5.6 Extended Motion Equation

The terms for the minor losses, together with the wind-stress terms added to equation 46, result in the extended-motion equation for curvilinear channels as

(64)

Equation

Some arguments for coefficients have been deleted to make the equation more compact. The value MT is a weight coefficient on the top width to give the correct water-surface area per unit length. It is related to volume per unit length just as the top width is to the area; that is,
