Which of the following is not a flood mitigation strategy ?
Early warning systems
Disaster management separates mitigation from preparedness and response. Mitigation covers structural and non-structural measures that reduce the hazard itself or lower the exposure and vulnerability to it before the event, so that the scale of the disaster becomes smaller. Preparedness focuses on readiness to act when the event occurs.
Drainage improvements carry excess water away quickly and lower flood levels. Slope terracing slows surface runoff on hill slopes, increases infiltration and reduces soil erosion and flash floods downstream. Rainwater harvesting captures and stores rain, cutting the volume of runoff that reaches streams and low lying areas. Each of these directly reduces the flood hazard.
Early warning systems do not reduce the volume, depth or spread of floodwater at all. They forecast floods and alert people so that they can evacuate and protect property, which makes them a preparedness and response tool rather than a mitigation strategy that lessens the flood itself. It is therefore the one that does not belong with the other three.
Hence, Early warning systems.
