LINEAR AND NONLINEAR MODELING OF LONG WAVES PROPAGATING AROUND CHANNEL BENDS

Aimin Shi, Michelle H. Teng

Abstract


In the present study, the transmission and reflection of long waves traveling through right-angled channel bends of constant depth and width are investigated by using numerical simulation based on the linear and nondispersive long wave equations. The present linear results are compared with the results obtained by Shi, Teng and Wu (1998) based on the weakly nonlinear and dispersive Boussinesq equations. The objective is to examine the difference between linear and nonlinear modeling of long waves propagating through curved channels.
