Author:Hiroyuki YAMANISHI, Keisuke KUROGI and Tomoaki SAKATATitle:Effect of sediment accumulation and benthos habitat potential by the SodagaramiAnnouncement information: Vol: 25 Page: 347-352Keyword:Ariake sea, tidal flat, suspended matter, mud transport, benthos, simulationAn abstract:Recently, inflow of abnormal red tides and anoxic waters in the tidal flat has been observed in summer, and the change of mud flat environment is on-going problem in the Ariake sea. This gives the greatest impact for the living animals in an inter tidal area. In this study, suspended matters transport around the Sodagarami structure in the mud flat of the Ariake sea were measured for a long term. The survey site is the Nanaura mud flats near Kashima city in Saga, Japan. The hydrodynamic characteristics and prediction of suspended sediment transport was studied using a numerical model. As a result, it was revealed that the Sodagarami method is useful to make the sedimentation of fine particles accelerate. Also, the potential of benthos habitat using the Sodagarami method were estimated by the composite suitability index.An abstract:Recently, inflow of abnormal red tides and anoxic waters in the tidal flat has been observed in summer, and the change of mud flat environment is on-going problem in the Ariake sea.
