Erosion and sediment transport

Modelled bathymetry due to both wave and current induced sediment transport (Jerba, Tunisia)

Erosion and sediment transport is a main challenge for most coastal nations with sandy beaches. Small and apparently insignificant development of the beaches may have great impacts on the shoreline. Erosion and sediment transport are generated and maintained through an interaction between waves and currents, and the sands occur as suspended materials as well as bottom loads.

Advanced numerical modelling tools based on 3-dimensional current and wave models are used to predict erosion and shoreline changes due to sediment transport, often supplemented by field measurements and physical model testing.
