  • Remediation of Coastal Marine Sediment using Iron

    Ahmad Seiar Y.Y. Nakamura, T. Miyatuji, Y. Hagino, T. Kobayashi, Y. Shigeoka and T. Inoue

    Proceedings of the 5th International Conference on Geographical Information Systems Theory, Applications and Management (GISTAM 2019) ( SCITEPRESS – Science and Technology Publications, Lda )    335 - 339   2019.05  [Refereed]

    Joint Work

     View Summary

    Laboratory experiments were conducted to evaluate the effectiveness of iron application to surface sediment on the suppression of hydrogen sulfide release from sediments. By using sediments cores collected from Mikawa Bay, Japan at every month from June to September 2017, incubation experiments were made for three weeks under anoxic conditions with or without application of the iron containing compounds; the iron oxide or iron hydroxide. The results revealed that both uses of the iron oxide and iron hydroxide significantly reduced sulfide release flux from the sediment into the overlying water. Iron hydroxide was more effective than iron oxide in the suppression of sulfide release, as concluded from 21-day of incubation. While, no significant difference was observed among the control group after 21day incubation. Therefore, it can be conclude that the application of iron to the sediment is a promising method to remediate contaminated sediments in eutrophic water body.

    Journal of Japan Society of Civil Engineers, Ser. B2 (Coastal Engineering) ( Japan Society of Civil Engineers )  74 ( 2 )   I_1201 - I_1206   2018

    Joint Work

     View Summary

     The mortality of coral bleaching would have been reduced by regular higher turbidity in Kabira Bay which was inner bay of Ishigaki Island. From the spectrum analysis and the flow simulation analysis, the origin of high turbidity water mass was estimated to be the western tidal flat area of the inner part. Meteorological and oceanic conditions with increased turbidity were identified by continuous observation and the mechanism of the increase in turbidity was examined by investigation of water quality, bottom sediment, flow condition. The strong south wind caused advection and upwelling of turbidity, but the frequency was low. High waves cause Wave Set-up, but the influence on turbidity in shallow layer was small.
