Water-bottom multiples represent a principal limitation of the application of single channel riverine seismic surveys. The high impedance contrast at the bottom and surface of the water column causes strong reverberations, which often mask the deeper reflections and make the interpretation difficult or impossible. This paper shortly addresses the advantages and problems of the different means of multiple suppression and suggests an alternative new solution applicable for the special case of single channel shallow water seismic profiling. The suggested method has been tested by finite difference modeling and a small-scale basin model.
