‘It’s clear that the solutions that we employed in our approach to engineering in the 20th century are not aging well.’ As National Lead for the Engineering With Nature initiative, Dr Todd Bridges discusses how we must have a diversified solution set in which nature is a part of the solution.

Over the past decades, there has been a growing interest in exploring innovative ways to minimise the environmental footprint of coastal developments and in nature-based approaches for shoreline protection. At Mubarraz Island near Abu Dhabi (UAE), an international oil company beneficially reused ~12 million m³ of dredged material to protect pipelines, construct a causeway and create mangrove habitat to manage coastal erosion. This ‘Working with Nature’ approach has provided a cost-effective nature-based solution for shoreline protection, with added benefits for biodiversity conservation.

Can nature-based solutions be mainstream solutions? Nature-based solutions have obvious advantages but have not been embraced at wider scale. The barriers which can hinder wide-scale application and the topic’s relevance to the dredging community are discussed.

The Bacton Sandscaping scheme is a large-scale beach nourishment designed to protect the Bacton Gas Terminal from cliff and beach erosion while also reducing flood and erosion risk to the communities of Bacton and Walcott, buying the time they need for adaptation to coastal change.

This study examines which and, if possible, how much more ecosystem services are provided by the most recent nature inspired coastal protection project Prins Hendrik Zanddijk, in comparison with a traditional concrete and asphalt construction.

CEDA’s Working Group on Beneficial Use aims to inspire sediment stakeholders and practitioners by describing the importance of sediments in the context of sustainable development and sharing a curated selection of case studies.

Ecologist Patrick Meire has been researching the Scheldt for decades in the hope of implementing solutions which undo the damage caused by humans, industry and natural processes.

Building with Nature is an innovative approach that combines natural processes with innovative engineering methods to realise sustainable projects. Permeable dams are being utilised as part of a Building with Nature solution to help restore the eroding mangrove-mud coast of the Demak district in central Java, Indonesia.

Storms have always caused erosion along the coastline of Pevensey Bay (UK), but rising sea levels have made the situation critical. A Public-Private Partnership is creating a long-term, cost-efficient strategy to improve the situation.

Working with the Dutch Ministry of Transport, Public Works and Water Management, dredgers construct a dam as a means to prevent coastal erosion.

The book Dredging for Sustainable Infrastructure gives state-of-the-art guidance on how to design, implement and manage a water infrastructure project with a dredging component to project owners, regulators, consultants, designers and contractors.
