Due to the absence of the reasonable allocation and management of flood drainage right, most of the people consider their own interests when the floods occurred, which exacerbated the flood loss and caused water dispute. Taking the midstream of Huaihe River as the example, this study try to solve the flood problems from the reasonable allocation of flood drainage right. We analyzed the drainage conditions, discussed the generalized physical model and dynamic coordination model structure. The dynamic and balanced model for the reasonable allocation of flood drainage right was established with the flood disater losses minimum as the objecetive funciton and flood risk as the important constraint, which will provide the scientific basis to study the reasonable allocation of flood drainage right and serve the project layout, integrated management and flood control. © (2013) Trans Tech Publications, Switzerland.

Using main ditch for farmland drainage is a basic measure to solve waterlogging problem in Huaibei Plain of Auhui Province. However, uncontrolled drainage often results in serious waste of water resources. In the present study, we established two experimental zones (Bazhang Ditch, Chezhe Ditch) with the total area 218km2. Based on the field observations combined with theoretical simulation analysis, the key techniques were studied systematically such as the effect of main ditch control projects on farmland drainage, groundwater depth, rainfall-runoff and groundwater resources regulation in the two zones. The results show that the controlled drainage of main ditch could regulate groundwater depth and increase the groundwater utilization, improving farmland ecological environment and regulating water resources allocation in time and space. In addition, it didn't influence the farmland drainage. This technique has been widely applied in Huaibei Plain and achieved good social, economic and environmental benefits. It can be used as a reference for the construction of control drainage project and regulation of farmland water resources in similar areas.
