For example, a more refined sea-level record over millions of years is commercially interesting because it allows a better understanding of coastal sediment sequences that are relevant to the petroleum industry.
356 crore which will cover --mapping, delineation and demarcation of the hazard lines and delineation of the coastal sediment cells along the mainland coast of India; mapping, delineation and demarcation of environmentally-sensitive areas that require protection.
Appropriately held in New Orleans, the 6th International Symposium of Coastal Engineering and Science of Coastal Sediment Processes (May 2007) heard a keynote address from a representative of the Louisiana Department of Natural Resources regarding recent hurricane damage.
Transport of these particulate-bound contaminants within coastal areas usually coincides with sediment transport processes; thus there are numerous examples around the world where coastal sediment deposits reflect waste-disposal histories.
They cover shallow-water waves, water-level fluctuations, coastal structures, challenges to developing and designing offshore structures, ports and harbors, coastal sediment processes, the flow of water and nutrients in enclosed bays, sustainable coastal development, coastal hazards, physical modeling, and coastal engineering practice and education.

There is an abundant coastal sediment supply being delivered from the erosion of a drowned delta to the north as well as sediment arriving from the south, transported from the Delaware River (McMaster, 1954; Dobday, 1981).
If a long-term, net-offshore transport of coastal sediment occurs in the study area due to the wave climate characteristic of the Great Lakes (USAEDD 1975, 1976), then the isolation and protection of back-shore coastal sediments through the use of any shore protection technology will ultimately result in increasing loss of near-shore sand systemwide.
