| Abstract: | Objective] To study the design methods of water-saving irrigation engineering,so as to improve the water retention rate of conservation facilities and the utilization rate of irrigation water.Method] The suitability of various channel systems was analyzed,the common ladder type and U-type open channel conveyance systems were optimized and then verified with a case study of the land consolidation project in Banzhuang Town of Ganyu County in Jiangsu Province.Result] The U-type concrete channel was made according to local soil conditions,the roughness of channel bed was 0.015,a mathematical model was optimized;the decision variable was longitudinal slope =1/2 000,camber angle =5°;the best channel section which costed the least was obtained,the total investment of this channel was 37 806 Yuan.Conclusion] The designed scheme is practical. |
