Dear Listers,
As a part of my PhD project, I am going to deploy a number of water level and temperature loggers (probably type HOBO U20) at different sites of a small river and its floodplain. The system is governed by strong summer and winter inundations, the low-water line is around 0.7 m, strong winter inundations can reach as high as 5 m. I am particularly concerned about loads of tree trunks and timber, which can damage, destroy or detach loggers (and quickly deplete my limited budget). I was wondering if anyone of you has experience with the securely deploying submersible data loggers in comparably dynamic riverine systems. I am considering an approach in which the logger is attached to an erected metal pole, which is rammed deeply into the river bed (e.g., 50 – 80 cm deep). The logger would be attached to the pole downstream (e.g., with cable, cable ties, or similar, and a back-up system, if possible). Do you think this approach is feasible, or did you successfully apply different set-ups? I highly appreciate your advice. Thanks a lot in advance. Best wishes, Claudia Claudia Pogoreutz, M.Sc.
