Bahat et al. () indicated a lumped model performed better than a distributed model in a rainfall-runoff modeling study of a small, hyper-arid catchment in Israel. But the Yixunhe River sub-basin is very large and heterogeneous, so a set of model parameters cannot reflect the non-uniformity of the watershed characteristics, which degrades Cited by: alternative parameter quantification approach based on the phys-ical attributes of a basin. It addresses the question of whether physical basin properties and the role they play in runoff gen-eration can be used directly in the estimation of parameter val-ues.

Abstract The paper presents a modification of a rainfall–runoff parameter regionalization procedure, which can be used for model parameter estimation in ungauged basins. The upper Hron River basin in Slovakia was selected as a study area. Data from 19 sub-catchments were collected and a lumpedFile Size: KB. are problems to build and calibrate a rainfall-runoff model, because it depends on the characteristics of the river basin. One of daily rainfall-runoff model (used for this study) is GR4J (Genie Rural a 4 parametres Journalier) which was developed by Perrin [9] and was proven having strong basic and efficient in a modeling.

A comprehensive hydrological model, like the storm water management model (SWMM), has been widely used for rainfall-runoff simulation. In recent years, simple and effective modern modeling techniques have also brought great attention to the prediction of runoff with rainfall input.
