Three temperature probes
were installed to record temperature
profiles (right) at locations of resistivity
anomalies (locations shown below).
The Matlab program
VFLUX was used to process the data and
calculate the downward flux at each of these
locations, with zones of high resistivity
corresponding to high values downward flux
and zones of high resistivity corresponding
to moderate values of downward flux or
upward flux of water through the streambed.
