Chapter 4 Open Channel Flows - Anasayfa
web.itu.edu.trChapter 4 Open Channel Flows 4.1. Introduction When the surface of flow is open to atmosphere, in other terms when there is only atmospheric pressure on the surface, the flow is named as open channel flow. The governing force for the open channel flow is the gravitational force component along the channel slope.
