Discussion of “Evolutionary Algorithms for the Determination of Critical Depths in Conduits” by A. Kanani, M. Bakhtiari, S. M. Borghei, and D.-S. Jeng.

A discussion on the article "Evolutionary Algorithms for the Determination of Critical Depths in Conduits," by A. Kanan and colleagues, published in the November/December 2008 issue, is presented. The article utilized evolutionary algorithms to identify the critical depth of an open channel section. A definition of evolutionary algorithms is presented. The author argues the use of genetic algorithms to minimize the error function.
