Datasets description

This data set is the runoff and sediment observation data of xindiangou watershed test site from 1980 to 1990. Through the water level observation and sediment sampling of runoff station section, the runoff and sediment amount during runoff generation are calculated. The data set includes flow section diagram of runoff station, measured discharge result table, extraction table of flood hydrological elements, successive flood test result table, daily average discharge table, daily average sediment concentration table and daily average sediment transport rate table. See the basic information table of runoff stations in xindiangou basin for the situation of runoff stations.

Data source description

Manual timing observation

Data processing method

1. The water level observation method of runoff station is: read the water gauge number of the flow measurement building on the flow measurement section. In non flood season, 8:00 and 20:00 respectively are observed once a day. If there is rainfall, observe twice at 8:00 and 20:00 respectively when the daily water level changes slowly; observe four times at 2:00, 8:00, 14:00 and 20:00 respectively when the daily water level changes greatly or there are slow peaks and valleys. During the flood season, when the water level changes violently, it shall be observed in multiple of 6 minutes. 2. Flow measurement method of runoff station in the test site: Basel measuring flume is used for flow measurement, and push flow formula is used for flow calculation. 3. Sediment sampling and treatment: the sediment in the flow measurement section is sampled by the thalweg buoy method, and the number of sediment sampling depends on the number of changes in the flood water level. In order to control the change of sediment concentration, the number of sampling is increased during the flood peak. The sample was treated by displacement method.

Data quality description

Manual observation shall be conducted by professional technicians; during data entry, four levels of manual verification shall be conducted, including tabulation, primary calibration, re calibration and audit, so as to ensure data quality.
