Abstract: Urban flooding has become one of the most critical challenges for cities worldwide due to climate change, rapid land-use transformation, and limited drainage capacity. This study presents a model-based assessment of alternative stormwater regulation strategies aimed at mitigating surface inflows and improving system performance in a densely built-up area of Mexico City. The methodology integrates a high-resolution corrected Digital Elevation Model (DEM) and two-dimensional hydraulic model to evaluate the effectiveness of stormwater regulation strategies combining conventional grey infrastructure with nature-based solutions. Results indicate that hybrid regulation measures combining green and grey interventions can attenuate peak discharges by around 50%, reduce runoff volumes, and decrease flood extents.
