WebGradually Varied Flow - University of Memphis WebThe standard step method can be used to solve steady-state water surface profiles. The solution to gradually-varied flow profiles is based on the non-linear ordinary differential equation d y d x = S 0 − S f 1 − F r 2 and is appropriate for cases where d y d x is small.
