Technologies for assessing the geologic and geomorphic history of coasts

The geologic and geomorphic history of coastal areas can be assessed using a four-part process: Thorough examination of technical literature and existing data from various archives. Field data collection and observation. Laboratory examination of samples collected in the field. Office interpretation of all project data, both newly collected and historic. It is vital that existing sources of data be evaluated before field studies are undertaken to prevent duplicating efforts and to guide the optimum sampling scheme. Field studies must be designed to answer basic questions about the study area: What physical processes affect the region? Does the underlying geology have a major influence? How has man modified or damaged the local environment? How much data can we afford to collect? Do we have the knowledge, ability, managerial skill, or money to properly analyze the data we want to collect at the project site? Is it more important to conduct a long-term sampling program or a shorter, more intensive program? Coastal scientists must be aware of how historic data were collected, and what assumptions and procedures were used by the original field technicians and analysts. The quality of historic data may vary from excellent to worse than useless. The use of instruments in the coastal zone is far from straightforward; incorrect use of instruments may lead to erroneous results because the wrong parameters may be monitored. Coastal engineers are urged to consult specialists in the field to help plan and conduct field studies. The analysis of contemporary coastal data is difficult and also requires the skills of specialists with experience in the particular types of instruments and methods that have been used.
