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 ...
Global warming is causing a rise in sea level, more intense and frequent storms, and an increase in ocean temperature and precipitation levels. Another reason Hampton-on-Sea had such a horrific case of coastal erosion is due to an increase in the frequency and the intensity of storms it experienced. [ 11 ]
According to the World Economic Forum, an increase in drought in certain regions could cause 3.2 million deaths from malnutrition by 2050 and stunting in children. [246] With 2 °C warming, global livestock headcounts could decline by 7–10% by 2050, as less animal feed will be available. [247]
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.

This solution entails beach nourishment (creating recreational area by filling with sand), and further beach expansion and prevention of beach erosion caused by longshore drift and coastal development hazards. The design makes use of a shorter groyne slightly inclined toward the beach in the same direction as downdrift, with a series of ...
Destroyed homes and collapsed power lines have peppered a section section of Los Angeles County coastline that is rapidly merging with the ocean, prompting an emergency declaration, a buyout ...
Another common cause of isostatic change that can result in a submergent coastline is tectonic action. [2] Events such as earthquakes or volcanic eruptions may cause land subsidence therefore causing isostatic sea level increases. [2] Eustatic sea level rise can also be caused by many reasons. One common reason is thermal expansion. [2]
