How does urbanization cause flooding

WebFlooding can occur when the volume of stormwater exceeds the capacity of the stormwater drains. This can cause flooding in areas not necessarily close to waterways. Decreased soil moisture. Most urban surfaces are sealed, or impermeable. They prevent rainwater from soaking into the soil as it does in the natural water cycle. WebMar 3, 2024 · Floods are made more likely by the more extreme weather patterns caused by long-term global climate change. Change in land cover—such as removal of vegetation—and climate change increase flood risk. Extreme floods can be triggered by intense precipitation, longer duration, close repetition of precipitations or a combination of these.
