Abstract：According to the characteristics of floodwater utilization measures in the semi arid and semi humid area,the principle and method of calculation of flood-control risk are described for reservoir operation,flood detention areas employ?ment and canal storages regulation. On the basis of using grade of risk and grade of risk importance to evaluate flood risk from floodwater utilization of sub-regions and various utilizing measures,the model,which can consider the fuzzy property of flood risk assessment,is proposed for evaluating the aggregative risk of floodwater utilization based on Fuzzy mathemat?ics and Analytic Hierarchy Process(AHP). And the hierarchical structure and solving procedures of the model are de?tailed. Finally,taking the Gaotang-Ahu Irrigation District in Xuzhou,Jiangsu Province as example,the aggregative risk rate is computed using the proposed model for evaluating risk in the regional floodwater utilization.
