holderness Flashcards
Characteristics
-rate of erosion at 1.8m a year due to weak boulder clay and makes it fastest eroding coastline in europe
-61KM long
-has naturally narrow beaches which provide less protection
holderness change
-10m erosion a year at great cowden
-retreated 4km in past 2000 years with 30 villages being lost
-spurn point has become more defined with curved ends
-more deposits behind spurn point spit have formed salt marshes
holderness control
-11.4km hard managed with 4.7 being sea wall and timber groynes
-political debate over holding the line or retreat
-mappleton had 2.9 million a year in losses before coastal management
-but has formed sandy beach and protected town pois such as the church
-mappleton had 2 million worth of rocck armour installed which while good has increased erosion rates south of mapleton significantly
conclusion
should retreat as coastal management is doing more harm than good with sssis unprotected and more exposed
