20. ABSTRACT (Cdnttaua aa rararwm atA tf nacaaamcr ami fdeatitr by block number) 



Reversing currents in inlets on the Great Lakes are generated primarily by 

 long wave seiching modes of the lakes rather than by the astronomical tide. 

 Field measurements were conducted in 1974-75 at nine harbors on the Great 

 Lakes to: (a) Investigate the nature of long wave excitation and the gener- 

 ating mechanism for significant inlet velocities, (b) establish techniques for 

 predicting inlet-bay system response, and (c) develop base data for future 

 planning and design studies. Data collected include continuous harbor water
