设计基于径流回收的灌溉系统以在季风季节为水稻提供灌溉是一个复杂的问题。灌溉需求以及径流形式的可用水量和时间都各不相同。根据短期实验获得的灌溉需求来设计灌溉系统可能会导致设计错误。为了克服这个问题，对种植区和水箱的水平衡进行了模拟研究，以确定五年重现期的集水指挥面积比和水箱尺寸。研究发现，为了在最佳时期进行移栽，集水控制比应为5.0或以上，并且储水池容量为132.6毫米，对于U.P.来说，在5年的回报期下就足够了。印度的中山。还发现短期品种更适合这种灌溉系统。
Design of a runoff-recycling-based irrigation system to provide irrigation for rice in monsoon season is a complex problem. The irrigation requirement, as well as the water availability in the form of runoff, vary both in amount and time. The design of an irrigation system based on the irrigation requirement obtained from short-period experiments may lead to faulty design. To overcome this, a simulation study of water balance of the cropped area as well as the tank has been done to determine the catchment command area ratio and size of the tank for a five year return period. It has been found that for transplanting within optimum period, the catchment command ratio should be 5.0 or more and a tank of storage capacity of 132.6 mm will be sufficient at a return period of five years for the U.P. midhills of India. It has also been found that a short-duration variety will be more suitable for such an irrigation system.
