A FLOOD CONTROL OF DAM RESERVOIR BY CONJUGATE GRADIENT AND FINITE ELEMENT METHODS

Flood control of dam reservoir by the combined method of conjugate gradient and finite element methods is presented. For the numerical integration procedure, the two step explicit scheme originally presented by the authors' group was effectively used. Using the numerical computation based on an imaginary river basin and estimated hydrograph, it is seen that the water elevation can be controlled by the discharge of the dam gate to obtain an almost flat water surface. It was found that the flow rate of the dam gate should discharge in advance before the peak value of the flood arrives to control the wave propagation caused by the sudden close of the dam gate. This paper presents the strategy for operating the dam gate knowing the flood configuration beforehand.
