", "ds_process_way": "1.水位观测：裴家峁径流站利用设置的基本水尺进行水位测定。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：平水期流量小时用小浮标法施测，洪水期流量较大且暴涨暴落时用中泓浮标法，其每次较大洪水过程，一般测流不少于5次，每次投放2~5个中泓浮标，从中选用历时最短，运行正常、流速最为接近的2~3个为有效浮标，其运行历时相差不得超过10~15%为准则。 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。

Water level observation: peijiamao runoff station uses the basic water gauge to measure the water level. In non flood season, the observation shall be conducted once at 8:00 a.m. in case of rainfall, the observation shall be conducted twice at 8:00 and 20:00 when the daily water level changes slowly; when the daily water level changes greatly or there is a slow peak and valley, it shall be observed four times at 2:00, 8:00, 14:00 and 20:00. When the water level changes violently in flood season, the observation shall be made in multiples of 6 minutes. 2. Flow measurement method: small buoy method is used to measure the flow when the flow is small in the normal period, and the midstream buoy method is used when the flow is large and rises sharply and falls sharply in flood period. Generally, the current is measured for no less than 5 times in each large flood process, and 2-3 middle buoys with the shortest duration, normal operation and closest velocity are selected as effective buoys, and the difference of operation duration shall not exceed 10-15% 。 3. 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.
