Principles and guidelines for the environmental protection of drainage basins prone to flash floods: Experimental intervention in a pilot drainage basin

The second Chapter refers to the institutional and legislative framework, that is, the laws in force at the different levels, from local to global, in each partner\u92s country and concludes with considerations on optimal levels of coordination. Chapter III begins with the methodology recommended for the study of small-medium basins, based upon the previous work done by the same team1. It continues with the non-structural solutions (basin land-use plans and floodplain management, urban development regulations and constraints) for preventing flood hazards in the studied areas and the adopted structural interventions (sound and efficient environment-friendly engineering techniques, design and execution of structural works aiming at the protection of areas prone to flash floods). A schematic view of the criteria for the intervention alternatives is presented in Chapter IV. Chapter V and VI refer to ex-post evaluation and a glossary of the technical terms commonly used in Austria, Italy and Portugal, and in English. The Annex includes (under a separate volume), the application of principles and guidelines for flash flood prevention in the Civiglia Basin, described in the preceding project.Prem
