Error Experiment Analysis on Lanzhou Hydrologic Station Flow Inspection of Yellow River

Make the middle or small scale uncertainty experiment analysis is very important for guiding to survey the flow and improving the survey accuracy in this area. So, we choose Lanzhou hydrologic station to do the experiment and analyze the width ＆deepth error and I, II, III error. Do the uncertainty analysis on different schemes of two-points flow survey in this station at the same time.
