Harnessing the Power of Nature for Stormwater Engineering

Nature is a powerful beast and we can learn a lot from natural system processes and adaptability. Natural systems are constantly changing and all too often, conventional “hard” engineering solutions are unable to cope with these long term natural processes. Looking to nature for inspiration can provide solutions that are adaptable and have the ability to “heal” themselves, as well has providing better aesthetic and amenity value. Designs using “natural” solutions can be simple, effective and efficient. And, with a little thought, we can also reduce maintenance requirements and provide ecological benefit, whilst still providing the required engineering output of protecting property and infrastructure.

This paper looks at two bank stabilisation projects and a treatment wetland project to demonstrate the benefits and challenges of integrating nature into engineered stormwater solutions.
