Horizontal-plane hydraulic problem

Figure 1.8 Schematic of the horizontal-plane hydraulics problem (A) plane view of the flow with vegetation near left bank (B) typical flow cross-section.

Theoretical approaches to the horizontal-plane hydraulic problem are often based upon momentum equations derived from the Navier—Stokes equations being averaged over the flow depth. This approach was developed by Rodi, Emtsev, Sherenkov, Beffa, and other authors [48, 171, 540], In the case where the vegetation is present, the resulting two-dimensional shallow-water equations for a time-dependent flow read as follows [540] ... 

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.
