Toronto Overland Flood Visualization Using ArcScene - Hydrology and Hydraulics in Urban Areas Explain Reported Flood Risk

CityFloodMap.com overland flood risk analysis across the City of Toronto has been used in ESRI's ArcScene software to visualize at risk neigbourhoods and vulnerability zones where the correlation of urban overland / pluvial flooding and surcharged sanitary sewers resulting in basement flooding has been established. Flood risks exist beyond large regulated valley systems with a continuum of risk existing from river flood plain to individual building floor drain.




Additional visualization below includes identification of building structures within the estimated overland flood risk zone.
