Hard and soft engineering water on the land

?
What are the hard engineering strategies?
Dams and Reservoirs, Channel straightening
1 of 8
What are the advantages and disadvantages of Dams and reservoirs?
Store water, which can be used for drinking and HEP. However, expensive, deposition in the reservoir leads to land becoming less fertile.
2 of 8
What are the advantages and disadvantages of channel straightening?
Water moves out of area faster because it doesn't travel as far. However, flooding may happen downstream instead, more erosion downstream
3 of 8
What are the soft engineering strategies?
Flood Warnings, Preparation, Flood plain zoning, 'Do nothing'
4 of 8
What are the advantages and disadvantages of Flood warnings?
Reduces impact of flooding as people have time to prepare/evacuate. However, Warnings don't stop flood, if there are too many warnings insurance could be difficult, people may not have access to warnings
5 of 8
What are the advantages and disadvantages of Preparation?
Impact of flooding reduced, However, doesn't guarantee safety from flood
6 of 8
What are the advantages and disadvantages of flood plain zoning?
These are restrictions preventing building on flood plain, which means risk of flooding reduced, and less impermeable surfaces created. However, this doesn't help for areas already built on
7 of 8
What are the advantages and disadvantages of 'do nothing'?
Makes farmland more fertile, however risk of flooding still present
