dc.description.abstract |
This research evaluates the effectiveness of planning and building regulations in coping with urban flooding
under different precipitation scenarios. Accordingly, the study simulated seven alternative scenarios considering
the variations of precipitation, plot coverage regulations, and Low Impact Development (LID) options. The study
utilized open-source geospatial software to model different surface runoff scenarios. Then the effectiveness of
those seven alternatives was assessed by utilizing the Analytical Hierarchy Process (AHP) technique to evaluate
their sustainability in urban design. The results revealed that the plot coverage regulations are effective in
managing floods during average rainfall events, and LID-based infrastructure solutions are effective during
moderate rainfall events. Nevertheless, none of these solutions were solely adequate during extreme rainfall
events. Regardless of the response to extreme rainfall occurrences, the practitioners’ opinion was in favour of
green roof adoption and plot coverage regulation considering their effectiveness in managing more frequent
average rainfall events, and the overall sustainability in maintaining the balance of urban hydrological pathways.
Accordingly, the findings of the study can be utilized as a guide to the decision-making process in urban planning
and design, and to formulate sustainable planning regulations and guidelines to cope with urban flooding under
the precipitation uncertainty. |
