Planning and operation of dams

Abstract

The water discharged from a dam during operation must not cause floods downstream. Especially, if there is a large subcatchment area downstream and if surface runoff water due to rainfall cannot to be controlled, there is a considerable risk of flood downstream. Under these circumstances, the additive water coming from the reservoir will cause an increase in the flood damages. In this paper, the flood risks of rainfall water discharge from the subcatchment area, which is located in the downstream area of a dam and not completely controlled have been investigated. For this purpose, the decision matrix achieved from the rainfall of subcatchment, which lies between the Porsuk dam and Eskişehir city, was examined by taking the Porsuk subcatchment as a basis
