Risks exist in any waterlogging control project due to the random features of natural disasters.The optimization for the regional design criteria for waterlogging control is put forward in this paper based on risk analysis of waterlog losses

and by minimizing the sum of the engineering cost and the super standard waterlog losses as the objective function.In this optimization model

the functional relationship is established between waterlog risks

engineering cost

super standard waterlog losses and decision variable by taking the drainage design criterion P as the decision variable

on the basis of which the design criterion for waterlogging control is optimized.The practical application of the optimization method indicate that the optimized results may be in closer agreement with the regional features and eliminates the arbitray selection of design criterion.
