How does human development affect flood hazards?

Human development significantly affects flood hazards by altering natural landscapes and water flow patterns. Urbanization increases impervious surfaces, such as roads and buildings, which can lead to higher runoff and reduced natural drainage. Additionally, the construction of levees and dams can change river dynamics, potentially increasing flood risks in other areas. Poor land use planning and deforestation can exacerbate these issues, making certain regions more vulnerable to flooding events.
