This data set is the runoff and sediment observation data of four runoff stations in peijiamaogou watershed from 1960 to 1979. The runoff and sediment amount during runoff generation are calculated by water level observation and sediment sampling of runoff station. The data set includes the measured large section map of runoff station, the measured discharge result table, the extraction table of flood hydrological elements, the result table of successive flood measurement, the daily average discharge table, the daily average sediment concentration table and the daily average sediment transport rate table. See the basic information table of runoff stations in peijiamaogou basin for the situation of runoff stations.

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.
