Through the water level observation and sediment sampling of the runoff station, the runoff and sediment amount during runoff generation are calculated. The data set includes the measured discharge results of peijiamao runoff station, Qiaogou runoff station, Qiaogou yizhigou runoff station and Qiaogou erzhigou runoff station, extract table of flood hydrological elements, successive flood test results, daily average discharge table, daily average sediment concentration table and daily average sediment transport rate table.

The method of observing the water level of the runoff station is: read the water gauge of the current measurement section of the current measurement section. It is observed once every day during the non-flood season. If there is rainfall, the daily water level changes slowly at 8 o'clock and 20 o'clock. Twice; Observe four times at 2 o'clock, 8 o'clock, 14 o'clock, and 20 o'clock when the daily water level changes greatly or there are slow peaks and valleys. Observe the multiples of 6 minutes when the water level changes drastically during the flood season.\n2. Flow measurement method of Peijiagou runoff station: the small-buoy method is used to measure the flow during the flat water period, and the Zhonghong buoy method is used when the flow is large during the flood period and soars sharply. 5 times, 2 ~ 5 Zhonghong buoys are dropped each time, and 2 ~ 3 effective buoys with the shortest history, normal operation and the closest flow velocity are selected from them, and the difference between their operating history should not exceed 10 ~ 15% as a guideline. At the same time, observation of different wind directions, wind power and other ancillary items in the current measurement.\n3. The flow measurement method of Qiaogou runoff station: Triangular groove flow measurement is adopted, and the flow calculation adopts the push flow formula.\n4. Qiaogou one ditch and Qiaogou two ditch runoff station flow measurement methods: Basel water trough flow measurement was used from 2001 to 2005, and triangle trough water flow measurement was used from 2006 to 2010. The flow calculation adopts the push flow formula.\n5. Sediment sampling and treatment: Zhonghong buoy method is used to sample the sediment on the cross-section of the river. The frequency of sediment sampling depends on the number of changes in the flood level. During the flood peak, the number of samplings is increased to control the change of the sediment content. Samples were processed using the displacement method.
