<p>This data set is the observation data of dongzhuanggou (non governance) in Nanxiaohegou watershed of Loess Plateau Gully Region from 2011 to 2018. Dongzhuanggou (non treatment ditch) is a small branch ditch in Nanxiaohegou watershed, with a drainage area of 1.15km2 from 2011 to 2014 and 1.12km2 after 2015. Dongzhuanggou remains in its original state. Dongzhuanggou runoff station is located in the original ecological environment, the main channel of dongzhuanggou is 420m away from the highway of dongzhuanggou gully. The catchment area above the observation section is 1.12km2. It is compared with Yangjiagou as an untreated gully. At the same time, it is a typical small watershed in Loess Plateau Gully Region to study its soil and water loss law. This data set mainly includes precipitation observation data of dongzhuanggou rainfall station and runoff and sediment observation data of dongzhuanggou runoff station</p>
<p>It is mainly used to observe the starting and ending time of precipitation and to count the precipitation. When the interval time of precipitation is more than 15min, it is used as two precipitation observation records before and after the interval time. When the interval time is less than 15min, it is used as one precipitation observation record. If a precipitation crosses 8:00 and 20:00, it should be measured at 8:00 and 20:00.
This table is compiled for all artificial or self recording rainfall observation stations that control the precipitation in the whole catchment area.
Discharge calculation: the discharge is calculated from the observed water level, q = 4.8h2.55 Q: Discharge, unit: m3 / S; H: water level, unit: M. (2) Calculation of sediment concentration: P = WS / V * 1000 calculation of sediment concentration, P: measured sediment concentration, unit: kg / M 3; V: water sample volume, unit: cm 3; WS: dry sediment weight in water sample, unit: G.
<p>In the process of data integration and input, there are four levels of manual verification, namely tabulation, preliminary calibration, re calibration and audit, to ensure the data quality. </p>
