What happened Mappleton?
Mappleton and the cliffs are no longer at great risk from erosion. The rock groynes have stopped beach material being moved south from Mappleton along the coast. However, this has increased erosion south of Mappleton. Benefits in one area might have a negative effect on another.
What is hard engineering coastal management?
Coastal management Hard engineering management involves using artificial structures, whereas soft engineering management is a more sustainable and natural approach to manage coastal erosion. Geography.
Why is hard engineering bad?
Effects. Hard engineering can cause unintended environmental consequences, such as new erosion and altered sedimentation patterns, that are detrimental to the immediate human and natural environment or along down-coast locations and habitats.
What is the average rate of erosion at Kilnsea?
between Easington and Kilnsea, the rate of erosion was catastrophic; for more than 3.5 km. of coast the mean annual recession… exceeded 2.0 m., and in two places the rate was as high as 2.75 m.
Why are beach groins bad?
The negative impact of groins on downdrift shorelines is well understood. When a groin works as intended, sand moving along the beach in the so-called downdrift direction is trapped on the updrift side of the groin, causing a sand deficit and increasing erosion rates on the downdrift side.

How much do groynes cost in Australia?
It is anticipated that construction of a groyne at Shelley Beach would cost in the range of $300,000 to $500,000 allowing for mobilisation costs and inflation. A geotextile groyne should be considerably less expensive.
