Flood - GCSE Geography Definition

A flood occurs when an area that is usually dry becomes covered with water. This may happen because of heavy rainfall, overflowing rivers, or melting snow. In Geography, floods are important to study because they can cause damage to homes, roads, and the environment, and affect people's lives. Floods can happen quickly after a huge storm, or slowly when a river swells over time. People often try to manage floods by building barriers, like levees and dams, and by planning where to build homes and cities to keep them safe from floodwaters. Understanding floods helps us to prepare better and reduce their impact on communities.
