longshore transport will pass seaward of the structure and effects on the 

 neighboring shoreline will be less drastic. However, structural integrity may 

 become a problem due to scour at the structure toe. Figure 21 shows a seg- 

 mented low-crested, permeable breakwater that was placed inside the breaker 

 zone. Substantial accretion occurred but there is still access to the water. 

 The structure was built at a shallow depth, permitting more economical 

 construction.
