Resumo:
In Brazil, urbanization usually occurs without planning, changing many regional
characteristics, causing changes in the hydraulic-hydrological behavior and problems such as
floods by urban runoff, for example. Engineering seeks to propose solutions that reduce or
mitigate the impacts caused by urbanization. As a result, the implementation of new
subdivisions should be reconciled with practices that seek to delay this type of flood and that
are economically viable. To this end, this dissertation analyzed the impact of adopting structural
and non-structural measures in the implementation of new subdivisions, aiming at decreasing
the peak flow and the technical-economic feasibility for four scenarios where the permeability
of the soil was varied in the subdivisions to be implemented in southern Minas Gerais. The
proposed control measures are paved with porous pavement, that all lots have a green area
corresponding to 10% of their total area and that all lots keep 5% of their area free for the direct
permeabilization of rainwater on the soil. The results are promising in terms of flows and
financial analysis can present alternative paths for the entrepreneur.
