Keywords:Alluvium, Profile of Cl- concentration, basal topography

We investigated Chloride concentration of Holocene and latest Pleistocene in Urayasu city, Chiba Japan. As a result of analysis, Chloride concentration of Holocene in this area is affected by flushing of rain and groudwater flow from Pleistocene.
