Abstract The equilibrium condition between driving and retaining forces causes uniform flow. The conditions of uniform flow are discussed in detail first. Then, uniform flow is described with formulae and applied on the partially-filled circular, the egg-shaped and the horseshoe profiles. Approximate expressions are derived for discharge, flow depth, energy head and critical bottom slope allowing for a simple application of uniform flow. In addition, aspects such as air entrainment in steep sewers or choking of sewers from supercritical to pressurized flow are described. The design procedure is finally outlined and illustrated with examples.
