Abstract

The Huaihe River Basin is a transitional river located in the transitional climate zone in China, and it has been frequently hit by big floods and suffered from flood disasters. Flood control and management of the areas are of vital importance of the Huaihe River Basin in its social and economic development. In this paper, pioneer works of summarizing the flood management has been done for the Huaihe River in China. It firstly introduces flood and flood disasters of the River basin, Moreover, the paper summarizes achievements in flood control and management. Furthermore, it discusses experiences and enlightenment in flood control and management and draws conclusions for the research.

5. Achievements in Flood Control

5.1. Experiences in flood management

Flood disaster, which occurred suddenly and inevitablely, is different from the general emergency disasters. It is determined by the natural conditions of the Huaihe Basin. By review of the Huaihe River flood regulation, it is found that the keys of success are still dependent on the following factors:

(1) The complete flood control structural system is the foundation of flood regulation and management.

The standard and quality of the flood control works are directly related to flood management and projects operation. Although the standard of the flood control system in Huaihe Basin is not high enough, it is compounded by a wide range of works with high correlation. Their operation is very flexible, especially the flood regulation of detention basins and diversion channels like Huaihongxinhe canal and Ruhaishuidao canal (floodway to the sea), plays a vital role in flood control. In future we should strengthen the construction of structural system for flood prevention and increase the flood control standard appropriately.

(2) Accurate hydrologic forecasting is the prerequisite of the flood regulation.

The forecast accuracy and the lead time will directly affect the correctness and timeliness of the flood regulation decision. In recent years, the extreme weather events have increased significantly from global perspective. The sudden strong rainfall is unforeseeable, and it becomes a new issue for flood prevention work. In the future, we should continue to strengthen early warning system, to optimize flood forecasting model and to improve forecast accuracy and quality. Particularly, there is an urgent call for constructing an ensemble flood forecasting system integrating with numerical weather models, distributed hydrologic models, hydraulic models and real-time control models.
