The word ‘catchment’ refers to an area from which water is collected, often into a reservoir, river, or ground. It can also denote a drainage basin or watershed where rainwater or melted snow flows and is gathered. In a broader context, ‘catchment’ can be used in fields like education or health to describe the area from which a population is drawn or served, such as the demographics of students attending a school or patients served by a healthcare facility.
