Sediment transport and morphology


To develop successful coastal and estuarine infrastructure projects requires the ability to predict the sediment transport and the resulting morphological changes along coasts and estuaries. An aspect which also is important when developing appropriate management options for existing coastal land due to typical annual climatic conditions or coastal disasters such as hurricanes, typhoons and tsunamis.

Infrastructure projects along the coasts include land development for tourism, development of ports and navigation channels as well as protection projects. Such projects can be affected by morphological changes such as land loss and flooding due to shoreline erosion, widening of tidal inlets, breaching of barrier islands or collapse of marine structures. Similar navigational channels may be affected due to sedimentation.

It is important that these problems are identified at the planning stage so that remedial measures can be evaluated and implemented before the cost of remediation becomes prohibitive.

Our approach is to develop engineering solutions based on a sound understanding of the physical processes and phenomena. These complex problems are investigated using a combination of field surveys, advanced simulation models (LITPACK, MIKE 21 and MIKE 3) combined with years of experience from carrying out projects wordwide.
