Two experimental fields have been selected for a runoff research. One is located at Yaka, Kincho which excel Kunigami Maaji soil and the other is located at Senbaru, Nishihara-cho which excel Jaagaru soil. The crops cultivated in the two fields are pineapple in Yaka field and sugar cane in Senbaru field. The watershed area of the two fields are about 4000m^2 and 10000m^2 respectively. The results of the investigation are as follows. 1. If a rain storm comes to a half for 1 to 2 hours in case of Yaka field and for 2 to 3 hours in case of Senbaru field, the following rain storm may be regarded as separated one for the runoff analysis. 2. The relationships between rainfall and runoff coefficient of the two fields are illustrated in Figs. 8 (Yaka field) and 9 (Senbaru field) and are also expressed by the following equations. f=1.0-1.347R^<-0.390> (Yaka field) f=1.0-3.162R^<-0.593> (Senbaru field) where f is runoff coefficient and R is rainfall in millimeters. 3. Runoff factors obtained in this investigation at Yaka field are effective rainfall, water losses and peak runoff as well as rainfall itself. The relationships between rainfall and effective rainfall, water losses and peak runoff are expressed by the following equation. The relationships between rainfall and effective rainfall and water losses are also illustrated in Figs 10 and 12,respectively. r_e=R-1.347R^<0.610> r_l=1.347R^<0.610> Q_p=0.979R_<10> where r_e is effective rainfall in mm., r_l is water losses in mm., Q_p is peak runoff in cubic meter per 5min., R_<10> is max. 10min. rainfall intensity and is rainfall in mm..","subitem_description_type":"Other"},{"subitem_description":"\u7d00\u8981\u8ad6\u6587","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/4057"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0370-4246"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250548"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8\u5b66\u8853\u5831\u544a"},{"subitem_1522650068558":"en","subitem_1522650091861":"The Science Bulletin of the Faculty of Agriculture.
