Coastal management - low energy coastline, Studland Bay
Coastal landforms
Beaches
Wide, sandy beaches that are formed and maintained by the continous deposition of sand
-
-
Sand dunes
Behind beaches, sand dunes have formed over time due to the accumulation and stabilisation of sand by vegetation
These sand dunes are vital for coastal defense, absorbing wave energy and protecting inland areas from flooding
-
Crucial for coastal protection, absorbing wave energy and reducing erosion
Spits
-
Narrow landforms extend into the water, formed by the deposition of sediment carried by Longshore drift
The Studland Peninsula helps to create a sheltered area behind it, further reducing wave energy
Introduction
-
-
-
Low energy coastline, wave action is relatively gentle compared to high energy coastlines
-
Wave energy
Bay sheltered by the isle of purbeck and old harry rocks, resulting in lower wave energy
The fetch of the distance over which the wind blows across the water is relatively short = low energy environment
Costal processes
Erosion
-
However, during severe storms, some more vigorous erosion can occur
Deposition
Deposition is a significant process in Studland bay, contributing to the formation of various coastal landforms
-
Longshore drift creates beaches, sand dunes and spits
Ecosystems
Healthland
The sand dunes and surrounding areas support a rare healthland ecosystem, home to a variety of plant and animal species
Salt marshes
Sheltered areas, salt marshes develope
