Flooding increases with economic and urban development.

As human settlements grow and develop, they often replace natural permeable surfaces like soil and vegetation with impermeable surfaces like concrete and asphalt. This leads to faster runoff during heavy rain events, which can cause flooding. Additionally, urban development often involves altering natural waterways and drainage systems, which can further increase the risk of flooding. Economic development can also contribute to flooding by increasing the demand for construction and infrastructure development in flood-prone areas.
