Rotational effects on the seiching mode were checked by specify- 

 ing the Coriolis parameter as 0.75 a , 1.00 a Q , and 1.25 o Q where a Q 

 is the angular - frequency of the fundamental mode. The computed fre- 

 quencies, a , were compared with those obtained by Rao (1966) and 

 Platzman (1972). 



Table G-l gives the comparison with Rao's and Platzman' s results.

Although the errors occurring with f/a Q > 1.00 are large, these 

 values of f/cr represent stern tests of the algorithm. It is 

 definitely encouraging that no evidence of instability is indicated 

 in the simulated hydrographs.
