Open-Channel Flow

Spring 2015
T. K. Gates, Instructor

"Flow conditions in open channels are complicated by the fact that the position of the free surface is likely to change with respect to time and space and also by the fact that the depth of flow, the discharge, and the slopes of the channel bottom and of the free surface are interdependent."
Ven Te Chow

"It is a capital mistake to theorize before one has data. Insensibly one begins to twist
facts to suit theories, instead of theories to suit facts.
