The data set includes the flow measurement section map of runoff station, the result table of measured flow, the extract table of flood hydrological elements, the result table of successive flood tests, the daily average flow table, the daily average sediment concentration table and the daily average sediment transport rate table. See the basic situation of runoff station in wangmaogou watershed for the situation of runoff station.\n

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.\n2. Flow measurement method of wangmaozhuang runoff station: adopt the calibrated natural section observation and the calibrated push flow formula for flow calculation.\n3. Sediment sampling and treatment: the sediment in the flow measurement section is sampled by the thalweg buoy method, and the number of sediment sampling depends on the number of changes in the flood water level. In order to control the change of sediment concentration, the number of sampling is increased during the flood peak. The sample was treated by displacement method.
