Abstract

The form of land occupation in cities, resulting from urban patterns that do not dialogue with the physical environment, has been responsible for impacts on the hydrological cycle due to excessive waterproofing that contributes to the reduction of water infiltration and increased surface runoff. In this context, the importance of analyzing and defining urban design methodologies that promote water-sensitive urban patterns is highlighted. The present work studies the conceptual foundations that explain the functioning of the hydrologic cycle to identify urban patterns that reduce the superficial space and the impacts on the physical and built environment in the cities. The method used is: (i) Simulation of runoff behavior in a pre-urbanization area, (ii) simulations carried out in an urban plot with a traditional model allotment project with a dispersed urbanism pattern, and (iii) simulation of the same fraction using water-sensitive urban patterns previously studied. As a result, it was obtained that the surface runoff is greatly reduced with a proposal for water-sensitive urbanism, confirming the relationship between urban design and its ability to ensure aquifer recharge.
