Analysis of Assessment System of Irrigation Infrastructure Based on Asset Management Approach

It is clear that improving management of infrastructures in irrigation district will contribute to a higher level of water resources management.In this paper,Asset Management Approach,which originated in the commercial and financial field,is introduced to management process of irrigation infrastructure.According to the main principle of Asset Management Approach,a comprehensive assessment system of irrigation infrastructure asset is suggested to assess three major kinds of factors: hydraulic performance,condition and importance.The analytic hierarchy process and entropy method are applied in this model to affect factor's weight.The assessment results are supportive for administrator to identity priority for asset renewals.A case study of the Fourth Second Main Canal of Zhanghe Irrigation District,Hubei Province is showed.The analysis results about regulator,culvert,elevated aqueducts,bridge and pumping station reflect the actual performance and level of service in Zhanghe Irrigation District.
