Abstract: Huaihe River basin located in the climate transitional area between the north and south of China, special geographical environment and the mutability and instability of the climate transitional belt result in an uneven distribution of precipitation. As a result, drought and flood disasters occur frequently. The available average water resource per person is about one fifth of the national average; therefore Huaihe basin belongs to an acute water shortage area. The water resources supply and demand contradiction is obvious between Bengbu hydro-junction at main stream of Huaihe River and Hongze Lake during severe water shortage periods. In order to prevent and response emergency water shortage situation, to guarantee the water supply for residents and industries, and to relieve ecological crisis in Hongze lake, water resources emergency plans for the main stream of Huaihe River have been studied. This paper summarized emergency management practice, determined the principles, confines, water resource, routes, low water early-warning index and starting conditions for emergency scheduling. Furthermore, water emergency plans are proposed. This study can provide the scientific proof for water emergency management on main stream of Huaihe River to mitigation drought disaster.
