受自然条件变化或渠内流量改变的影响，自然界或水利工程中大多数明渠水流属于非恒定流。传统的排洪沟道设计方法以恒定流理论为基础，对于一些复杂情况，其计算结果常与实际不符，无法满足设计要求，应用受到较大限制。通过分析渠道设计理论应用现状，以广东省韶关市乳源县白竹村农田排水工程改造设计方案为例，采用基于非恒定流理论的MIKE11水动力学模型（HD）对排洪沟道进行设计，并通过成果对比分析证明了该方法的可行性与优越性。

Due to the changes in natural conditions or discharge of canals ,a large proportion of open-canal flow in natural world or wa‐ter conservancy projects belongs to unsteady flow .However ,the traditional methods of designing drainage ditches calculate briefly with the theory of open-canal steady flow .For some complex situations ,the results do not always agree with the actual conditions . As the results cannot meet designing requirements ,its application is very limited .By analyzing the application status of ditches de‐sign theory ,an example of the cropland drainage engineering transformation scheme ,designed in Baizhu Village of Luoyang Town , Ruyuan County ,Shaoguan City ,Guangdong Province ,is given in this paper .MIKE11 hydrodynamic module (HD) is used to design the drainage ditches based on the theory of unsteady flow .The new method has proved its feasibility and superiority through a com‐parative analysis of results .
