This dataset includes runoff and sediment observation data from three runoff stations in the Qiaogou Basin in 2022. Through water level observation at the runoff station's flow measurement section, sediment sampling, and calculation of runoff and sediment yield during runoff production. The data includes a distribution map of stations in the Qiaogou watershed, a cross-sectional map of runoff stations, an excerpt of flood hydrological elements, and a table of successive flood test results. The situation of runoff stations can be found in the "2022 Situation Description of Qiaogou Basin".

Artificial timing observation
1. The flow measurement method of Qiaogou runoff station: the triangular groove is used for flow measurement, and the flow calculation is based on the push flow formula.
2.The flow measurement method of Qiaogou No.1 Branch Ditch and Qiaogou No.2 Branch Ditch runoff station: the triangular groove is used for flow measurement, and the flow calculation is based on the push flow formula.
3.Sediment sampling and treatment: the midstream buoy method is used to sample the sediment at the flow measurement section. The frequency of sediment sampling depends on the frequency of flood water level change, and the sampling frequency is increased to control the change of sediment concentration at flood peak. The sample was treated by displacement method.
In the process of observation, when there is an abnormal value of the self recording rain gauge, the observation value of the ordinary rain gauge is used for interpolation and verification; in the process of data entry, there are four levels of manual verification, which are tabulation, primary calibration, recalibration and audit, to ensure the data quality.
