Impactos da ocupação urbana na permeabilidade do solo: O caso de uma área de urbanização consolidada em Campina Grande – PB

Abstract

The intense and unplanned urban occupation entails direct problems to the population. One of these problems is the decrease in the permeability index of soil generated by increasing paving that always accompanies the urban development of a region. As a result, the drainage system may experience overloads, once the infiltration capacity of the soil is changed and the paving increases the flow rate and the peak flows. This paper presents an integrated analysis of land use dynamics over the course of 32 years and the behavior of the urban micro-drainage system to the current scenario of occupation of Catolé and Sandra Cavalcante neighborhoods, in Campina Grande, PB. It verifies the disability of the micro-drainage system to accompany the accelerated growth of the region, leading in points of flooding that generate losses and discomforts to the population in more concentrated rain periods.
