Flood Prevention and Sustainable Spatial Planning. The Case of the River Diakoniaris in Patras Authors: D. Vespiniadou, E. Athanasopoulou

The danger of floods from overflow of rivers that crosses urban regions is a frequent phenomenon that concerns many of European countries. In the framework of Sustainable Spatial Planning arise some serious questions for the way that should such phenomena be handled, apart from the purely hydraulic conventional interventions. Noteworthy that at his flow a river runs through usually at all the length completely dissimilar regions as long as they concern in geomorphology but also their urban characteristics (urban density, existing land uses etc). Through the experience of other countries, different approaches in institutional and urban metres will be studied. Also, the possibility of redesigning the flood region of urban rivers will be examinated, proposing suitable uses per case. The article will investigate the example of Diakoniaris River in Patras/Greece It is a river that crosses the coastal city of Patras in length of 4 kilometres roughly in address E-W, and in the past (1962,.2001) he has created catastrophic floods. Our approach focuses on the suggestion of proposed institutional regulations but also methodological approaches that concern in the flood-preventing protection of urban regions
