Abstract: 

INTRODUCTION: BEDS OF MOST ESTUARIES AND COASTAL AREAS ARE COVERED WITH MUD OR SLUDGE OF SILT AND CLAY COMPOSITIONS. MUD EROSION DUE TO WAVES HAS RECENTLY RECEIVED PARTICULAR ATTENTION. RECENT STUDIES SHOW THAT THE SURFACE WAVE CAN EXCITE INTERFACIAL WAVES AT INTERFACE OF FRESH WATER AND FLUID MUD. THE AMPLITUDE OF THE INTERFACIAL WAVES GROWS EXPONENTIALLY INITIALLY AND REACHES A MAXIMUM BECAUSE OF NON-LINEAR RESONANT INTERACTION.
THE PREVIOUS STUDIES ANALYZED THE PROBLEM UP TO 2ND-ORDER, SO ONLY THE INITIAL EXPONENTIAL GROWTH WAS PREDICTED. PREDICTION OF THE ULTIMATE AMPLITUDE OF THE INTERFACIAL WAVES REQUIRES A HIGHER ORDER ANALYSIS.
