EFFICIENZA IDROLOGICO-IDRAULICA DI PAVIMENTAZIONI SEMIPERMEABILI PER IL CONTROLLO DEGLI ALLAGAMENTI PLUVIALI

The sustainability of the "water - city" combination is an interesting starting point for discussion and comparison within the various disciplines that address the theme of the urban environment, its continuations transformations, and the need for resilience to flooding. The technical and technological solutions today at disposition of those who deal with these problems, to address the issue of a sustainable relationship between water and the urban environment are multiple, some traditional and with consolidated experience, others innovative and more recent application in the field. Urbanization negatively affects education and flow propagation; in urbanized areas the rapid processes of transformation that have characterized recent decades have resulted in an increase in the degree of waterproofing of basins and, naturally, the increase in runoff and volumes generated in times of rain. The occurrence of events extreme meteor showers represents an ever-evolving phenomenon that has resulted in, more and more frequently, damage in urban environments where most of the vulnerable assets are concentrated. The Pluvial flooding is characterized by high spatial and temporal variability due to strong correlation with the microscale characteristics of urban catchments and therefore are extremely difficult to foresee. Alternative practices to the classic structural interventions for flood mitigation are the systems of sustainable urban drainage, also known as Low Impact Development (LID), or Best Management Practices (BMP), or Sustainable Urban Drainage Systems (SUDS). Their main task is to control white water through the use of low environmental impact technologies, which exploit e enhance natural resources and aim to maintain the water regime previously present of urbanization. Flooring was taken into consideration in this study permeable which allow the infiltration of rainwater into the various layers of the soil with reduction, also significant, of any surface flooding. The area of. was considered as a case study relevance, used as a car park, of the Forum shopping center in Palermo, an architectural complex for use commercial located between the Roccella residential district and the industrial area of ​​Brancaccio, whose Construction took place between 2008 and 2010.
