This dataset includes runoff and sediment observation data from the Peijiamaogou watershed runoff station in 2022. The Peijiamaogou watershed is located in Suide County, Yulin City, Shaanxi Province, and is a first-class tributary of the Wuding River. By observing the water level of the flow measuring section at the runoff station, sampling sediment, and calculating the runoff and sediment volume during runoff production. The data includes the measured cross-section map of Peijiamaogou runoff station, the measured flow results table, the excerpt table of flood hydrological elements, the results table of successive flood tests, the daily average flow table, the daily average sediment concentration table, and the daily average sediment transport rate table. The situation of the runoff station can be found in the "2022 Situation Description of the Peijiamaogou Basin"

Manual timing observation
1. The water level observation method of runoff station is: read the water gauge number of the flow measurement building on the flow measurement section. In non flood season, 8:00 and 20:00 respectively are observed once a day. If there is rainfall, observe twice at 8:00 and 20:00 respectively when the daily water level changes slowly; observe four times at 2:00, 8:00, 14:00 and 20:00 respectively when the daily water level changes greatly or there are slow peaks and valleys. During the flood season, when the water level changes violently, it shall be observed in multiple of 6 minutes.
Manual observation shall be conducted by professional technicians; during data entry, four levels of manual verification shall be conducted, including tabulation, primary calibration, re calibration and audit, so as to ensure data quality.
