Flood is a major natural disaster that has caused significant loss of life, property and economic development. Climate change may cause a further increase in the flood hazard and risks. Past disasters have triggered many governments to embark on disaster management, such as flood control, early warning systems and evacuation planning, A major worldwide contribution to disaster reduction is the Hyogo Framework for Action 2005-2015 which supports the integrations of the disaster risk considerations into sustainable development policies, planning and programmes at all levels, with special emphasis on disaster prevention, mitigation, preparedness and vulnerability reduction.
Infra Tech Pacific’s one of the key area of expertise is flood risk management and design of mitigation measures for disaster prevention and vulnerability reductions. Rivers and floodplains serve a variety of important natural functions including conveying water and sediment, storing flood waters, and providing diverse habitat. Floodplains, however, are also prime areas for agriculture, commercial and residential development and highways and bridges that may be prone to flood damage.
Infra Tech Pacific’s floodplain risk management seeks a balance between flood risk reduction and conserving natural functions.
