catchment
catchment The area from which a surface watercourse or a groundwater system derives its water. Catchments are separated by divides. A surface catchment area may overlie an aquifer system, but may be unconnected with the aquifer rock itself if there are intervening impermeable aquicludes. In US usage a catchment is often termed a ‘watershed’; in Britain the term ‘drainage basin’ is commonly used.
