英文摘要: Highways in arid regions are highly exposed to damage by floods. This requires intensive analysis of flood quantity, time and direction that can be used to design the suitable protection measures. Flood hazard mitigation can be achieved through calculating quantities and distribution by deriving a rainfall–run-off relationship which plays an important role in watershed managements and protection. This study aims to determine the overflow stream ways crosswise over roads and their stream sizes under various precipitation events of 10, 25, 50 and 100 return periods. This can be used in the planning of the flood alleviation measures to protect the roads from flood hazards. This methodology is applied to a real area, Tama road as a part of King Abdul-Aziz Highway, Kingdom of Saudi Arabia. Recorded data were gathered for the study area, and hydrological models were used for delineation of the study area. The results indicated that the proposed site of the new road is extremely exposed to flash flood hazard and protection measures are essential to protect the road. A system of protection is proposed and designed including 7 channels and 2 culverts to mitigate the flood hazard in the area of study. The proposed mitigation system is fit for protecting this area from flood hazards. Protection of such roads helps to save lives of people and reduce the cost of maintenance and rehabilitation due to damages caused by flood. © 2020, Springer Nature B.V. Citation statistics:
