Investigation of the Density Advantage of the Iron Slag in Stabilizing Hydraulic Channel Bedforms

抄録

This study investigated the mobility characteristics of iron slag, as a heavier density granular material compared to natural sand, under currents and waves. Investigation was conducted by running a series of laboratory experiments. The experiment was targeted to reveal the iron slag critical shear stresses (τ_c) under currents and waves and the advantage of the iron slag to resist wave forces. Bed deformation and local scouring depths were among the main observed parameters. All the parameters were compared to the natural sand. Experiments were mostly conducted in a wave flume that generated regular waves with some variations of wave heights (H) and wave periods (T).
