-parameter gamma distribution (2PGD) model (Nash, 1957) for direct runoff hydrograph (DRH) derivation from a small test catchment. The proposed model is based on the concept of VSC that utilizes a varying storage coefficient K (by ratio r) instead of a uniform storage coefficient K as in the 2PGD model. Further, the proposed model uses unit-step rainfall instead of unit-impulse as input. The results show the 2PGD model to respond faster to a given amount of input (excess rainfall) than the 2VSC model. Based on the results it is found that the 2VSC model performs significantly better than the 2PGD model in deriving the shape of the direct runoff hydrograph. However, for a comparatively larger catchment the 2PGD model performs better than the 2VSC model. Similar to the 2PGD model, the 2VSC model has potential for synthetic unit hydrograph derivation.
