| Abstract: | The propagation of long-waves, such as tidal waves from the coastal ocean into shallow estuarine waters, often produces asymmetries
of velocity and water level in time series resulting in long-wave breaking. Tian (1994) studied the mechanism of long-wave
breaking in an infinite channel with constant depth, consideringnth power bottom friction. This study is for the case of a half infinite channel with bottom slope, taking linear bottom friction
into account. The wave breaking time and wave breaking location are estimated and the criteria for long-wave breaking in this
particular case are obtained. The results obtained can also be easily applied to the case considering wind stress. |
