ABSTRACT
Short-term rainfall forecasts have commonly been made using Quantitative Precipitation Forecasting (QPF). The introduction of QPF in flood warning systems has been recognized to play a fundamental role. The prediction or forecast of natural disasters is critically important for emergency management workers. An aim of forecasting is to gain adequate time to evacuate people from disaster zones, to minimize loss of life, and reduce damage to structures and infrastructure, and minimize economic loss. Small watersheds have short time of concentration and reaching its peak, the response time of smaller basins could be on the order of a few hours or less than one hour. The rainfall forecast is an important component of the flood alert system that is designed to collect, handle, analyze and distribute information for the purpose of providing advanced warning of a flood condition. This is possible when there is a good stochastic rainfall prediction, and a good hydrological model.
