Abstract:An indicator system was established to assess a canal seepage control project based on cost of project, ecological and environmental effect as well as construction technique, thus each seepage control scheme can be evaluated in a scientific manner. As a result, four kinds of canal seepage control schemes in Chuanhang Irrigation District of Suqian in Jiangsu Province were comprehensively eva-luated and the optimum scheme was selected by using a super decision-making software where a multi-attribute decision model, analytic network process and entropy weight fuzzy method were involved. The results showed that the construction technique has the maximum weight, the ecological environment effect has the minimum weight, but the cost of project is in between. The advantages and disadvantages of various seepage control schemes are quite different, namely the relative approximation degree of scheme 1(optimum)is 0.65, then the degree of scheme 4 is 0.37, those of scheme 2 and 3 are in between 0.37 and 0.65. In these assessments the characteristics of canal seepage control in a plain have been presented clearly, and the outcomes are in line with the actual situation of local canals. Obviously, the proposed indicator system can provide a scientific basis for development of canal seepage control project in North Plain of Jiangsu.
