- River Management Strategies (Hard Engineering)
- Enlargement
- bigger channel therefore room for more water so less likely to flood
- less flooding
- damages habitats
- increases velocity
- needs to be maintained
- expensive
- Bridge Widening
- prevents debris getting stuck which causes the dam to flood
- expensive
- ugly
- River Straightening
- moves water away quickly
- easier for development next to river
- increases velocity downstream
- no where for fishes to lay eggs in shallow bends of the river where the water is slow which is removed
- Levees
- water cannot spread even when it is flooding
- not much impact on river
- water cannot drain back into river or away if levees have overflowed
- if waters gets over, it will be very fast & destructive
- Dams
- creates recreation area
- generate HEP
- water flow is managed
- huge impact on natural river
- expensive
- ugly
- takes up lots of space
- Storage Areas
- water pumped out of the main channel & stored
- decreases volume of water
- takes up lots of space
- Enlargement
