Criteria and Method on Regional Floodwater Utilization Competitiveness Assessment

The concept of regional floodwater utilization competitiveness is demonstrated from the forming properties of floodwater and characteristic of floodwater utilization techniques. The criteria on sustainableness, systematization, safety, effectiveness and equity, as well as the related evaluating index, are set up for regional floodwater utilization competitiveness assessment. Based on the efficiency coefficient method, the competitiveness assessment model is proposed, and an improved efficiency coefficient method is employed in which efficiency coefficient function is defined as non-linear normal membership function. The proposed model and computing procedure is applied to evaluate competitiveness of floodwater utilization in Bei-san-he basin, Haihe River Basin. The assessment result shows there are higher competitiveness of floodwater utilization in plain sub-regions, but there is lower competitiveness in mountainous sub-regions.
