Stabilization of uni-directional water wave trains over an uneven bottom
Stabilization of uni-directional water wave trains over an uneven bottom
We study the evolution of nonlinear surface gravity water-wave packets developing from modulational instability over an uneven bottom. A nonlinear Schr\"odinger equation (NLSE) with coefficients varying in space along propagation is used as a reference model. Based on a low-dimensional approximation obtained by considering only three complex harmonic modes, we …
