In the article from Science Daily, “Natural Engineering Offers Solution against Future Flooding” by Newcastle University (2014), it was stated that “back-to-nature flood schemes”, which utilise the environment’s natural capabilities, can be an economical alternative to preventing and mitigating floods. Dr Mark Wilkinson, the research lead, also mentioned that winter rainfall and flooding occurrence would escalate in the future.
It was reported that several strategies of river-flow management have been exhibited in Belford, Northumberland, which illustrated the reduction of surface run-off and soil mineral depletion.
The article said that the Natural Flood Management (NFM) aspires to scale down the maximum water height or delay the arrival of the flood, adding more preparation time for response. This would be done by hampering the progress of water while working sustainably in tandem with the environment. Strategies include and storing, slowing and redirecting water and increasing soil infiltration. This proved to be much cheaper (~£200,000) in the Belford Scheme instead of a “full conventional flood-defence scheme” (~£2.5m). Mirroring Belford’s flooding situation, many other rural towns can also benefit from the NFM.

Overall, it was stated that the scheme was a triumph due to the backing and approval of the community, together with the comprehension of the “land and local environment”.
Science daily published Dr Mark Wilkinson research is purely in theory and is not proven yet are extremely risky and not practical. Giving the green light to go ahead will cause catastrophic tragic.
Research by Dr Mark Wilkinson ideas is insufficient to implement it to other places around the world as there is difference geography. Altering ways might cause severe consequence, for centuries Britain has been draining wetlands, reclaiming salt marshes and lining rivers with concrete banks and has driven rapid development. But as the climate changes and rainfall records are broken through the next century, there are concerns about the country’s ability to tackle the floods it will bring.
Today tried and tested system will no longer be sufficient. As sea levels continue to rise coastal populations, have always been threatened by flooding. Although over time we learned to build structures that can withstand against flooding. Sea level should increase by one meter or more by the end of the century, and no one knows how strong or climate will change. Engineers will continue to encounter problems in designing structures as they do not have enough information as compared to past centuries.
