Beach Restoration and Nourishment
. Beaches that are eroding due
an interrupted or inadequate sand source can be stabilized by deposition of sand
brought from a source on land or of dredged materials.
SITE SPECIFIC DESIGN CONDITIONS. When developing a harbor or
other coastal project, much of the information that is required is site specific. This
requires the engineer to pursue various methods of field testing or existing data
regarding a site. The various types of information that are typically required are
foundation/geotechnical requirements, seasonal profile variation, flanking possibility,
seismic activity, ice, environmental considerations, construction considerations and
other design considerations (including regulatory, maintenance, etc.). CEM Section VI-
3 presents an overview of these subjects.
RELIABILITY OF DESIGN
. CEM Section VI-6 discusses reliability
design in depth. First, the engineer must decide on what design life is desired and/or
permitted by the budget. The level of protection must then be considered.
The CEM also provides information on the factors to be considered in a
complete design, necessary baseline data (field surveys, etc.) and concept of
risk/reliability in project design. Finally, the CEM discusses overall performance criteria.
