CALCULATION METHOD OF REGRESSION FUNCTION FOR ESTIMATING FLOW RATE OF MOUNTAIN RIVER BASIN, SELECTION METHOD OF THE FUNCTION, AND ANNUAL AVERAGE FLOW RATE ESTIMATION METHOD OF MOUNTAIN RIVER BASIN
PROBLEM TO BE SOLVED: To provide a calculation method of a regression function for estimating a flow rate in which a river flow estimation method by a conventional basin ratio is corrected, and a flow rate of a mountain river with a flow rate unmeasured can be estimated accurately and efficiently.SOLUTION: A calculation method of a regression function for estimating a flow rate of a mountain river basin includes the steps of: calculating an area according to an elevation zone and the elevation according to the elevation zone of an examination river basin, based on a commercial topographic map; calculating a basin solid terrain relative area and a basin relative elevation by using these as input data; and calculating a water estimation flow rate by using mathcad (R) being technical calculation software from a measured value of the annual average flow rate of a flow gaging station basin corresponding to the measured value of the annual average flow rate in each flow gaging station basin, and the calculated solid terrain relative area and the elevation.
