Abstract :本文は特性係数法によって沖縄地方7地点の短時間降雨強度をTalbot型, Sherman型, 久野型の3式型について算出し, 各地でのそれぞれの式型の適合度を調べ, 最適式型を決定した。それらの結果は那覇 : Talbot型 石垣島 : Sherman型 宮古島 : 久野型 久米島 : Sherman型 与那国島 : Talbot型 南大東島 : Talbot型 名護 : Sherman型となる。
The purpose of this stude is to calculated probable rainfall by Specific coefficient method, and to tost the usefullness of three popular rainfall intensity formulas at 7 points in Okinawa Islands, those three formulas are Talbot's, Sherman's and Hisano's. It was found that Talbot's formula, I=a'/(t+b), is fit for Naha, Yonagunizima and Minamidaitozima. Sherman's formula, I=a'/t^n, was fitted for Ishigakizima, Kumezima and Nago and Hisano's formula, I=a'/√<t>+b, was fitted for Miyakozima, where I is rainfall intensity (mm/hr), a, b, n are constants.
