Jackets and floors
of structures that have the ability to drain the water and
send it, by infiltration to the lower layers of the soil,
have relevance to ease the flooding caused mainly by the
increase in number of dwellings, and the growth of
waterproof coatings, and consequent deficiency in urban
drainage. This study evaluated the effectiveness of
permeable pavements in reducing runoff, by comparing the
experimental simulations flow generated in various kinds of
floor. The comparative analysis between the permeable
pavements and conventional allowed a study to better
occupation of the sub-basin St. Mary Magdalene in the city
of São Carlos, SP. From the feasibility study of permeable
pavements, the flow calculation, four scenarios were
developed with four types of permeable pavements, simulating
the use of these new materials in urban expansions possible
according to the Master Plan of the city. With the results
obtained in the simulations of the current situation and the
other four scenarios, permeable materials have a flow less
than conventional materials and show that streets and
sidewalks rather contribute to runoff and should be used
primarily for stage areas urban expansion, due to the ease
of deployment and its benefits to the environment. Despite
the cost analysis proves unfavorable to the implementation
of permeable pavements, it is concluded that the
environmental benefits and in improving the quality of life
are unmatched, and led to a degree of extreme importance in
the cost calculation benefíciopara a later occupation
sub-basin under study.
