Historically, many river shorelines were stabilized and hardened with concrete and steel to protect developments from flooding and erosion, or to accommodate navigation and industry.
Today, in place of concrete and steel, designers put vegetation, stone and other materials that soften the edge while maintaining a stable shoreline, a process known as soft shoreline engineering.
The technique requires use of ecological principles to reduce erosion, keep the shoreline intact, restore habitat, improve public access and make the shoreline look attractive.
