13. Introduction to Open Channel Flow and Uniform Flow

The chapter elaborates on the fundamentals of open channel flow, defining it as the flow of fluid in a partially filled channel exposed to atmospheric pressure. It discusses classifications based on time, space, Reynolds number, and Froude number, highlighting important characteristics such as free surface distortions that create waves. Additionally, the text introduces surface solitary waves and their generation in open channels.
