Subject: watershed
Nid 'cefn deuddwr' na 'gwahanfa ddwr', ond
yr holl dir mae'r dwr oddi arno ac oddi tano yn draenio i afon neu lyn neu
gorff dwr arall.
Diffiniadau o'r We:
"The specific land area that drains water into a
river system or other body of water. "
"..all the land that serves as a drainage for a
specific stream or river. In urban watershed management, a watershed is seen
as all the land which contributes runoff to a particular water
body..."
A oes term
cydnabyddedig?
