#erosion

A new seawall along the English Bay coastline in Vancouver, BC, designed as an alternative to a purely functional infrastructures by landscape architects Paul Sangha, working with a biologist and engineers.

In addition to the angular wall, plantings and strategically placed boulders create a more porous edge, slowing the flow of water and the deposit of sediment, and building up a new sand beach

The seawall is designed as a functional piece of infrastructure but also becomes a careful steward of the greater landscape.

Dunes pictured are at elevation of around 3000 metres (~9850 feet) above sea level, located in western part of the Himalaya Mountains.

Steep valley walls that stick out about 1000–2000 metres (3280–6560 feet) above the valley floor create a narrow corridor. This corridor captures major air mass movements which blow around the sands on the valley floor that eventually make up dunes.

Arch-shaped patters are sand layers within old dunes that have partially eroded. The erosion has exposed the internal structure revealing how the dune was constructed.

Wave rock around base of the Uluru monolith in Central Australia. An example of erosion-driven sculpting of the bedrock.

Coastal cliff erosion can create pillars when rock jointing or faulting are spaced at favourable intervals and angles. These will continue to be sculpted by the waves and often become tourist hotspots (such as the Twelve Apostles in Australia) or a refuge for sea birds, which can nest safely from predators.

Barron Falls is a result of plate tectonics at their best. Eastern part of Australia was separated from the current mainland, sinking under the sea, while leaving an escarpment on the mainland. This is the escarpment and it has been eroding since that time. Left are cascades which formed by river flowing over the edge of the escarpment.
