PART IV: CONCLUSIONS 



62. The Carolina project performed generally as expected but experi- 

 enced slightly higher volume losses than originally anticipated. Until the 

 material in the construction berm along the southern 10,000 ft of the project 

 moves to the lower portion of the active profile, volume losses along this 

 segment will probably continue to be high. Eventually, the southern 10,000-ft 

 segment is expected to attain some degree of stability. Along the northern 

 4,000 ft, the sediment deficit caused by Carolina Beach Inlet remains a prob- 

 lem and will require a continuous renourishment program with materials ob- 

 tained from the Carolina Beach Inlet sediment trap. 



63. The sediment trap in Carolina Beach Inlet functioned fairly well 

 but was located too close to the main flow through the inlet to be completely 

 effective. Relocation of the sediment trap seaward and away from the main 

 flow should greatly enhance its overall sand trapping ability. Dredging of 

 the channel through the ebb tide delta eliminated the opportunity to evaluate 

 the trap's effect on the delta and ebb tide channel.
