River dredging is a form of river restoration and river maintenance. Over time, sand, silt and debris flow downstream. Sedimentation is a natural phenomenon, which happens due to weathering, erosion and rivers carrying sediments. If not maintained, the materials accumulate and create a blockage. Consequently, this restricts natural river flow and makes the waters very shallow. As a result, rivers become inaccessible to larger ships. Additionally, during the heavy rain season, restricted river flow can cause flooding. Flooding may result in significant property damage, harm local businesses, and even be life-threatening.
Therefore, river dredging is necessary to maintain natural river flow and appropriate water depth to minimise the risk of potential disasters.
