Factors that effect coastal Recession
Geological
Lithology
structures within rock
faults
joints
dips
folds
rocks within the same families have the different characteristics such as Limestone is softer than Sandstone
discodant VS condordant
coasts where band of rock that run parallel to the coast crate concordant coasts that are more straight than discordant coasts which forms when rocks run perpendicular to the coast
hard rocks Vs soft rocks
metamorphic and igneous rocks are harder than sedimentary rocks
Ecological
the role of plants are extremely important
holbeck hall
dune and salt marsh succession
pioneer species stabilise dunes and over the course of many years and eventually the dunes end up as full ecosystems
plants stabilise dunes then decay into humus
salt marshes are usually found between the tide lines and prevent the erosion of spits from behind by the easuary
roots break apart the layers of rock and are even more effective when a coast has lots of straight joints
human
Hard Engineering
sea walls
gabions and groines encourage dune growth
offshore breakwater (different part of littoral zone)
soft engineering
beach nourishment
increases natural defences
meteorological
