<p>This data set is the runoff field data of different landform types in Qiaogou watershed, the first sub region of Loess Hilly and gully region from 2011 to 2020. The secondary precipitation, runoff and sediment yield of runoff from different geomorphic types in Qiaogou watershed were observed. The flow field is shown in the table of basic flow field of bridge ditch. </p>

<p>1. Rainfall observation: there are SM1 ordinary rain gauge with diameter of 20cm and dsj2 siphon self recording rain gauge. The data of Qiaogou No.5 rainfall station are used for the precipitation of runoff plots of different geomorphic types in Qiaogou.
2.Sediment sampling and treatment: different observation facilities are adopted for runoff and sediment, including triangular weir, triangular groove, water distribution tank and runoff pool. Sand ocean is collected by triangular weir and triangular groove in the process of runoff generation; the water level of runoff pool is read immediately after precipitation and runoff is terminated, and runoff is calculated according to the area and water level of water distribution tank and runoff pool The sediment sample (500cm3) was taken by mixing water evenly, and the replacement method was used for sample disposal.
3.Soil moisture content: in a representative fixed site, after removing the surface weeds, samples were taken at a depth of 30 cm and determined by drying (weighing) method.
In the process of integration and input of observation data, there are four levels of manual verification, which are tabulation, primary calibration, re calibration and audit, to ensure the data quality.
