A low-cost multichannel recording piezometer system for wetland research

Harold F. Hemond
5 pp.

A low-cost system for the continuous recording of piezometric head is described. The system uses inexpensive earphones as sonar transducers, while using the narrow stem of the piezometer as an acoustic waveguide. The system overcomes several of the problems commonly encountered in tidal wetland investigations by providing rapid response, freedom from operator disturbance from peat compression and essentially continuous automatic data recording in a directly machine-readable medium.
