Watershed & Watershed Delineation | Calculating Catchment Area

What is Watershed & Watershed Delineation ? A watershed is all the land & water which contributes runoff to a common point or outlet point. It is also called catchment or drainage area. The terms catchment & watershed are found to be used interchangeably. So, watershed area is the land area, from where all the surface runoff converges to a single point to give common discharge. Watershed delineation thus refers to creating boundary that represents the contributing area for a particular outlet point.
