Geosynthetic materials are used extensively in coastal engineering and protection projects. The modern geotextiles industry, in fact, emerged in the 1950s in response to flooding in the Netherlands and tropical storm damage in the United States. Since then, a large industry and innovative designs have come along. Geosynthetic tubes and containers provide dewatering and solids separation for large-... »

By ACE Geosynthetics – Taichung Harbor, located at the south side of the Dajia River outfall, suffered from siltation due to drifting sand. A silt deposition area between the harbor and the outfall had been established to trap drifting sand and prevented sedimentation from interfering with the navigation channel and harbor. However, increasing sand drift load led to saturation of the silt depositi... »
