本数据集为1954-1958年黄土丘陵沟壑区第三副区大柳树沟流域沟口径流站观测观测数据。包括泥沙观测和降水观测数据。降水观测使用的雨量器有自记雨量计和普通雨量器两种。自记雨量计型号有两种：一是仿苏П-1型自记计；二是天津海洋仪器厂制造的DSJ2型虹吸自记计。普通雨量器按承雨口径大小分两种，即口径20cm的标准雨量筒及口径11.3cm的简易雨量筒。普通雨量筒筒口距地面高度为2m，降水量一般按两段值观测。各站除按规定时段观测外，还要记载降水起讫时间。\n大柳树沟测流建筑物为三角形宽顶堰，用率定并经实测点修正的水位～流量关系根据水位推流数据。\n含沙量观测采用水边一点法取样。取样次数与测流次数基本相同，有时为控制含沙量变化而适当增加取样次数。沙样处理一般采用过滤法。\n包括逐日降水量观测成果表、降水量摘录表、各时段最大降水量表（1）、径流站洪水水文要素摘录表、径流站逐次洪水测验成果表。

Including sediment observation and precipitation observation data. There are two kinds of rain gauge used in precipitation observation, self recording rain gauge and ordinary rain gauge. There are two types of self recording rain gauge: one is imitated Su Ν - 1 self recording meter; the other is dsj2 siphon self recording meter made by Tianjin Ocean instrument factory. The ordinary rain gauge is divided into two types according to the size of the rain bearing caliber, i.e. the standard rain tube with the diameter of 20 cm and the simple rain tube with the diameter of 11.3 cm. According to the general rainfall, the distance between two pipes is 2m. In addition to observing according to the specified time interval, each station should also record the beginning and ending time of precipitation.\nThe flow measuring structure of daliushugou is a triangular wide crested weir. The water level discharge relationship calibrated and corrected by the measured points is used to deduce the flow data according to the water level.\nThe sediment concentration was measured by one point method at the water edge. The number of sampling is basically the same as that of current measurement. Sometimes, the sampling frequency is increased appropriately to control the change of sediment concentration. The filtration method is usually used for sand sample treatment.\nIt includes daily precipitation observation results table, precipitation extraction table, maximum precipitation table of each period (1), hydrological elements extraction table of runoff station, and successive flood test results table of runoff station.

The standard of flood peak discharge is greater than 1 m 3 / s, and the one greater than this value is extracted.\nIn the process of compilation and input of observation data, there are four levels of manual verification, including tabulation, primary calibration, recheck and audit, so as to ensure the data quality.
