Urban Rivers

Urban rivers regularly incur logistical complications due to the proximity of development and increased surface runoff, leading to flashy and constrained watercourses. Traditional hard engineering solutions are frequently used within urban areas, consisting of sheet piling, rock armour and gabion baskets. Hard engineering has a detrimental impact on the riparian habitat however and is frequently not necessary.

Salix’s bioengineering products can often be used as a direct alternative to hard engineering, frequently providing better erosion protection whilst allowing vegetation to establish in urban environments.

Bioengineering products require less material than hard engineering and are quicker to install, making construction more effective in urban areas.
