Climax 



Final and most stable of series of communities in succession, remaining 

 relatively unchanged as long as climatic and physiographic factors remain 

 constant. 



Cobble 



Naturally rounded reck, 3 to 10 i n diameter. 



Cofferdam 



A temporary watertight structure built in the water and pumped dry for 

 construction of piers, bridges, dams, etc. 



Community 



Association of plants and/or animals in given area or region in which 

 various species are more or less dependent upon each other. 



Coquina 



A soft porous limestone with high shell and coral content. 



Cove 



Small, sheltered recess in coast, often inside larger embayment. 



Cumulative effects 



Effects which result from an accumulation of a number of structures in 

 a coastal area. 



Current , long shore 



Littoral current in the breaker zone moving parallel to the shore. 



De adman 



A wooden pile, concrete Mock or horizontal timber placed landward of a 

 bulkhead and used to anchor the structure; (see Figure 27). 



Delta 



Alluvial deposit, triangular or digitate, formed at river mouth. 



Design wave height 



Wave which is used for designing coastal structures such as revetments, 

 breakwaters, jetties, or groins. The wave height and period assists the 

 designer in selecting sizes of armor units and other features of the 

 structure. The design wave will probably not be the maximum wave for 

 economic reasons. 



Detached breakwaters 



Breakwaters standing free of the shore; see breakwater . 



Dike 



Wall or mound built around low-lying area to control flooding. 



Disclimax 



Plant community in which species composition is maintained by continuing 



disturbance.
