- The shape and form of the coastline is known as coastal morphology
- This is influenced by the rock type (geology) and structure
Concordant coastlines - examples
Dorset, UK
- An example of a concordant coastline can be found in the area around Lulworth Cove in Dorset
- More resistant Portland Limestone runs parallel to the sea with less resistant Purbeck Limestone and Wealden Clay behind it
- The formation of coves has occurred where the water has broken through at weaker points in the Portland Limestone

Dalmatian coastline
- The Dalmatian coast in Croatia is another example of a concordant coastline
- Formed as a result of tectonic forces and sea level rise
- Tectonic activity forms anticlines and syncline which run parallel to the sea
- Sea level rise after the Devensian Glacial then flooded the synclines leaving the anticlines standing above the water
- The result is a series of islands which run parallel to the coast
Example of a Dalmatian coastline
Haff coastline
- Located along the southern Baltic coastline
- During the Devensian Glacial large amounts of sand and gravel were deposited offshore
- After the glacial period had ended the material was then deposited nearer to the land by constructive waves
- This formed bars across bays and river mouths trapping the water behind to form a lagoon (Haff)
- These are a feature of low-energy coastlines
