FEATURES OF IMPULSE WAVES Sample Clauses

FEATURES OF IMPULSE WAVES. Waves generated in bodies due to release three features (Fig.S.2): Wave generation due to impulse on water Wave propagation over the water surface, and Wave impact on water boiindaries, such as shores or man-made structures, including possible overtopping. The first wave the wave amplitude, and contains also the maximum Waves develop a highly complex phenomena close to impact location into a gradual surface is to computational analysis, Waves decay in they travel over a water body of nearly constant depth, Typical developed waves are either of solitary or cnoidal wave type, and Wave runup and wave overtopping depend on shore conditions and are governed by processes. Given the and abrupt temporal changes, both the impact an the runup I not to prediction, except for hydraulic modeling provided the proper are accounted for. Two cases have received particular attention in past, plane impulse wave and the spatial impulse wave. These are described below. The impulse wave was considered under the following conditions (Fig.6.3): (1) Relative wave smaller than wave breaking limit, a relative amplitude smaller than 78% of the still water depth, (2) Relative propagation domains larger than and smaller than around times the still water depth, (3) Slide velocity than half of wave celerity, (4) Slide angle larger than about and smaller than and (5) Dense slide such as for a rock avalanche but not for exploded material containing much dust. I into a) plan, b) section. The maximum wave amplitude relative to the still water depth depends on four dimensionless quantities, namely the slide angle y with a large effect, the relative slide volume with an effect, and the prodiict of density ratio times the relative distance a relatively small effect. The notation is explained in and and are densities of slide and water, respectively. For any given potential slide location, the slide density the slide angle y and the still water depth can hardiy be influenced. The only parameter with a degree of variability is the slide volume per unit width The still water depth can of course be reduced for slides that do not immediately occur, provided the water be drawn down by a at point P and propagating towards For a slide running into a reservoir resulting spatial impulse wave, the relative wave amplitude follows previous characteristics, except of lateral wave propagation and waves propagate radially from the impact location into the water body. The highest wave occurs in the direction of...
