Project objectives
1. To conduct a scoping study to assemble and
assess current understanding of barrier beach design, and;
2. To define the need for further research
In particular, the research will review current
understanding of:
- threshold conditions for over-washing;
- causes of breaching;
- through-flow;
- prediction of the profile development of the
beach following the onset of over-washing
- processes that may result in the natural rebuilding
of the crest;
- quantification of overtopping rates;
- quantifiable modification of the crest and
back barrier by overtopping and over-washing; and
- field performance of a range of key sites.
In addition, the project is expected to:
- gather information on and report current management
methods;
- estimate costs of current barrier beach management
practice; and
- understand and report constraints on management.
