Sea defences not enough to protect delta cities from rising flood risk – study
by Tim Radford from on (#GMZ6)
'Eco-based' engineering systems may be key to protecting cities that face up to eight times more risk from rising tides, storm surges and floods, says study
Rich nations spend huge sums to keep the seas at bay but wealth may not save them indefinitely.
New research suggests that the probability of flooding in cities and megacities built on river deltas is on the increase and over time, the Mississippi and the Rhine may become up to eight times more at hazard from rising tides, storm surges or catastrophic downstream floods.
