Description

Technical Field

[0001] The utility model relates to the technical field of water body sampling, in particular to a surface runoff sampling device. Background Art

[0002] After atmospheric precipitation falls to the ground, part of it evaporates and turns into water vapor and returns to the atmosphere, part of it infiltrates into the soil and becomes groundwater, and the rest of the water flows along the slope, through gullies and streams, into rivers, and into the ocean. This kind of water flow is called surface runoff. Surface runoff sampling is a necessary step in monitoring surface runoff water bodies.
