Application of SCS Curve Number Method for Irrigate Paddy Field

다국어 초록 (Multilingual Abstract)

The runoff curve number (CN) for irrigated, level-terraced paddy fields was estimated from measured rainfall and runof data. TheCN values were determined from the maximum retention storages at probabilities of 10, 50, and 90%, from a fitted lognormaldistribution. The CN values at the antecedent moisture condition (AMC) I, II, and III were found to be 67, 82, and 91, respectively.Flooding depths and the heights of check gates were also monitored to work out the hydrologic characteristics for pady fields. Thefield data showed flooding depth seem to be a major factor affecting retention storage. Thus, flooding depth in paddy fieldscorresponding 10, 50 and 90% probabilities were consider to be equivalent to AMC I, I, and AMC III, respectively.
