LIVING HABITAT AND ENVIRONMENTAL VARIATION IN THE ESTUARY AFTER FLOODING

Abstract

As for the necessity of evaluating of tidal flat environment against floods, the Before-After-Control-Impact-Pared-Series for flooding is desired. Accumulation of a result of biological and physical investigations may become an evidence to evaluate the flooding, but it is not easy to on the living organisms variation for the flooding. In this study, a usage of biological findings is examined and the relation between the peripheral environment and variation of living organisms are studied. From this study it is found that despite a large change of tidal flat environment, the living habitat does not suffer crushing damage.
