Description

To establish a better drainage planning by pump in paddy field, inquiries were made as to 60 districts all over the country. The results obtained are as follows :
(1) In all districts, the pump capacity is in the range of 1-5mm/hr.
(2) In all districts, the actual pump head is in the range of 0.5-0.6m.
(3) The basic rainfall used for drainage planning in most districts is a three-day one.
(4) Generally, the optimal capacity of drainage pump is yet unsolved.
