👉 Drainage refers to the process by which water is removed from the surface of the Earth and transported away, typically through natural systems like rivers, streams, lakes, and groundwater. This process involves precipitation, infiltration into the soil, and runoff over land surfaces. Effective drainage is crucial for preventing flooding, maintaining soil moisture, and supporting ecosystems. It can be managed through natural landscapes, such as wetlands and forests, or engineered solutions like drainage pipes and canals, ensuring that water flows efficiently and does not overwhelm areas, thereby protecting both human infrastructure and natural habitats.
