Abstract
With past development in littoral region through land reclamation and port improvement etc., a lot of natural tideland have been disappeared, opportunity to have contact with the natural sea has been decreased and habitat, egg-laying site and growing land for a huge variety of life have also been decreased. Because of these points, recovery of mudflats and see grass bed is gathering momentum, but there are the depletion of natural materials and the shortage of chemical knowledge on recovery of artificial tideland.
In this study, two years verification test applying granulated fly ash to materials of artificial tideland at the actual sea was conducted mainly to examine applicability of granulated fly ash to growing bed for clams.
