A Seawall in Canada Takes a Different Approach to Combating Coastal Erosion

A SEAWALL IN CANADA TAKES A DIFFERENT APPROACH TO COMBATING COASTAL EROSION Meanwhile, in Vancouver: Those familiar with Galveston’s frequent sand replenishment projects likely know that flat seawalls can exacerbate beach erosion by reflecting wave energy that would dissipate more readily in a natural sandy setting.  In response so-called king tides pummeling the coast of Vancouver, a Canadian landscape artist collaborated with a biologist and engineers to address beach erosion in a new way. Blending principles of ecology, hydrology, and aesthetics, Metamorphous incorporates boulders, plant life, and an angular a steel structure intended to rust away altogether in less than 100 years. The functional public art piece slows the flow of water as it rushes inland, causing sand to be deposited on the beach for the first time in resident memory. [Citylab]
