Consider a uniform two-dimensional turbulent flow (in an open-channel): the local flow velocities are given by the following formula 1 In +Bs (1) V* K which is assumed to be valid up to the free surface (i.e., including z=h, where u = Umax). a) Bring Eq. (1) into the single term form 1 In A, ks (2) K b) What is the expression of A, ? What is the value of Aş for rough turbulent flow?
