Dredging
Dredging is a challenging and costly process for the operators of almost all ports and harbours. While navigation channels must be kept open, frequent maintenance dredging can be expensive. Coldwater's expertise in understanding and predicting sediment transport by currents, waves and ships can be key to optimizing operations or developing economical alternative approaches. Before an efficient and effective means to minimize maintenance dredging requirements can be developed, the factors that affect flows and sediment movements should be understood, including circulation and wave conditions, sediment supply/budget, and local and regional sediment dynamics.
Our portfolio includes dredging, channel alignment/re-alignment, sediment management, flow control structures, scour protection, and erosion hazard analysis. Our team are world leaders in the development and application of computer models and analysis techniques for sedimentation analysis. The results of our sediment transport research are used internationally to address all manner of sediment transport problems. PTM, our 'Particle Tracking Model' is distributed worldwide by Aquaveo and is used extensively by the US Army Corps of Engineers for both dredging and sediment transport studies.
