APPLICATION OF FLOOD FLOW ROUTING AS A PRIDICTIVE MODEL FOR FLOOD MANAGEMENT AND CONTROL

A critical review of some recorded cases of flooding, coupled with the analysis of the causes and effects of flood on properties and human population was done. The major focus of the research paper is to evaluate the necessary control measures needed to deal with issues of flooding and the associated disaster. The center point of the research paper was the use of reservoir for flood control involving the construction of different sizes of dams depending on the flow velocity of the river thus creating a storage reservoir at the river upstream which allowed the water to be stored during periods of heavy runoff and released during dry season. Time dependent data which include the inflow and the out flow into a specific river having a dam was collated. The data were then model using the Muskingum equation for flood flow routing in order to determine the routing period which is a direct indication of the released time that will allow for maximum storage at the upstream section, thereby helping to check excessive flood at the downstream section of the river.
