Abstract: We consider a number of examples where the NLS equation can be derived as an amplitude equation. We discuss the question: When makes the NLS approximation correct predictions and when not. Especially we consider the NLS approximation for the water wave problem. We explain how numerics has to be used to get some insight into the problem.
