Characteristics of Groundwater Flow and Tidal Flat formed by River Structure in the Estuary

摘要: The variations of river flow by structure created ecological tidal flat in Ota River. formation mechanism was analyzed the distribution soil environment and variation water level quality groundwater. In River, groundwater kept high main channel because tide pool is formed revetment flood plane. occurred gradient ground between with variability. porosity level. It considered that which content low organic matter transportation flow.
