This dataset is the runoff and sediment observation data of the Qiaozigou watershed in the third sub area of the Loess Hilly and Gully Region from 2021 to 2024. The Qiaozigou watershed is a small watershed for parallel observation and testing of governance and non governance. The Qiaozigong watershed is a governance watershed, and the Qiaozigxi watershed is a non governance watershed. The flow observation adopts the buoy method to measure the flow velocity, and the flow velocity area method to calculate the flow rate; Sediment sampling and flow measurement are carried out simultaneously, with the same number of sampling and flow measurement times. Sand samples are taken using the water edge one point method, and sediment concentration is measured using the displacement method.\n
This dataset includes a table of measured flow results, a daily average flow rate table, a daily average sediment concentration table, and a daily average suspended sediment transport rate table.

Generally, it is observed twice at 8:00 and 20:00 every day. The number of measurements in flood season depends on the increase of water conditions. It is required to be able to measure each flood peak, valley and complete flood process.\nSediment concentration observation: take sand samples by the one-point method at the water edge, and the sampling times are the same as the flow measurement times.
