Urban flooding is an increasingly
important issue. Disaster statistics appear to show flood
events are becoming more frequent, with medium-scale events
increasing fastest. The impact of flooding is driven by a
combination of natural and human-induced factors. As recent
flood events in Pakistan, Brazil, Sri Lanka and Australia
show, floods can occur in widespread locations and can
sometimes overwhelm even the best prepared countries and
cities. There are known and tested measures for urban flood
risk management, typically classified as structural or
engineered measures, and non-structural, management
techniques. A combination of measures to form an integrated
management approach is most likely to be successful in
reducing flood risk. In the short term and for developing
countries in particular, the factors affecting exposure and
vulnerability are increasing at the fastest rate as
urbanization puts more people and more assets at risk. In
the longer term, however, climate scenarios are likely to be
one of the most important drivers of future changes in flood
risk. Due to the large uncertainties in projections of
climate change, adaptation to the changing risk needs to be
flexible to a wide range of future scenarios and to be able
to cope with potentially large changes in sea level,
rainfall intensity and snowmelt. Climate uncertainty and
budgetary, institutional and practical constraints are
likely to lead to a combining of structural and
non-structural measures for urban flood risk management, and
arguably, to a move away from what is sometimes an
over-reliance on hard-engineered defenses and toward more
adaptable and incremental non-structural solutions.
