| 内容記述 | In designing a sewage system the determination of flood discharge is the first requisite. Therefore, it is important to select and use the right rainfall intensity formula which fit well for the weather condition in the area concerned. The purpose of this study is to test the usefullness of some of popular rainfall intensity formulas when applied in Okinawa Islands. The formulas considered herein are those presented by A.N.Talbot, C.W.Sherman, and S. Hisano. The weather records used in this study were collected from the weather bureaus in three cities, that is,Naha (Okinawa Is.), Hirara(MiyakoIs.), and Ishigaki(Yaeyama Is.). From the discussion presented in this paper it was found that Talbot formula, expressed as I=a/(t+b), is more suitable for weather condition in Naha and Hirara, whereas Hisano'sformula, I=a/(√<t>-b), was found suitable in Ishigaki. In these formulas the letter 1 means rainfall intensity in millimetre per hour, t the duration of rainfall in minute, and a, b are constants. The values of the constants were determined from the weather data in those three cities for specified frequency of occurence, say, 1,2,.....n year storm. It is also found that five year storm frequency are more preferable to use in the formulas as a standard in all of these cities. The constants a and b in this case were determined as 9280 and 62, respectively for Naha, 5590 and 49 for Hirara, and 674 and -1.3 for Ishigaki. | |||||||||
