Key Elements of Flood Disaster Management 2
23 Key Elementsof Flood Disaster Risk Management and Flood Plain DelineationA change to proactive Management ofnatural disasters requires an identification ofthe risk, the development of strategies toreduce that risk, and the creation of policiesand programmes to put these strategies intoeffect. Risk Management is a fundamentalactivity geared to the evaluation of schemesfor reducing but not necessarily eliminatingthe overall risk, as in may cases risk cannotbe entirely eliminated. Figure 8 provides aschematic of the steps associated with riskassessment and Management . It includesassessing the potential for a hazard to occurand a vulnerability analysis to provide anunderstanding of the consequences shouldan event of a certain magnitude andfrequency occur. Based on this initial work,various mitigation measures can beevaluated to assess their ability for reducingrisk exposure. Based on a thorough riskassessment, Disaster Management plans andspecific mitigation measures can beidentified.
