Tidal flat, classified as wetland of coastal zone, is critical transitional zone connecting sea with land,
and fulfills a variety of functions necessary for maintaining coastal ecosystem. Although it is critical to protect and
strengthen its functions of coastal wetlands, tidal flat has been mainly viewed as areas for development in Korea.
Therefore, this study provides with the effective mitigation measures so as to minimize adverse impacts of tidal flat
reclamation projects on the proper environmental values. So far, coastal development has not considered as important
the fact that development site consists of tidal flat in site selection. Therefore, large scale of tidal flats was abused.
Problems were emerged only after tidal flat development was already planned. The original plan had to be revised.
To rectify the problem, impacts of development on the environment need to be discussed based on the initial
development planning. Particularly, sandy beaches, rocky shores and shallow areas, underwater forest including
seagrass beds as well as the tidal flat in good condition should be excluded from development site.
