Effects of Overbank Flow in Flood Computations
The derivation and application of unsteady free surface flow equations are presented which describe floods in rivers where dynamic effects are considered in both the main channel as well as berm or overbank sections of the flood plain. Literature to date considers overbank portions of a river significant only for purposes of storage. Such an assumption is not always justified. The equations are used to describe flood conditions that occurred in 1970 in the Bicol River Basin in South Luzon, Philippines. The dynamic effects of the flow in the berms is determined by comparing the computed river stages and discharges considering conditions with and without the dynamic effects of the berm flow.
