Flood risk: connect the river and the settlement

01 · Hazard

Heavy rainfall, river discharge and channel conditions can generate flooding.

02 · Sediment and channels

Deposition, erosion and channel shifts alter local risk over time.

03 · Exposure

People, homes, farms and infrastructure may lie in affected areas.

04 · Vulnerability

Housing, poverty, access, health and preparedness influence harm.

05 · Risk reduction

Warning, evacuation, land-use choices and context-specific engineering can reduce losses.

Connect the branches

Flood hazard is not identical to disaster risk; human exposure and vulnerability matter.

Avoid the exam trap

An embankment is not a universal permanent solution without maintenance and wider catchment planning.

Test yourself: Can the same flood depth cause different losses in two settlements?

Yes. Exposure, vulnerability, preparedness and recovery capacity can differ.
