A Simple Method of Decision for the Design Flow Rate of Fish Way
Proceedings of the International Symposium on Fishways '95
The Organizing Committee for International Symposium on Fishways '95 in Gifu
Flow rate data were analyzed to propose a simple method for deciding about the design flow rate of a fishway. The analyzed flow rate data were obtained at gauge stations distributed all over Japan, for approximately 33 years, on average. The main results are as follows: (1) the 185-day discharge is comparatively correlative to the discharge area; (2) the n-day discharge is strongly correlative to the 185-day discharge except for a large flood occasion; (3) the fluctuation range of flow rate, available for deciding about the design flow rate of a fishway, can be calculated by the discharge area only.
