A new model for propagation of nonlinear internal waves in coastal areas in considered. The model takes
account for an inhomogeneity such as a sloping bottom and for the losses such as the bottom friction in shallow
zones. The model is based on the Hamiltonian approach resulting in derivation of an evolution equation
applicable for strongly nonlinear waves, for which both the mass and energy are conserved (unlike the previous
evolution models for which only either of them were conserved). Processes of formation and destruction of
solitons and soliton groups (solibores) are considered. Whenever possible, comparisons with observational
data are presented.
