Abstract: Most of the cross-section form of the natural river channel is irregular and the stage-discharge curve (h~Q curve) is higher-order implicit function which causes the difficulties in deriving curve directly. In this study, the sectional form was determined by crossing section measurement, and the flow area corre- sponding to the different water depth was estimated by number of grid which was inserted in the adopted cross-section. The parameters used in calculation were calibrated through leveling survey and experiment, an
