CALCULATION METHOD OF REGRESSION FUNCTION FOR FLOW RATE ESTIMATION OF RIVER BASIN IN MOUNTAINOUS DISTRICT, SELECTION METHOD OF THE FUNCTION, AND ANNUAL AVERAGE FLOW RATE ESTIMATION METHOD FOR RIVER BASIN IN MOUNTAINOUS DISTRICT
PROBLEM TO BE SOLVED: To provide an annual average flow rate estimation method capable of efficiently and accurately estimating a flow rate of a river basin in a mountainous district where the flow rate is not measured, by altering a conventional river flow rate estimation method based on a basin ratio.SOLUTION: A basin solid geography correlation area, a basin solid geography correlation altitude, a basin solid depth length, a basin centroid point longitude, a basin centroid point latitude and a basin centroid point altitude in a basin of a water measurement site corresponding to measurements of annual average flow rates in each basin of the water measurement site are calculated and stored in a storage part of a computer. The stored data and a regress function of mathcad (R) that is technical computing software are used to obtain the regress function for estimating an annual average flow rate in the river basin in a mountainous district including at least the basin solid geography correlation area, the basin solid geography correlation altitude, the basin geography depth length, the basin centroid point longitude, the basin centroid point latitude and the basin centroid point altitude in variables, thereby obtaining a regression function for flow rate estimation of the river basin in the mountainous district.SELECTED DRAWING: Figure 1
