    A good example of the sediment budget and longshore drift working together in the coastal system is inlet ebb-tidal shoals, which store sand that has been transported by long shore transport. [ 16 ] [ 17 ] As well as storing sand these systems may also transfer or by pass sand into other beach systems, therefore inlet ebb-tidal shoal systems ...

[1] The results of this process may be expressed in a quantitative or qualitative fashion.

    Once a site is suspected of being contaminated there is a need to assess the contamination. Often the assessment begins with preparation of a Phase I Environmental Site Assessment. [8] The historical use of the site and the materials used and produced on site will guide the assessment strategy and type of sampling and chemical analysis to be ...
