assess wether storm surges pose an increasing risk for some coastlines

(Original post by BrDy)
ok not sure how much this is right but if by some coastlines they mean specific countries then you could talk about how human developments on and around coastlines have put them at increased risk.
e.g. removing mangroves for aqua farming which greatly increases flood risk and damage from storm surges because not only do they help to drain land they hold together and absorb impact from waves and storm surges which now have access to the bare coast and can cause considerable damage. Also in bangladesh the removing or lowering of levees to create more space for farming/living etc. which moves natural flood and coastal defences from a coastline placing it a far greate risk. This is an increasing risk because of new developments and also growing populations etc. and globalisation requiring more space and placing economic or commercial ventures over environmental values/safety (in regards to mangroves)

more generally rising sea levels results in an increasing risk, especially for low lying coasts, and the increase of more erratic and extreme weather events as a result of climate change.

on the other hand more investment into coastal defence systems, e.g. Deltawerken in the netherlands and I think there is better awareness of when events will happen so warning. BUT this is very much a varied effect- more economically developed nations will be better protected, while hte risk for LICs or NICs is likely increasing due to above mentioned points.

Hope some of this was helpful
