Presentation transcript:

A high energy coastal environment – Saltburn to Flamborough Head, Yorkshire How long is the stretch of coastline and what is it like? Map and description of its location Sediment sources Sediment cell number = Sub-cell number = From St Abbs, Scotland to Flamborough Why has some sediment come from sub cell 1d (offshore source)? Sediment from cliffs Sediment from rivers Geology North York Moors Flamborough Head Energy Dominant wave direction Fetch Where is wave energy highest and why? Energy - Why do rates of erosion vary? Shale and clay erosion rate Sandstones and limestone erosion rate Energy- Wave height What process operates from north to south?

Sediment continued Net increase in beach sediment 2008-2011 at Saltburn = Details of sediment at Filey Bay Examine figure 1.33 Describe where erosion is occurring and deposition What direction is the nearshore sediment moving in? Where is sediment input occurring? Cliffs Along the this stretch of coastline At Flamborough Between Saltburn and Robin Hood’s Bay Shoreline Platforms Give details of the shore platform at Robin hood’s Bay Headlands and Bays

Landforms on Headlands What features are found in Selwick’s Bay at Flamborough Head? Give details on stacks, geos, and blowholes. Why are there funnel shaped depressions on the cliff tops? Beaches Where are they found? Why do sediments accumulate slowly? Why does this stretch of coastline lack spits despite longshore drift operating? Supporting images/diagrams
