Cnoidal waves are a type of wave solution that arises in the study of shallow water wave theory, particularly in the context of the Korteweg-de Vries (KdV) equation. They describe periodic waveforms that are more complex than simple sinusoidal waves or solitons, exhibiting an undulating shape that can have distinct crests and troughs.
