Hard engineering examples bbc
Examples of hard engineering include: • Groynes – Low walls constructed at right angles to retain sediments that might otherwise be removed due to longshore drift. These structures absorb or reduce the energy of the waves and cause materials to be deposited on the updrift side of the groyne facing the longshore drift. • Seawalls – Seawalls are constructed to protect coastlines against wave attack by absorbing wav… WebWhat is hard engineering examples?
