TY - Data T1 - Runoff and sediment observation data set of Nanxiaohegou watershed in Loess Plateau Gully Region from 2011 to 2018 A1 - Yellow River Water Conservancy Commission Xifeng Soil and Water Conservation Scientific Experimental Station DO - 10.12072/ncdc.HWXFZhan.db0048.2020 PY - 2020 DA - 2020-11-18 PB - National Cryosphere Desert Data Center AB - <p>This data set is the runoff and sediment observation data of four runoff stations in the Nanxiaohegou watershed in the Loess Plateau Gully Region from 2011 to 2018. Nanxiaohegou watershed is located in the edge of Dongzhiyuan in Xifeng District, Qingyang City, Gansu Province. It is a tributary of the Jinghe River on the left bank of Puhe River. Its geographical location is 107 ° 30 ′ 03 ″ ~ 107 ° 37 ′ 26 ″ e, 35 ° 40 ′ 51 ″ ~ 35 ° 44 ′ 55 ″ n. from 2011 to 2014, the basin area was 36.3 km 2, and the updated basin area was 38.93 km2 after 2015. The altitude is 1050 ~ 1423m.Shibamutai runoff station is the control station of Nanxiaohegou River Basin. It is located under the slope angle of the back water of the earth dam. The catchment area above the observation section is 32.78km2. In the initial stage, the main purpose of observation is to observe the changes of runoff and sediment in the basin after different degrees of treatment. Due to the retention of part of the runoff by the upstream Huaguoshan reservoir, the runoff and sediment data observed by the 18 Mu station are only used as Comparative analysis of benefits after reservoir impoundment. The experimental observation sections are Bacher weir and rectangular thin-walled weir.The outflow station of Huaguoshan reservoir is the control station at the outlet of Huaguoshan reservoir in the basin, with a catchment area of 26.70km2. It mainly observes the regulation and storage effect of the reservoir and the law of sediment deposition. Rectangular weir and weir are used to observe water.Yangjiagou runoff station is the runoff station of harnessing ditch in the basin. The observation section is located in the main channel of Yangjiagou where biological measures are mainly used for soil and water conservation control. The catchment area above the observation section is 1.01km2. It mainly observes the treatment benefits of biological measures and the treatment measures and methods of branch ditches.
