The expansion of the Beach Erosion Board research facilities 

 by the construction of a large wave tank and a coast model test basin 

 is in progress adjacent to the Board's' offices and laboratory. A 

 brief description of these facilities appeared in the Bulletin, Vol. 

 3, No. 4, October 1, 1Q49. Contract work is about 60 percent complete 

 at the time this publication goes to press. 



Excavation work for the wave tank and coast model basin has been 

 completed and concrete work is now progressing slightly ahead of schedule, 

 Progress photographs of the construction operations on the wave tank are 

 shown in figures 1-5. Progress pictures of the basin construction will 

 be published in a later issue of this publication.
