coastal erosion case study igcse

Coastal hazards can be either natural or human induced. Natural hazards include storms, flooding and tsunamis. Human actions cause a variety of issues as shown in the table below: Opportunities. Consequences. Impacts. Urbanisation and transport. Dredging and disposal of harbour sediments; changes in land use - ports, harbours and airports; road ...

Coastal management at Hornsea and Withernsea are examples of hard engineering solutions to coastal erosion. Erosion at Skipsea illustrates the human impact of erosion in areas where coastlines are not being defended. Mappleton is an excellent case study of an attempt at coastal management, which has a negative impact further along the coast.

Erosion forms bays in softer rock areas and headlands in resistant rock areas. Erosion on a headland leads to the sequential formation of a cave, arch, stack, and, eventually, a stump. Persistent wave action forms a flat, extensive slope at some cliff bases, known as a wave-cut platform.

Rain water can build up on top of the clay, causing the cliff to slump (Rotational cliff slumping). Pipes have been inserted into the cliffs to let out excess water. This is called cliff stabilisation, and is soft engineering. iGCSE Geography - Managing Coastal Erosion Case Study. 3.0 (2 reviews)

Main sea defenses (revetments) destroyed in 1990 storm. Government is enforcing a Do Nothing Policy of managed realignment. Narrow beach, unable to absorb much wave energy. Sea wall to the North at Cromer, Overstrand prevent erosion there and therefore reduce available sediment that could be deposited by LSD at Happisburgh.

The Holderness cliffs. These boulder clay cliffs are formed from material left by ice sheets. They are retreating at an average rate of 1.8 metres per year (ten times the rate in the chalk cliffs). This results from the combined effects of land (cliff-face) processes and sea (cliff-foot) erosion. On land, rainwater enters the clay and the ...

The previous ice age (18,000 years ago) released large amounts of glacier deposits (boulder clay), which extended the Holderness coast. This form of glacier deposit is extremely vulnerable to erosion. Coast has eroded by 4km; 30 villages lost to sea; hundreds of sq.km of farmland. Large amounts of revenue generated from tourism as an attractive ...

Lyme Regis Case Study of Coastal Management. Lyme Regis is a small coastal town on the south coast of England. It lies on the western edge of the Dorset Coast and forms part of the Jurassic Coast, a World Heritage Site famous for its fossils and coastal landforms. The town is a popular tourist destination in the summer.

Sometimes coastlines are left to erode rather than using coastal management methods. This is often in cases where there is not anything on the land that is being eroded which is economically worth protecting. Holderness Coast - Coastal erosion and management case study. The Holderness Coast is one of the fastest eroding coastlines in Europe.

This document discusses a case study about cliff erosion and asks what can be done to manage the impacts of coastal erosion. Management strategies mentioned include those used at Muriwai, Omaha, or Kohimarama Beach to address erosion issues, such as installing seawalls, replenishing sand, or relocating infrastructure further inland. 1.

Happisburgh Case Study. Happisburgh (pronounced "Haze-bro") is a settlement located on the Norfolk coast, eastern England. It has a population of around 1400 people in 600 houses. Although now a coastal village, this was not always the case. When founded over 1000 years ago, there was another village separating Happisbourgh from the sea.

Coral requires sea surface temperatures of 17-33°C to grow. It also requires 30-38 parts per thousand salinity and clear water. They're mainly located in the Indo-Pacific region and the Caribbean Sea. These vibrant ecosystems are teeming with various marine life and are known for their high biodiversity. Around 25% of the world's sea fish ...
