Observe the secondary precipitation, runoff volume, and sediment content of runoff generated by different slope runoff fields in Yulin Gully, and compare the water and sediment reduction benefits of different slopes. The situation of the runoff field can be found in the description of the runoff field at different slopes in Yulin Gou in 2022. The data includes the results of successive runoff and sediment tests of different slope runoff fields in Yulin Gully, as well as the measured results of soil moisture content.

Rainfall observation: the observation instruments for precipitation include SM1 ordinary rain gauge with diameter of 20cm and dsj2 siphon self recording rain gauge.

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.\n3.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.",
