T1 EXPERIMENTAL AND THEORETICAL STUDY ON FLOOD BORE PROPAGATION AND MUSHROOM JET GENERATION OF DAM-BREAK FLOW JF Visualization of Mechanical Processes: An International Online Journal JO VMP YR 2011 FD 2012-05-05 VO 1 IS 3 OP K1 mushroom jet K1 dam-break flow K1 Benney shallow water equations AB Researchers are interested in studying dam-break flow and sedimentation not only because of the practical importance in civil and hydraulic engineering, but also because it is fundamental in fluid mechanics. Meanwhile, because of the damage to property, assets, and the loss of numerous lives, it is extremely important to have a good understanding of the landslide dam-break flow and sedimentation. The major objective of this study is to examine the detailed mechanisms of landslide dam-break flow from physical modeling. The experimental work is focused on the initial stages of dam-break wave-front propagation and mushroom jet generation during the flood bore propagation. Meanwhile, theoretical work of dam-break flow on a flat, horizontal beach is studied by using the Benney shallow water equations to catch mushroom jet generation of dam-break flow. The dam-breaking flow includes vortexes, vertical shear flow, and dissipation of momentum and energy on the front due to bore breaking. Propagating of hydrodynamics bores with breaking is analyzed by the mass, momentum, and energy relations on the shock wave. A nondissipative wave front propagates faster than classical bore, while taking into account how the dissipation and wave breaking leads to slowing of the wave front. An exhaustive comparison of experimental results with theoretical solutions is also made in this paper.
