drainage

Drainage refers to the process of removing excess water from land or surfaces, typically through natural or artificial channels like rivers, pipes, or ditches. It helps prevent flooding, reduces waterlogging, and maintains soil stability and health. Proper drainage is essential for agriculture, construction, and urban planning, ensuring that water moves efficiently away from areas where it could cause damage or impede growth. Effective drainage systems are designed to manage water flow safely and sustainably, protecting both the environment and infrastructure.
