Abstract
Flood proofing methods and the associated techniques provide an effective option to enhance resilience in urban areas, under both commitments of long term mitigation planning and of emergency management. Flood proofing techniques are focused towards making a micro-scale support available to the community in order to hold its own from floods through an early active engagement. This involves not only a public commitment, but a private appointment too. Mortality rate, economic damage, cultural and heritage losses due to floods can be significantly reduced under detailed plan and concurrent, real-time, matching actions by both public administration and citizens. To date, the best-known techniques are those developed, adopted and promoted by FEMA in the Usa, although the widespread diffusion of the approach still remains far from a satisfactory coverage of flood prone areas, as shown by frequent disasters occurred in last few years. However, urbanization and building practices in the Usa are far from those, multifaceted that one encounters in European and Italian territories. Accordingly, one can adopt FEMA systems, standards, facilities and devices to flood proofing in our country very seldom, because of the huge difference in the urban, building, hydrographic, river training, climate and geomorphological contexts. Thus, a specific theoretical and technological effort must be payed to adjust the flood proofing approach to European countries. Flood proofing methods and techniques could offer a set of complementary and flexible actions that, under a cost to benefit approach, could sometimes provide better performances of that provided by traditional engineering works and, in many circumstances, it can be integrated into a multi-approach to the management of flood risk. Flood proofing encompasses a broad range of possible actions to reduce direct flood damage to buildings, settlements, infrastructures or entire neighbourhoods. It comprises several techniques with different complexity, to be arrayed in accordance with an accurate and detailed hydrological assessment of the potential flood scenarios (water level, flow velocity, soil properties, etc.) and to a specific appraisal of the urban setting, this including social issues. The paper presents a rational approach in order to develop flood proofing strategies within the Italian contexts. This includes classification tables, based on qualitative and quantitative indicators, useful to integrate flood proofing measures into the traditional engineering approach to flood mitigation.
