Generalized Water Surface Profile Computations
Publication: Journal of Hydraulic Engineering
Volume 111, Issue 3
Abstract
A computer model based on both the energy and momentum equations is developed. This generalized model can be used for the computation of water surface profiles through hydraulic jumps. It also allows computation of water surface profiles regardless of whether the bed slope is steep, mild, horizontal, adverse or a combination of these. The control section can be a lake, weir, gate or a natural river section. The Manning, Chezy or Darcy‐Weisbach equations, can be used for head loss computation. A detailed description of methods used and a step‐by‐step computation procedure is given. Examples are used to demonstrate the applications of this generalized model for water surface profile computations.
