3 ABSTRACT 



A study was conducted to determine the relative merits of various flowmeters 

 and techniques used in shallow-water oceanography. Although problems still exist 

 with the use of electromagnetic flowmeters, it was concluded that these represent 

 the best medium for measuring steady-state currents at depths where the magnitude 

 of orbital velocities caused by surface waves can be several times larger than 

 steady-state flows.
