Abstract

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 (40.6648488, -77.9072458, 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. Data are measured using a Decagon CTD-10 pressure transducer consisting of depth, water temperature and electrical conductance. The pressure sensor is located 15mm from the head (bottom) of sensor. The 15mm offset is accounted for in the CRBasic program providing actual values of water depth in the data table. Discharge values are derived from formulas in the Openchannelflow 2.5-ft H-Flume discharge table, and will report values of -9999 when depth is less than 6.1 mm where excessive error due to fluid flow properties and boundary conditions apply.
Date Range Comments: Data are quasi-live 10-minute interval depth and derived discharge values. End date is not fixed.
