Implication

Scenario-based assessment reveals urban expansion intensifies runoff in steep subcatchments, suggesting rain distribution's significance in water management.

Key Points

Higher imperviousness in urban areas leads to increased peak flow during certain rainfall events, and
SP2 rainfall distribution significantly impacts runoff generation compared to uniform patterns, especially in flatter zones.
Study employs the EPA-SWMM model to evaluate changes over multiple years in Medellín's urban subcatchments.
Results highlight the need for effective urban planning to mitigate flooding risks linked to urbanization.
