Solution of Open Channel Problems

Solutions to problems are achieved by a combination of

  • Fluid Mechanics: conservation of mass, momentum, and energy

  • Empirical and theoretical equations & nomographs (graphical calculators). These are espeically common in 1-D steady flow applications.

  • Computational hydraulics. Complex geometries, unsteady flow.

    1. 1-D steady/unsteady is routine

    2. 2-D steady/unsteady is state-of-practice

    3. 3-D steady is state-of-art

    4. 3-D unsteady is research (for now; but just wait a few years as technology advances)
