Extreme storms can cause devastating erosion and leave beachfront houses teetering on cliff edges. But new research finds storms might also help replenish beaches by bringing in new sand from deeper waters.
Mayors and governors of the world’s coastal cities call relevant stakeholders, building on the «Cities Race to Resilience» campaign, to scale-up mitigation and adaptation to limit the impacts of sea level rise on cities, communities and their territories.
A Nature-published study led by scientists at the National Oceanography Centre (NOC) has quantified for the first time that contributions from human activity may have already altered the likelihood of storm surge extremes.
Bangladesh and the Netherlands are both situated in low-lying lands, making them prone to floods. As a result, both countries have found benefits in cooperation around flood control and water management.
This study presents and implements a framework for calculating optimal risk-informed design heights. The work identifies levee and floodwall design heights that minimize the total system cost and expected flood losses over 50 years.
