Application of mathematical modeling in rainfall forecast : a case study of Sungai Sarawak basin

Rainfall is a random and probabilistic phenomenon that plays a great role in the life of humans. The study embarks to apply a mathematical modeling in rainfall forecasting for the Sungai Sarawak basin. Recent study reveals that the FS has the ability to simulate long-term rainfa'll up to 300 ye...
