Abstract:

Floods have caused noticeable damages in floodplains every year. An important issue in regions with construction sites such as diversion dams is how to protect the project during construction. In the implementation of flood management schemes, both non-structural and structural options should be considered. Experience shows that nonstructural options are more effective than structural methods in reducing flood damages at a lower cost. In this paper, an algorithm is developed to define a management scheme for flood protection. An economic analysis is undertaken which combines the analysis of probable floods and the expected damages for different flood control options as well as a simple flood warning system. The case study is the Shirgovaz diversion dam which is located 44 kilometers downstream of the Pishin dam in South Baloochestan in southeastern Iran. In 1984 and 1995 the diversion dam experienced heavy damages due to significant floods in the river. The results show that considering a flood warning system for cases such as the set up of the Pishin dam and its diversion dam is an effective method to reduce flood damages. This type of system could provide early warning to the main dam and to the downstream area. A simple flood warning system has been designed and could utilize the information that is obtained from the upstream synoptic and hydrometric stations.
