Positives and Negatives of flood management in the context of Mississipi flooding
Artificial Levees
Positives
Can stop water from rising too much while using limited resources.
Negatives
Do not prevent floods, An artificial Levee in one town will make floods in other towns in the same river much more severe
Example: Mississippi River
Dams
Negatives
Dam construction causes the surrounding area to be flooded.
dams can be very expensive
Positives: Can store water to supply drinking water in case of a disaster. Can Generate electricity.
Negative
could break and leave lands completely wet
could cause flood easily if it breaks
takes time to reabuild
also costs alot of money
Flood relief channels
negatives
if is too small then it wont be very useful and wont help protect against big floods
they are expensive
positives
they can protect things like highways or freeways from being damaged but that depends on how long it is and how deep it is
most of the time doesn't affect things nearby that much
can be applied in multiple places as there are less restrictions
flood walls
positives - Makes sure the flood water has no serious damage onto buildings and houses
they are also very easy to handle construct and place.
negatives
if the water rises to high the flood wall can be destroyed or the water could just rise over it, making it useless
if others don't have flood walls they make the water rise higher for areas near affecting others negativity
flood walls are very expensive
you can use flood walls in big and small houses
Afforestation
positives: It decreases erosion, it gives a habitat to animals, it can serve as recreation (a garden).
negative: Takes up space, takes long time to take effect
Land use zoning
Positives: Can target development in a certain area without having to worry about the risk of fooding. Saves lives and property. Can get rich soil from red zones WHEN SAFE.
Negatives: Decrease in space.
