The role of bottom friction in the runup of nonbreaking long waves on the shore is analyzed. The case of the normal incidence of monochromatic waves is considered. The relief of the model region consists of an even horizontal bottom area conjugated with a flat slope. The energy dissipation is estimated as the work of bottom friction forces over the wave field obtained using the known analytical solution based on the Carrier-Greenspan transforms. Estimates of energy losses for waves whose periods are typical for tsunami waves have been obtained. The energy dissipation is shown to be not concentrated in the shore line area as a rule. The question about the practicability of using partially reflecting boundary conditions on the coast to take into account the bottom friction in large-scale models of tsunami propagation is considered. 相似文献

Abstract Under a joint government/industry program called the Winter Ice Experiment Beaufort Sea (WIEBS), during November and December 1979 and April 1981, two data sets were acquired in the southeastern Beaufort Sea, for the purpose of developing and testing a dynamical/thermodynamical sea ice model. The data sets included meteorological, oceanographic, and sea ice parameters. Also, on a limited scale, ground truthing data were obtained. This paper deals with the data collection aspects of the experiment and their archival. 相似文献
