How does urbanization cause flooding
WebFlooding refers to the overflow of water from rivers, lakes or oceans onto land. It is a natural disaster that can cause widespread damage and destruction to property and infrastructure, as well as posing a significant threat to human life. Flooding may occur due to heavy rainfall, snowmelt, storm surges or dam failures. WebThis paper addresses the urbanization impacts on flood risks based on urban growth data and coupled flood models. Urbanization increases regional impervious surface area, which generally reduces hydrologic response time and therefore increases flood risk.
