Abstract:

A multi-sensor piezometer is disclosed that includes a shaft and an upper chamber. The shaft houses a plurality of porous stones that operatively cooperate with the positive input of respective differential pressure transducers. The multi-sensor piezometer further includes a hydraulic dampening system which eliminates the effect of high frequency surface waves on the precision of the multi-sensor piezometer to measure pore pressures in marine sediments.
