IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Research on improvement of bottom sediment environment by porous material

The environmental condition of the coastal marine area of Japan is characterized with regular red tide and oxygen depleted water occurrence in the sea bottom of the Seto Inland Sea in summer season. Our concerns are about the impact of those phenomena on the biological production process in the sea area. We have noticed some kinds of metals in the semi-enclosed bays like Yashima Bay, located in the eastern part of the Seto Inland Sea, as well as serious deterioration in the water quality and bottom sediment. Therefore, we proposed in this paper a technology for improving the marine sediment environment by setting a new porous material, which consists of slag as one of the industrial by-products. The porous material has appropriate void and strength to efficiently habituate the marine organisms. We also examined the effect of the sediment quality improvement by using that porous material. The developed porous material can remove the metal from contaminated bottom sediment.
