Pore pressure measurements 



Sequence of events. Pore pressure measurements were acquired 

 simultaneously with wave profile and wave velocity measurements. The 

 MTS-VAX data acquisition system, described in Chapter 13, was used for all 

 three measurements. Each separate data run was initiated with the control 

 signal to the wave generator. Length of run was predetermined and sampling 

 was terminated approximately 1 min after the wave generator was shut down. 

 The reader is referred to Chapter 1 for an expanded discussion of specific 

 wave conditions.
