Recomendações técnicas para amenizar os impactos causados pela impermeabilização dos solos na implantação de novos loteamentos

Abstract

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.
