This data set is the runoff and sediment observation data from 1982 to 1990 at the gully diameter flow station in the third sub region of the Loess Hilly and gully region. The observation section of lueergou is a natural trapezoidal section; the flow velocity is measured by buoy method and the discharge is calculated by velocity area method; sediment sampling and flow measurement are carried out simultaneously, and the sampling times are the same as those of flow measurement, and the sediment concentration is measured by displacement method. This data set includes the measured discharge result table, flood hydrological elements extraction table, successive flood test result table, daily average discharge table, daily average sediment concentration table and daily average suspended sediment transport rate table.

Soil and water conservation data were compiled according to the "soil and water conservation test specification" (sl419) and "soil and water conservation technical specification" (sl419). Observation data shall be measured, calculated, sorted and analyzed in accordance with the requirements of "four follow-up". Errors and unreasonable records of observation shall be handled and corrected in time, and remarks shall be made. In the process of data compilation and input, four levels of manual verification, such as tabulation, primary calibration, re calibration and review, are carried out in strict accordance with relevant observation and compilation specifications and in accordance with the process of first proofreading, second proofreading, review and review, so as to ensure the quality of data results.
