Derivation :

Following assumptions are made :

  1. Bed slope is small.

  2. Channel is rectangular and straight.

  3. Flow is steady and streamline are approximately parallel.

  4. Roughness is constant

Notations :

enter image description here

$\delta l$ = Length of channel of rectangular cross section

S = Bed slope

D = Depth at section A

$\bar …
