Summary |
The main goal of the SATFLOOD project is the digital mapping of the urban sprawl in the island of Cyprus with the application of digital image analysis techniques to high spatial resolution satellite images (Quickbird, Ikonos, Landsat, etc). As a case study, the Potamia catchment area in the broader area of Nicosia–Cyprus has been selected. Advanced radar satellite images (ERS, ENVISAT) are used to record in detail the past flood zones of the local drainage network. Moreover, sophisticated algorithms concerning land use changes and urban expansion are developed. Also, different kinds of spatial and attribute data such as geological, cadastral, urban planning, aerial photos and multitemporal rainfall data are inserted and analyzed in GIS environment. Concerning hydraulics, dominant features of the studied channel such as depth, water perimeter, hydraulic radius and slope are calculated through the use of sophisticated hydraulic–hydrological models, such as HBV and MIKE-SHE. A Digital Elevation Model of high spatial resolution is created through the use of Laser Scanner and Global Positioning System (GPS). Flood risk assessment maps are constructed in GIS environment, in order to indicate the possible flood high risk zones. Through this multidisciplinary approach, the present and the past regime of Potamia catchment area is under assessment. The target is to develop predictive models that can be utilized by the local authorities as road maps for a future sustainable urban planning. |
