In the sediment of the estuary of the Chikugo River where inflow load quantity to Ariake Sea was bigger ,the carbohydrate was measured. The carbohydrate in the sediment surface of the estuary of the Chikugo River quantity was around 10 times higher than Ariake Sea sediment. Carbohydrate quantity to the time of edd tide is increased and to the times of a high-tide was decrease, it based on dissolubility carbohydrate caused by an adhesion alga. The dissolubility carbohydrates have chesion effect, and stabilization of sediment increased.
