Dredging is a necessary process for the maintenance of shipping channel depths and port facilities access. It is also carried out in the development works of marine infrastructure, primarily to create safe navigation route for teh vessels. Sediments removed from the seabed, termed dredged marine soils or DMS, are destined for disposal, either inland or in offshore containment. While various measures are introduced to minimize the negative impact of dredging on sea lives and marine ecosystem in general, less is being directed at managing the DMS for second lives. Categorised as a geo-wastes, DMS are generally consid-ered a soil of poor engineering qualities, i.e. low strength, excessively compress-ible, long term excess pore water dissipation leading to consolidation subsidence, as well as potentially tainted with contaminants with high human risks. As such, it follows that the materials require special characterisation and pre-treatment prior to being reused, especially for applications in close contact with human be-ings. Starting with a description of the emergence and history of dredging, the lecture then unfolds the dredging procedure and machinery involved, followed by outcomes of DMS characterisation study with a discourse on the geo-param-eters examined. Next concise accounts of the research works being conducted in the past decade with DMS from Malaysian waters are presented. With the spe-cific aim of giving second lives to the otherwise geo-wastes, summarised findings from the related experiments and field measurements are discussed, illustrating the latent potential of DMS in various civil engineering applications, especially as sound geomaterials for backfilling and reclamation projects.
