V . SUMMARY 



Some of the ways in which a horizontal current influences surface gravity 

 waves and their measurement have been presented. Relatively simple hand- 

 calculation methods have been described which provide a means to estimate 

 (a) the wavelength modification due to a current, (b) whether a current can 

 prevent waves from reaching a particular location, (c) the correction needed 

 to compensate for a current when observed bottom pressure fluctuations are 

 used to estimate surface gravity wave heights, and (d) the range of periods 

 (if any) where the effects of currents can be neglected when surface wave 

 heights are estimated from bottom pressure fluctuations.
