Abstract:In order to reduce the disaster loss which caused by levee-breach flood, it is very important to quickly and accurately forecast the inundated range and the effects of flood receding measures in the emergency disposal. Taking the emergency analysis for the Luobei inundated area in Heilongjiang Province as the example, for the target of moving back of the transferred people, this paper introduced how to quickly build a numerical model, design reasonable simulation schemes and analyze the flood receding effects. The results show that the flood can be receded when the water level of the outer river falls. However, the target of flood receding can 't be achieved only by the levee-breach and escape gate. In order to solve the resettlement problem in the freezing period, it is very necessary to add a man-made outlet for receding flood. There is little difference of the flood receding effects with different size of man-made outlet. The width should not be too large considering the quantity of plugging the outlet.
