This study uses curve fitting techniques to formulate a model for the flow of water in Awara River in Ondo State. The model is formulated to reflect the interrelationship existing among the discharge of water, distance the water travels for a particular time range of continuous rainfall and the velocity of the flow of the water and the average rainfall. These are terms considered significant in predicting the distance covered by flooding at a particular time. A direct runoff generation using average rainfall on a yearly basis for the years (1985 – 2005), giving a total of 21 years was used to formulate the model. It was observed that the peak distance covered by the flood occurs in the month of September and the model takes the form of, 5 5 1.78*10 ( ) 21.63*10 S R Where: S is the distance covered by the flood in metre and R is the monthly average rainfall in millimeter
