Abstract
The effect of climate change and the growing world population are together
increasing both the chance of flooding and the consequences. There is mounting
recognition that reliance on structural flood defences alone may be neither
sufficient nor sustainable in the long term, particularly in low lands.
In Italy, in the wake of the floods that plagued the northern part of the country
in the fifties and sixties, a process was set in motion aimed at developing a new
integrated approach to water management, at the catchment level, suitable for
coping with water related disasters.
In this context, three case-studies of flood risk management and hazard
assessment are featured: two related to the Po catchment and the last to the
Basento river in the Basilicata Region. After describing the methodologies,
which differ in the application effort required and in the accuracy expected, the
paper focuses on both the results achieved and the reliability of the procedures
applied. Management issues are approached under four general headings:
planning, technical, operational and institutional.
Although the cases differ with respect to the flooding problems they
encounter, some common issues emerged: the challenge of translating a riskbased
approach on a basin-wide level into concrete measures, harmonizing
flood-risk management policy with spatial planning and institutional
cooperation.
Keywords: flood management in Italy, new policy approach, country casestudies.
