| Research Abstract |
This research confirmed the effect of groundwater and seawater interaction on nitrogen dynamics in coastal sediment of Seto-Inland Sea, Japan. Especially, this verified the process and volume of 1) groundwater- seawater interaction, 2) nitrogen discharge by groundwater, 3) attenuation and generation of nitrogen in various tidal slopes, 4) the balance of denitrification and nitrogen fixation in bay scale, 5) groundwater and nitrogen discharges to the sea in Osaka bay and Bisan seto.
