A catchment area refers to a geographical region or area that is defined by natural boundaries, such as rivers, mountains, or coastlines, and is used to collect and channel water into a specific body of water, such as a lake, river, or reservoir. It is also commonly used to describe the area from which a particular institution, such as a school or hospital, draws its clientele or population. In this context, the catchment area can be seen as a boundary that determines the reach and influence of the institution, as well as the demographics and characteristics of the individuals it serves. The concept of a catchment area is crucial in urban planning, resource management, and service provision, as it helps to identify and understand the interconnectedness and interdependence of different communities and ecosystems within a larger geographical context.
