CADS Survey provides high precision reconnaissance and pre-construction surveys for environmental monitoring, volume of work calculations, feasibility studies, navigational depth surveys, independent pre/post dredge surveys, river training mapping, coastal erosion mapping, underwater objects search, and wrecks/obstructions. The highest accuracies underwater are achievable to search and identify objects anywhere on the seabed. At CADS, we can detect objects of 100mm and less. Ports and waterways in general are subject to siltation and occasional disposal of material, which accumulates on the seabed. This can hamper the navigation of waterways and/or influence the natural flow of water. Repeatable port, coastal, and river surveys are recommended to help predict sediment flows and environment impacts.
