risk to coastal environments storm surges Flashcards
what is a storm surge a result of?
low pressure created by large weather events eg tropical storms
what do storm surges raise and what risk can this lead to?
raise sea levels leading to increased flood risk
what can the risk of storm surges be exacerbated by?
removing natural vegetation
global warming
overall answer this question with the mini ones. how does removing natural vegetation exacerbate storm surges in terms of mangroves?
mangroves are the most what ecosystems in the world?
what do they provide to the area?
common where?
why are they being destroyed?
why are mangroves an excellent method of coastal management?
what do they trap?
mangroves are the most productive and complex ecosystems in the world
provide protection against extreme weather events eg cyclones
common in the bay of bengal
land use pressure is why they’re are being destroyed
they can also keep up with global sea level rises of up to eight times the current rate
they trap sediment leading to accretion on the coastline, helping
protect communities from the potential impacts of climate change
how does global warming exacerbate storm surges?
the surface of oceans get warmer, it is predicted that the frequency and intensity of storms will increase , and so the severity of storm surges and flooding is also expected to increase
