Hot dam! ๐Ÿ”ฅ๐ŸŒŠโš ๏ธ

Know your watersheds.

 

Watersheds highly determine the volume and quality of water in water bodies where we get our supply of freshwater, while dams have been proven to be significant in ensuring the health of watersheds. Yet, dams are sometimes criticised for their detrimental impacts to downstream water bodies. So, what is a watershed? And what exactly are the effects of dams on watersheds?

What Is A Watershed?

A watershed is an area of land that channels water such as rain and snow to a body of water like a lake, river, or stream. This term is often used interchangeably with a catchment area, which indicates the area that carries water to a single examined point. To put it simply, a watershed represents the transitional area that carries water to its โ€œfinalโ€ destination while a catchment area varies whenever the examined point is changed. As everything flows from a higher to a lower region due to gravity, a watershed is always located higher than its โ€œfinalโ€ destination. Everything can be part of a watershed. Soil is evidently part of it, as water infiltrates into the soil or runs off on top of it and ends up in a body of water. Man-made infrastructures such as canals and even the surfaces of buildings, that serve as transitional areas between precipitation and the โ€œfinalโ€ destination, are also considered to be part of a watershed.
