本数据集为2022年王茂沟流域径流站径流、泥沙观测数据，通过径流站测流断面水位观测，泥沙取样，计算产流时的径流、泥沙量。数据包括王茂沟径流站测流断面图、洪水水文要素摘录表、逐次洪水测验成果表、逐日平均流量表、逐日平均含沙量表、逐日平均输沙率表。径流站情况见《王茂沟流域2022年情况说明》。\n

Through the observation of water level at the runoff station measurement section, sediment sampling, and calculation of runoff and sediment yield during runoff production. The data includes the flow measurement cross-section map of Wangmaogou runoff station, excerpts of flood hydrological elements, results of successive flood tests, daily average flow rate, daily average sediment concentration, and daily average sediment transport rate. The situation of runoff stations can be found in the \"2022 Situation Description of Wangmaogou Basin\".\n

The water level observation method of runoff station is: wangmaogou runoff station uses the water gauge on the side wall of the building to measure the water level. In the non flood season, the water level is observed once a day at 8:00 and 20:00 in case of rainfall; the observation is conducted four times at 2:00, 8:00, 14:00 and 20:00 when the daily water level changes greatly or has a slow peak and valley. When the water level changes violently in flood season, the observation shall be made in multiples of 6 minutes.\n2.The flow measurement method of wangmaozhuang runoff station: the calibrated natural section observation by manual arrangement is adopted, and the calibrated flow formula is used for flow calculation.\n3.Sediment sampling and treatment: the midstream buoy method is used to sample the sediment at the flow measurement section. The frequency of sediment sampling depends on the frequency of flood water level change, and the sampling frequency is increased to control the change of sediment concentration at flood peak. The sample was treated by displacement method.\n",
