摘要：
Interactions between two undular bores in a long rectangular channel are studied by solving the two-dimensional Laplace equation with fully nonlinear free-surface conditions. Each bore is generated by a steady bottom source or sink that is turned on impulsively. Two types of nonlinear interaction between bores are investigated: (1) The merging of two bores that move in the same direction. (2) The collision of two bores that move in opposite directions.
