Description:
The southeast of Mexico City is one of the last areas of environmental importance for the
region. However, rapid urban expansion has led to a runoff increase in the presence of intense rainfall.
This situation is common to many peri-urban centers close to large cities, where the urbanization
of previously green areas has had a direct negative influence on the hydraulic structure. This work
proposes a study that combines hydrological analysis for the definition of precipitation scenarios
with hydrodynamic simulations based on the current land use. Reconstructed flood scenarios show
that the runoffs descending from mountainous areas flow into cemented channels with hydraulic
sections and characteristics not adequate to drain specific discharges that can reach 0.90 m2/s and
water depths of the order of 2 m, caused by extreme weather phenomena, determining flooding in
nearby areas. Runoffs are also intensified by the presence of non-urbanized open spaces in a state of
abandonment, whose soil does not favor infiltration and promotes the flooding of residential centers
with water levels higher than 1 m. The results indicate an urgent need to adopt actions to reduce
flooding and favor infiltration in an area of the city that is also important for aquifer recharge.
