ABSTRACT
Theoretical aspects of turbulent structures have been explored, using the statistical theory of turbulence for uniform and fully-developed flows in wide open channels. These are the simplest but the most fundamental flows that display two-dimensional (2-D) turbulent structures in open-channel flows. The scope of this treatment is like those for boundary-layer and closed-duct flows. The fundamental knowledge obtained from the study of such flows is important and useful, not only from the standpoint of understanding the concept of open-channel turbulence and its necessarily more complex flow structures, but also for developing numerical turbulence models of open-channel flows.
