This dataset is the runoff field data of different measures for afforestation in the Xindian Gou watershed of the first sub area of the loess hilly and gully region in 2024. Observe the secondary precipitation, runoff volume, and sediment content of the runoff field generated by different measures in Yulin Gully, and compare the water and sediment reduction benefits of different measures. The data includes the results of successive runoff and sediment tests of different measures in Yulin Gully, as well as the measured results of soil moisture content. The situation of the runoff field can be found in the "2024 Situation Explanation of Different Measures in Yulin Gully"

Manual timing observation
1.Rainfall observation: There are SM1 ordinary rain gauge with diameter of 20cm and dsj2 siphon self recording rain gauge.
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 compilation and input of observation data, there are four levels of manual verification, including tabulation, primary calibration, recheck and audit, so as to ensure the data quality.
