Hard: Storage Areas
+Natural looking +No environmental damage -Large area of land needed -Only works when river is already flooded
1 of 10
Hard: Dams
+Can generate hydroelectric power -Expensive -Land is lost when reservoir is formed -Trapped sediment leads to erosion
2 of 10
Hard: Embankments
+Earth ones provide habitats +Concrete ones stop erosion +Can have paths on top for pedestrians -Earth ones are eroded easily -Concrete spoils the view -Often aren't high enough
3 of 10
Hard: Flood Relief Channels
+Can be used for water sports +People feel safer -Very expensive -Require large amounts of land which may be difficult to purchase
4 of 10
Hard: Flood Walls
+Quick and easy to assemble +Good in areas of limited space -Must be assembled well -Spoil views
5 of 10
Hard: Channelisation
+Long lasting +Protects immediate area -Increased risk of flooding downstream -Unnatural and visually intrusive
6 of 10
Soft: Warning Systems
+Cheap +Effective in warning people to move valuables -May not be enough time before flood -Sirens can be vandalised
7 of 10
Soft: Afforestation
+Cheap +Sustainable and good for environment +Prevent soil erosion -Conifers cause acidic soil -Dense plantations spoil natural looks -Increases risk of forest fire
8 of 10
Soft: Washlands
+Provides habitats +Cost effective as nothing is built +Soil is enriched -Large areas of land are flooded leading to a loss of productive land
9 of 10
Soft: Floodplain Zoning
+Cheap +Reduces risk of damage to property +Sustainable -Resistance from people due to lack of housing -Hard to enforce in LICs
