In Physical Geography , a Water Catchment Area is a Drainage Basin or watershed, the region of land whose water drains past a specific point along a river or into a specified body of water. The determination the catchment area is important in the field of Water Supply and Hydrology . In Human Geography a catchment area is the area and population from which a city or individual service attracts visitors/customers. For example, a school catchment area is the geographic area from which students are eligible to attend a local School . A neighbourhood or district of a city often has several small convenience shops, each with a catchment area of several streets. There is a much lower density of supermarkets, and these have catchment areas of several neighbourhoods (or several villages in rural areas). This principle, similar to the Central Place Theory , makes catchment area an important area of study for geographers, economists and urban planners. |
