Coasts: Hard Engineering

This film explores some of the Hard Engineering solutions used in coastal process management. Explore the different ways in which these solutions work, and the positive and negative aspects of their use. Earth Science - Geology - Learning Points. Natural processes such as, erosion, flooding and long-shore drift, cause problems for coastal dwellers. Hard engineering offers short-term, expensive solutions to the natural coastal processes. Seawalls reflect the energy of waves back into the sea and have a life-span of around 75 years. Less expensive alternatives to seawalls are available in the form of revetments, groynes and rock armour (riprap). A Twig Curriculum Film. Delivering key learning points.
