With the help of more than $ 3 billion in funding from the federal and state government, Cedar Rapids is recovering and has taken significant steps to reduce future flood damage, with buyouts of more than 1,000 properties, and numerous buildings adapted with
flood protection measures.
A comprehensive risk assessment would determine flood hazard for individual structures by modeling watershed and floodplain characteristics at fine spatial scales; it would describe the varying levels of protection offered by all elements of a flood protection system and mitigation measures; and it would account explicitly for uncertainties, including those related to current and future flood hazard, structure value and vulnerability, and the current and future performance of
flood protection measures.
In poorer areas, such as the Mekong Delta in Vietnam, where there is very little capital available, it may make more economic sense to boost their economic performance and accept a degree of flood risk instead of pouring resources into
flood protection measures which have very little success anyway.»
The study said investment in
flood protection measures could help reduce the magnitude of overall flood losses in the future.
Throughout Germany, two thirds of the former floodplains have been lost to dikes and other
flood protection measures.
As the world warms, we will have to review all manner of basic assumptions to keep
flood protection measures robust, says Jim Hall

floods and seismic
measures on bridges which will provide long - term
protection from earthquakes and other natural forces.
On a more positive note, river
flood losses in Europe show a near - static trend (despite their increased frequency), indicating that
protection measures that have been implemented may have stemmed
flood losses.
«Unless we take different
protection measures, 5 million people will be exposed to coastal
flooding on an annual basis,» said Michalis Vousdoukas, a coastal oceanographer at the Joint Research Centre (JRC) of the European Commission and the lead author of the new study published in Earth's Future, a journal of the American Geophysical Union.
Direct subsidies are not invested in
flood protection but are often invested in
measures that merely maximise profit in the short term.
NFIP currently assesses
flood risk in terms of the probability and depth of
flooding, the economic value of the assets subject to damage, the vulnerability of the structure, and the performance of
flood protection and mitigation
measures.
It argues that investments should start with low - regret options, with
measures that tackle the weather risks that countries already face, such as increased investment in water storage in drought - prone basins or
protection against storms and
flooding in coastal zones and / or urban areas.
Measures include the rise of
flood protections, reduction of the peak flows through water retention, reduction of vulnerability and relocation to safer areas.
Further adaptation
measures to reduce the peak flow should make use of natural retention capacity upstream, while rising
flood protections should be seen as last resort, to compensate for the residual risk in areas where other options can not be implemented.
