Vertical-plane hydraulic problem

Figure 1.5 Schematic of the vertical-plane hydraulics problem.

This brief overview of the vertical-plane hydraulics problem may be accomplished with references to non-stationary problems. It is important for oceanography problems that the flow evolves in time because of the seagrass-current periodicity. In article [172], the one-dimensional problem (1.10) accounted also for the time- and space-periodicity of the sea water surface, g(x, t) = A sin(u>xx - oj,t). The final motion equation was written as... 

Active and vital biological life also occurs within aquatic vegetation. If this vegetation is deeply submerged in the water flow, it affects the flow in a similar manner to terrestrial canopies. Emergent riverine vegetation is also often met in practical hydraulics problems and may also be considered as a canopy , Chapter 6. Distributions of flow properties in vertical sections, the vertical-plane hydraulic problem, and the horizontal-plane hydraulic problem, Sections 1.2.1 and 1.2.2, distinguish between different aspects of the aquatic and terrestrial canopies. Chapter 6, however, shows a link between them.
