Summary: Natural disasters have become increasingly frequent. On January 17, 2020, the city of
Iconha, located in the south of Espírito Santo, suffered the biggest flood of all time,
causing significant damage, and leaving 1,919 people left their home, 58 homeless
and 4 dead COMPEC (2022). The objective of this work was to evaluate the intensities
of sub-daily rainfall occurring in the region of Iconha/ES, compare with the
precipitation, duration and frequency curves of the rain gauge station with daily data
and generate the hydrograph of the flood of the Iconha river, through the transformation
model rain on grid with two-dimensional hydrodynamic flow, considering the rain
incident in the river basin varying in time and space through the inverse square
distance interpolation method. The information and records confirmed the good
security of the model and together with the result of the simulated hydrograph, the
existence of distortions in the maximum flow monitoring data from the Iconha River
Fluviometric Station was confirmed. Therefore, it is recommended not to use these
data for studies of maximum flows, especially with high periods of returns, and it is
suggested to use a flood spot and a simulated flow model for adoption in future studies
and projects.
