Abstract: Flood risk is an issue of great importance that currently has taken on more considerable relevance as extreme events are increasing and generate significant economic and social losses globally; in most cases, floods only present negative results to the exposed population, as happens in the city of Morelia, which is why it is required to generate a two-dimensional hydraulic model that allows delimiting the areas susceptible to flooding in the town. Sixteen streams that make up the fluvial drainage network of the city of Morelia were modeled, from which it is highlighted that under natural conditions, the Rio Grande, which is the main tributary of the city, generates affectations in areas topographically lower than it, which together with the runoff of these areas, which by itself causes overflows, magnifies the problem, generating significant economic losses in areas located in flood risk zones. Modeling the system's current situation helps us understand the problem and find the vulnerable areas to propose mitigation measures for these events.
