SSHCZO -- Groundwater Temperatures, Stream Water Temperatures -- Shale Hills -- (2015-2016)

Streambed water temperature was monitored at 6 streambed piezometers at the Shale Hills Critical Zone Observatory since May 2015 at a 15-min interval. These are RAW data to estimate the groundwater seepage rates. Each piezometer has two thermal probes at about vertically 15-20cm apart. The daily seepage rate is inferred from the amplitude and phases differences between the two streambed temperature measurements (Hatch et al., 2006). The daily seepage rate at each streambed piezometer point is inferred from the amplitude and phase differences between a pair of water temperature measurements. The detailed method is available in Hatch et al. (2006). Matlab codes for the seepage rate computation are available (contact Tess Russo at [e-mail]).
