Understanding change of drainage in rotational paddy basin is important. On the other hand, dif f usive tank model is simpler than unsteady flow model,moreover, its simulation computer time can reduce. When simulate the drainage of low-lying basin, it shows a good coincidence. In this paper using the model account for above adv antages. This paper, first, explores the situation of drain age in rotational paddy farm; second, introduce the compendium of diffusive tank model.Finally, givingdesign storm then using the diffusive tank model simulatethe change of runoff according to rotational paddyfarm in basin and analyzesensitivity of parameterin model. Because the cases of farm are complicate,so in this paper just consider large-scale rotational farm for simplifying case. According to the resul ts of study can evaluate area of dry-land and planning discharge in basin, farther, support the reference of project and design of defensive construction and drainage system.
