Webnature. In fact, Gardner-Kawahara equation is a particular form of extended KdV equation. The equation can be widely encountered in shallow water waves having surface tension as well as in plasma physics. In terms of physical interpretation, the Gardner-Kawahara equation expalins the solitary wave propagation in media [9].In Webwaves can be modeled by specific (rational) solutions of the nonlinear Schrödinger equation. This equation is a generic model for wave propagation in dispersive media with weak nonlinearity. This thesis is devoted to investigation of rogue waves in various nonlinear systems, including water waves, plasma, and optical fibers.
