As for the necessity of planning of an artificial tidal flat, it is argued in various opportunities, and many studies about construction technique and biological investigation have been done. Accumulation of a result of biological investigation may become an evidence to evaluate the tidal flat environment, but it is not easy to evaluate the environment in tidal flat from a observations of the habitat, because of a large change of tidal flat environment around the river mouth. In this study, a usage of biological findings are examined and the relation between the habitat segregation and variation of tideland materials characteristics.
