ah i'm finally here heh

HI MY DEAREST CLASSMATES I HAVE SOMETHING AMAZING TO SHOW YOU GUYS.













*GASPS* OMG DON'T YOU FIND THIS FAMILIAR?!
okay yes it's found in nj of course. but isn't this amazing, i mean,
IT'S A DRAIN. :O

okay let me tell you more about this seemingly insignificant drain okay :)

This drain is part of a larger system, which is known as the drainage system/basin. Drainage systems are commonly found in urban areas, which includes Singapore. Drainage systems play an important role in preventing flooding and controlling water flow in different areas.

When precipitation occurs, interception of the water by the grass (vegetation) occurs, resulting in infiltration of water. However, some of these precipitation falls straight into the drains, which will then flow down till it reaches a bigger channel, where all the big channels will then combine to form the channel storage (river).

Precipitation can also reach the channel storage via throughflow, which means water moving through the soil, and overland flow, which refers to water over the surface of the ground.













Here's where the drain from the above diagram links to!

Hope this is useful in helping you understand the importance of drainage systems! :)

-Shumin!
