Research data for rill erosion caused by inflow

The data were collected from 27 inflow tests under the conditions of 3 slopes (5°, 15°, and 25°) and 3 inflow rates (4, 6, and 8 L/min), including the rill morphological changes, the parameters of rill flow mechanics and hydrodynamics, the sediment content of rill flow, soil loss, and other relevant information.
