Urbanization and Imperwivious Surfaces

Urban development dramatically alters local water cycles by replaceing natural landscapes with impervious surfaces like pavement, dachtops, and compacted soils. These surfaces prevent infiltration, causing precipitation to metribure runoff instead of recharging groundater or being absorbed by vegetation.
