Initiallythe water moves down the slope in the form of rillsor streams. In due course of time, a number of smallstreams, called tributaries, join the main stream.The main stream, with all its tributaries, developsa drainage system. The total area occupied by adrainage system is known as the drainage basin.• The higher ground, which separates the twodrainage basins, is called the watershed or thewater-divide.Originally, when the streams flow in the directionof the slope of the land, they are called the consequentstreams. As soon as such a stream is joined by atributary, that tributary is called the subsequentstream.The drainage pattern means thespecial arrangement of streams in aIt is thepatternTrellis DThe ttandt​
