Identify the hard engineering approach to river management described below. Cutting of meanders to create a more efficient channel better suited to the rapid transfer of water.

Dams and reservoirs

Flood relief channels

Embankments

Channel straightening

Correct! Wrong!

Identify the hard engineering approach to river management described below. New channels constructed to by-pass towns or other high-value land.

Channel straightening

Dams and reservoirs

Flood relief channels

Embankments

Correct! Wrong!

True or false? Constructing embankments involves raising river banks to create a larger cross-section enabling the river to hold more water.

True

False

Correct! Wrong!

Which of the following improves river navigation?

Flood relief channels

Dams and reservoirs

Channel straightening

Correct! Wrong!

True or false? Reservoirs silt up over time increasing its storage capacity.

False

True

Correct! Wrong!

Storage capacity is reduced over time due to the reservoir silting up.
