Flood Warning, Forecasting and Emergency Response
This has, however, been achieved in developing countries such as Bangladesh Haque, ; Mirza et al. Locally recognised indicators may also be important when developed by coastal communities with a close relationship with the land and sea. Even once a warning system has been implemented, significant barriers to the effectiveness of this approach may still exist.
In a field study following the April cyclone in Bangladesh, Haque found that despite receiving flood warnings, a large proportion of the population took no deliberate emergency action. Therefore, a large segment of the population remained vulnerable. Three main factors were cited as reasons for failing to take action:. Fear of looting may be addressed by providing a denser network of smaller shelters to reduce the distance between homes and shelters and to allow better protection of property Haque, Improved law enforcement is also needed for better protection of private property during disaster events.
Fatalism typically stems from a sense of powerlessness to influence events. Disbelief of flood warnings may be due to past false warnings. It can be hard to forecast significant flood events due to their unpredictable nature. Therefore, it may be wise to implement a trade-off between the gains of advance warning when the hazard probability is low, and gains resulting from enhanced responses when the incidence of false alarms is reduced Haque, Additional reasons noted by Haque for failing to take action include disbelief that floods would occur in that area due to a lack of experience within living memory, over-filled shelters, the fact that shelters were crowded by men, which discouraged females users and finally, a lack of awareness of the limited amount of protection that homes would provide.
It is possible to implement flood warning systems together with other adaptation measures , as part of an integrated flood risk management plan.

Complementary actions could be part of a protect, accommodate or retreat approach. In London, flood warnings inform operation of a storm surge barrier and embankments have also been constructed along the majority of the riverside.
The costs involved in implementation of a flood warning system could be offset through the construction of multi-purpose shelters which could also serve as schools, health facilities and agricultural extension centres Haque, Technology used for detecting flood risk may also be used for forecasting rainfall when flood risk is low.
This could benefit agricultural practices in these regions. Norwich: University of East Anglia. Available from: www. Canberra: Emergency Management Australia.

Recent flood events in Europe, the USA and elsewhere have shown the devastating impact that flooding can have on people and property. Flood warning and forecasting systems provide a well-established way to help to reduce the effects of flooding by allowing people to be evacuated from areas at risk, and for measures to be taken to reduce damage to property.
With sufficient warning, temporary defences sandbags, flood gates etc can also be installed, and river control structures operated to mitigate the effects of flooding.
