Urban flooding is a major challenge in rapidly urbanized cities due to inadequate drainage systems and increasing impervious surfaces. Extreme rainfall events can overwhelm urban infrastructure, causing severe economic and environmental damage.
This study evaluated the drainage network in a high flood-risk area of Erbil using the EPA SWMM hydraulic model. A 100-year rainfall event was analyzed through rainfall-runoff simulations. Initially, 25% of drainage nodes experienced flooding due to inadequate conduit capacity. The proposed design increased conduit diameters, node depths, and modified sub-catchments to improve system performance. Results showed complete elimination of flooding, reducing flooded nodes from 25 to zero and improving drainage efficiency. The study recommends implementing these infrastructure upgrades and continuous maintenance for sustainable flood management.
