hi everyone. heres the picture of the drain.

its part of a larger system known as the drainage system/basin.

this particular part is a channel and it will flow down till it meets a bigger channel and this channel will join with other channel and finally join with the main river. hence it can be considered as a tributary.

on another note, i would like to point out a difference in the 2 terms which some people use interchangeably but in technical sense is different. they are watershed and drainage basin/catchment area.

now in layman terms and in the U.S. these are used interchangeably, but just to be on the safe side, the drainage basin is the total area of land where water in that land will flow into a body of water (e.g a river) while a watershed is the divide that demarcates and distinguishes/separate one drainage basin from another.

anyways, have a nice long weekend peeps! p.s. we will miss chinese class on mondays for 2 weeks. hoooooorrrrraaaayyyy!

cheers

  1. I feel that overall that this entry is good. However i also feel that this entry is lacking the main points on how a drainage basin works and how water passes through it. Furthermore the difference between watershed and drainage basin is not very important as they are used interchangeably in Singapore and teacher understands what you are saying if you write any of these terms.

  2. I feel that more detailed explanation is needed on what a drainage basin is. And how it works to transport water.
