Costs and benefits of coastal management strategies

Using GIS to visualise the impact of physical and human processes on coasts

This unit, comprising of three variants, teaches pupils about processes and landforms associated with coastal, river and glacial landscapes. Pupils will learn about the formative processes involved in creating distinctive landforms and of the need for management.

Coastal, river and glacial landscapes

{{}} engineering means making use of natural processes to reduce erosion and flooding in a way that minimises environmental impact.

The cliffs at Lyme Regis are made up of an unstable mix of layers of thin __________ and softer __________ layers.

Tourism is the biggest industry in Lyme Regis for a number of reasons:

in 1995 sea walls and rock armour constructed

beach nourishment and cliff stabilisation completed in 2007

cliff stabilisation and new concrete sea wall in front of old (2014)

strengthening of “the Cobb”, a wall and walkway (2025)

Dorset Council’s Environmental Improvement Strategy for Lyme Regis has included both hard engineering and soft engineering strategies over its five phases (stages):

Environmental groups are often opposed to {{}} strategies like sea walls and groynes, arguing they disrupt natural processes and damage ecosystems.

__________ engineering uses artificial structures to protect coastlines from erosion and flooding.
