Abstract: Floods are still a problem to many countries in the world todate. Floods do cause damage to property and sometimes loss to human life. Flood control measures by structural and non-structural methods are available in the literature. However, structural flood control measures are financially infeasible in most developing countries today. Flood forecasting is a non-structural measure for reducing flood damages. It is a means of providing early flood warnings to flood prone areas. The linear Perturbation Model has been applied for real time flood forecasting in Tanzanian catchments. The Linear Perturbation Model in an updated mode performed better in five catchments and can be used for real time flood forecasting in such catchments.
