Longshore drift plays a large role in the evolution of a shoreline, as if there is a slight change of sediment supply, wind direction, or any other coastal influence longshore drift can change dramatically, affecting the formation and evolution of a beach system or profile. These changes do not occur due to one factor within the coastal system ...
[1] [4] The movement of cuspate forelands is commonly explained by longshore drift acting as the main process. However, there have been observed cases where two cuspate forelands on the same shoreline have migrated in opposite directions, showing that longshore drift does not always provide a sufficient explanation for their migration.

Beach wrack or marine wrack is organic material (e.g. kelp, seagrass, driftwood) and other debris deposited at high tide on beaches and other coastal areas. This material acts as a natural input of marine resources into a terrestrial system, providing food and habitat for a variety of coastal organisms.
The endless cycle of swash and backwash and resulting beach drift can be observed on all beaches. This may differ between coasts. Rhossili in Wales is a low-energy shoreline. Probably the most important effect is longshore drift (LSD)(Also known as Littoral Drift), the process by which sediment is continuously moved along beaches by wave action ...
Coastal sediment supply is the transport of sediment to the beach environment by both fluvial and aeolian transport. While aeolian transport plays a role in the overall sedimentary budget for the coastal environment, it is paled in comparison to the fluvial supply which makes up 95% of sediment entering the ocean.

Hampton-on-Sea is located in Kent, England. It was at one time very popular for its oyster fishing and was very reliant on the sea. Hampton-on-Sea has undergone the effects of coastal erosion since before the 1800s. Hampton-on-Sea's coastal erosion worsened with the increase in global warming and climate change.
Coastal biogeomorphology looks at the interaction between marine organisms and coastal geomorphic processes. [2] Biogeomorphology is a subdiscipline of geomorphology . This can include not only microorganisms and plants, but animals as well.
The walls stabilise and deepen the channel which benefits navigation, flood management, river erosion and water quality, but can cause coastal erosion by interrupting longshore drift. One solution is a sand bypassing system to pump sand under/around the training walls.
