| The research estimated the roughness coefficients for the reach of Hwawon-Goryeonggyo-Hyeongpung stage stations in the Nakdong River through hydraulic channel routing. The data needed were only stage data from the three stations and river cross section data. Stage-discharge relations were determined from the computed discharges by the channel routing. They are better than the previous stage-discharge relations from direct measurements. Discharge computation errors from stage errors were analyzed and a simple method was suggested to limt reach lengths from prohibiting large errors from lateral inflows. |
