Effect Of Land Use And Low Impact Development Measures On Urban Flood Hazard: A Case Study In The Black Creek Watershed, Tommy Kokas
Electronic Thesis and Dissertation Repository
The number of flooding events in Canadian urban environments continues to increase, causing major environmental, economic and social consequences. This research uses the Black Creek watershed, located in southern Ontario, to investigate the impacts of urbanization on flood hazard and evaluate the effectiveness of various low impact development practices at reducing this hazard. A land use analysis indicates extensive urban growth between the periods 1949 and 2015, with extremely high imperviousness percentages existing today in the majority of the watershed. Historical hydrological simulations in PCSWMM show a significant increase in peak flows since 1949, but have now stabilized due to …
