This programme considers the moving patterns of a changing coastline and sea floor topography as currents and waves continually shift sediment from one place and deposit it elsewhere. desperate and... expensive attempts to protect some coastlines may come to nothing if the science of sedimentary transport is ignored. The programme shows scientists deploying seabed instruments from a research vessel in the North sea off the Holderness coastline just north of Spurn Head, on eof the most heavily eroding areas of the UK. Much of the sediment from these cliffs ends up further down the coast and some is swept across to the Netherlands ending up in the Dollard estuary at the border with germany. The barrier island of terschelling in the Wadden sea is the focus of a European project on protection of the coastal zone by replenishment of offshore sand bars. In the Dollard a large platform has been constructed so that the movement of sediment during tides and storms can be measured by instruments suspended in the water column from the platform above. Long term measurements will show how mud is transported in and out of the estuary from the North Sea throughout all the seasons.
