本数据集为1960-1979年裴家峁沟流域4个径流站径流、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。数据集包括径流站的实测大断面图、实测流量成果表、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。径流站情况见裴家峁沟流域径流站基本情况表。

", "ds_process_way": "1.径流站水位观测方法为：读取测流断面测流建筑物的水尺数，非汛期每日8是观测一次，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。\n2.裴家峁径流站的测流方式：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，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，从中选用历史最短、运行正常、流速最为接近的2~3个位有效浮标，其运行历史相差不得超过10~15%为准则。同时在测流当中观测不同风向、风力等附属项目。\n3.桥沟径流站的测流方式：采用三角槽测流，流量计算采用推流公式。\n4.桥沟一支沟、桥沟二支沟径流站的测流方式：2005年之前采用巴塞尔量水槽测流，2006~2010年采用三角槽测流，流量计算采用推流公式。\n5.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。
