1.水位观测：韭园沟径流站利用建筑物侧壁上的水尺进行水位测定，非汛期每日8时观测一次，如有降雨，日水位变化缓慢时8时、20时观测两次；日水位变化较大或出现缓慢的峰谷时按2时、8时、14时、20时观测四次。汛期水位变化剧烈时按6分钟的倍数观测。 2.测流方式：平水时采用三角槽测流；水位高于三角槽时，在矩形溢洪道采用浮标法测流，浮标系数采用黄委子洲径流试验站浮标试验结果。 3.泥沙取样及处理：测流断面泥沙采用中泓浮标法取样，取沙次数取决于洪水水位变化的次数，洪峰时为控制含沙量变化而增加取样次数。样品处理采用置换法。

This dataset includes runoff and sediment observation data from the Jiuyuangou watershed runoff station from 2021 to 2022. Through water level observation at the runoff station's measuring section, sediment sampling, and calculation of runoff and sediment yield during runoff production. The data includes the flow measurement cross-section map of the Jiuyuangou watershed, an excerpt table of flood hydrological elements, a table of successive flood test results, a table of daily average flow, a table of daily average sediment concentration, and a table of daily average sediment transport rate. The situation of the runoff station can be found in the \"Explanation of the Jiuyuangou Basin from 2021 to 2022\"

  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.\n

  1. Flow measurement method of channel diameter flow station: when the water level is higher than the triangular channel, the buoy method is used to measure the flow in the rectangular spillway, and the buoy coefficient is based on the buoy test results of huangweizizhou runoff test station.

  2. Flow measurement method of wangmaozhuang runoff station: adopt the calibrated natural section observation and the calibrated push flow formula for flow calculation.
    3. \n
  3. 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.
