Gabions at Studland Beach, Dorset
Gabions counter erosion on beaches, usually under soft cliffs such as limestone and sandstone, or they protect roads and paths next to the beach. Lots of them in soft calcareous and slatey southern England: above, Studland Beach in Dorset, tidy genteel gabions made by a masonry culture – they look like dry stone walls. Below, rough gabions in rough, granitey Scotland.
Duncan Astley. Gabions at Loch Hourn, Corran, ScotlandGabions are transparent to water, but obstruct larger things: sand and rock. A near-perfect solution, water is not thwarted, it comes and goes, but in a diminished way, its force absorbed by the gabion. The fill would be formless and weak if not held in place by the wire cage which, with the lightest of touch, forms a fighting unit of rubble.
