Rainfall runoff model using probability distributed model (PDM)
Probability Distributed Model (PDM) is widely used in analyzing the hydrological behavior. One of the applications is involved in rainfall runoff modelling to forecast the occuring of flood in Johor Bahru, Malaysia. In this study, Pareto distributed is used to represent the storage capacity of PDM....
