5. Where jetty systems and navigation cinannels are required, develop sedinnent 

 bypassing and recycling schennes into the design requirement. At Belle Pass and 

 Barataria Pass, a sediment bypassing scheme would alleviate downdrift erosion 

 problems. At the Houma Ship Channel, a sediment recycling scheme of the dredge 

 spoil could provide a source of sediment for nourishing the Isles Dernieres and the 

 Timbalier Islands. 



6. Conduct a sand resource inventory of the entire Louisiana continental shelf. 

 Location, quantity, and quality of potential sediment borrows must be known before 

 any beach nourishment projects can be designed. Conducting small site-specific 

 sand resource inventories is not cost effective.

Scientific results presented in this paper were sponsored by the Louisiana Office of 

 Coastal Zone Management through a grant to the Laboratory for Wetland Soil and 

 Sediments in the Center for Wetland Resources at Louisiana State University, Drs. W.H. 

 Patrick, Jr., and l.A. Mendelssohn, Principal Investigators. Logistical support was 

 provided by the Sea Grant Auxilliary. This research was conducted when Shea Penland 

 was with the Laboratory of Wetland Soils and Sediments and Ron Boyd was with the 

 Louisiana Geological Survey. Mary Penland edited the manuscript.
