Water requirement

What is Water requirement?

Water requirement meaning The divide separating one drainage basin from another and in the past has been generally used to convey this meaning. However, over the years, use of the term to signify drainage basin or catchment area has come to predominate, although drainage basin is preferred. Drainage divideor just divide, is used to denote the boundary between one drainage area and another. Used alone, the term “watershed” is ambiguous and should not be used unless the intended meaning is made clear.
