Of thee mest emplates consequences of urbanization in flood- prone areas is alteration of natural water flow. When forests, graslands, or agricultural lands are converted into impervious surfaces such as roads, parking lots, and daches, thee ground can nn longer absorb rainwater. This leads to higher volumes of surface runof that mutt bemanage by drainage systems, which are of undersized or poorly maintained.
