A GIS-Cellular Automata-Based Model for Coupling Urban Sprawl and Flood Susceptibility Assessment

In Urban Planning (UP), it is necessary to take under serious consideration the inhibitors of spread a settlement in specific direction. This means that all those parameters for which problems may arise future should be considered. Among these are geo-hazards, such as floods, landslides, mud movement, etc. study deals with UP taking into account possibility widespread flooding expansion areas. There large history Greece, accompanied by significant number disasters different types land use/land cover, financial cost compensation and/or rehabilitation. The area drainage basin Erasinos River Attica Region, where many and frequent flood events have been recorded. main goal this determine susceptibility area, possible factors decisive occurrence. Furthermore, also determined, scenarios precipitation urban sprawl scenario reference. uses Analytic Hierarchy Process (AHP) model SLEUTH, calibrates historical growth, using open cost-free data software. Eventually, maps were overlaid areas find vulnerable Following, three corresponding vulnerability maps, measure current space presented. results shown peaks moderate class susceptibility, while, third scenario, high values seem appear. proposed methodology specifically output can serve decision support tool assist planners hazard managers making informed decisions towards sustainable planning.
