[AHW26-02] Cl- concentration in pore water beneath Tokyo bay area, Urayasu, Chiba Japan

*Takeshi YOSHIDA1, Osamu KAZAOKA1 (1.Research Institute of Enviornmental Geology, Chiba)

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.
