No attempt was made to select only observations for the Kuwait 

 Harbor area. 



Waves 



In general waves in the Kuwait area are low since fetch distances 

 are short except in the approaches. The usual low seas are interrupted 

 most frequently during the winter months by rough seas lasting from 

 a few hours to several days; these are induced by the gusty "shamal" 

 type winds accompanying frontal passages. In the harbor approach 

 areas off Fahihil long swell from the south is observed about 1/4 

 of the time during the winter and early spring, and rarely during other 

 seasons. Table VII is taken from the most recent revision of H. O. 

 Sailing Directions for the Persian Gulf (8) and contains seasonal 

 percent frequencies of sea and swell for Kuwait Harbor and adjacent 

 waters. 



During this particular survey there was little opportunity to use 

 a wave meter or wave pole. However, sea and swell entries were 

 recorded regularly on the ship logs throughout the survey period. 

 To supplement these, a series of special wave observations was made 

 during several "shamal" periods. These wave data are contained in 

 Table VIII. 



Color and Transparency 



Observations of color and transparency were extremely few and 

 insufficient to warrant separate tabulation. These data are quoted 

 directly from the observation logs in order to preserve the descriptive 

 details which might be of value. The first of these repeats in part 

 an observational note in Section IV of this report. 



"At the beginning of the flood tide (0930- 1000) on February 

 15, 1949, at the entrance to Kuwait Harbor, a long, rather 

 wide, tide eddy was noticed. It was found that on a calm 

 day these eddies stir up separate clouds of mud from the 

 bottom that give the surface of the water a brown, mottled 

 appearance. The eddy line moves up into the harbor and 

 dies out in the vicinity of Ras al Ajuzah as the flood becomes 

 more pronounced. The countercurrent between Ras al 

 Ajuzah and Ras al Ardh -- as proved by Current Station 

 No. 10 -- flows back out into the entrance channel south 

 of the eddy line. 



"Another distinct line was observed at 1015 the same day
