The runoff and sediment amount during runoff generation are calculated by water level observation and sediment sampling at runoff station. The data set includes the measured discharge results of Qiaozi Donggou and Qiaozi xigougou calibre flow stations, the extract table of flood hydrological elements, the successive flood test results, the daily average discharge table, the daily average sediment concentration table and the daily average suspended sediment transport rate table. &amp;lt;/p&amp;gt;\n</code></pre>",

When there is little water, the flow is measured by the volume method with the connecting tube, and the flow is calculated by the buoy method for the flood. In flood, straw is used as a buoy, while wood chips and sorghum poles are used as buoys in normal water. The buoy coefficients are not calibrated, and they are all 0.85. The observation time of runoff station is generally twice at 8:00 and 20:00 every day. In flood period, the observation times are increased according to the water regime, generally 5-10 times a day, and 20-40 times for some large floods.</li>\n<li>Sediment concentration observation: sampling by water side one point method. The number of sampling is basically the same as that of current measurement. Sometimes, the sampling frequency is increased appropriately to control the change of sediment concentration. The filtration method is usually used for sand sample treatment.</li>\n</ol>",
