This data set is the runoff and sediment observation data set of qiaozigou watershed in the third sub region of the Loess Hilly and gully region from 1990 to 1999. 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.

Artificial timing observation
Manual observation is carried out by professional and technical personnel; four levels of manual verification are carried out in the process of data input, which are tabulation, initial calibration, re calibration and audit, so as to ensure the data quality.
