SSHCZO -- Streamflow / Discharge, Groundwater Temperatures, Electrical Conductivity -- Shale Hills -- (2015-2018)

A 2.5 foot fiberglass H-flume with 7’ 6” 3D approach section, 10” diameter stilling well, and dual scale staff gauge is located at the outlet of the stream Shale Hills Susquehanna Critical Zone Observatory Stream (40.664848, -77.907245, elevation 259.08 m) is used to monitor stream discharge accurately during high and low flows. Water depths are measured using a Decagon CTD-10 sensor recording in one-minute intervals, integrated to 10 minute values and converted to discharge using a rating curve developed by Open Channel Flow for the specific flume dimensions. An offset of 54 mm has been entered in the Campbell Science CR1000 data-logger program to account for the difference between the pressure sensor spacing and distance from bottom of stilling well to flume.

位于Shale Hills Susquehanna关键地带观测站溪流（经纬度：40.664848, -77.907245，海拔259.08米）出口处的2.5英尺长的玻璃纤维H型流道，配备7英尺6英寸的3D进流段、直径10英寸的静压井和双尺度杆式测流仪，用于精确监测溪流在高流量和低流量期间的流量。水深采用Decagon CTD-10传感器进行测量，以一分钟为间隔记录数据，并将数据整合为每十分钟的平均值，随后利用由Open Channel Flow针对特定流道尺寸开发的标定曲线将其转换为流量值。在Campbell Science CR1000数据记录仪程序中已输入54毫米的偏差值，以补偿压力传感器间距与静压井底部至流道之间的距离差异。
