How do human activites cause a flood?

Answer 1

Human activities can exacerbate flooding through urbanization, which increases impervious surfaces like roads and buildings, leading to reduced natural infiltration of rainwater. Deforestation and land clearing diminish the land's ability to absorb water, while poor agricultural practices can lead to soil erosion and increased runoff. Additionally, the construction of dams and drainage systems can disrupt natural water flow, sometimes resulting in localized flooding when these systems fail or are overwhelmed. Overall, these activities alter natural landscapes and hydrology, increasing the risk and severity of floods.
