Hard Engineering (AQA A-Level Geography): Flashcards

Physical change to coast using resistant materials for protection

Redirects waves back to sea, reducing impact

Over £7,000 per metre

Large boulders placed in front of cliffs/walls

Small rocks in steel wire mesh cages

Trap sediment from longshore drift, build wider beaches

Starve downdrift areas of sediment, increasing erosion

Large dam-like structures preventing flooding in estuaries

Works against nature (unlike soft engineering)

Eight main types
