DAMPING OF FINITE AMPLITUDE SOLITARY WAVES IN A FLUME

Solitary wave is a permanent when the dissipation ignored. Many analytical solutions have been developed for finite amplitude solitary waves. In additional to perturbation solutions, closed form are also available (e.g., McCowan 1891, Clamond and Fructus 2003, being denoted as CF from hereon), which more accuracy, especially larger waves were discussed in Wang Liu (2022). (2022) ’s laboratory experiments, slowly damped along flume, can be attributed energy inside boundary layers on bottom sidewalls. Keulegan (1948) first derived an approximate solution describe damping flume small wave. The basic idea of calculating effect that rate must same loss. this work, principle balance adopted flume. provided employed here analyses.
