Increased impervious surface area is a consequence of urbanization, which exert multiple pressures on the hydrologic cycle. Specifically, increase in impervious surface result in increased hydraulic efficiency in urban catchments, and can substantially decrease capacity for a given landscape or region to infiltrate precipitation, with a concomitant increase in the production of runoff, shorter times of concentration or lag times and decreased groundwater recharge. Urbanization also has indirect effects on downstream flooding and on aquatic ecosystems.(Download PDF) (Export to EndNotes)
