There are various methods used to determine water consumption in open channel flows.
For many reasons, such as environmental factors, natural conditions, and flow characteristics,
measurements in streams cannot be performed by field surveys. These difficulties have led
researchers to develop many empirical formulas. Manning's equation is the most famous and widely
used of these formulas because it is simple to use and often gives good results. In this article, the
method of calculating water consumption using the Manning equation was considered. A formula
used to find the average flow velocity in a riverbed or floodplain was published by Robert Manning
in 1889. The aim of the study is to determine Manning's coefficient (n) in both river area and marginal
areas using Cowan's method methods which include most parameters. It is for this and other reasons
that the President of the country, Mr. Ilham Aliyev, paid special attention to the efficient use of water
and signed several decrees, and the water strategy of the Republic of Azerbaijan until 2040 was
prepared. Accurate water reporting is recommended in this strategy.
