%X In practice, the bottom pressure caused by seawaves (as well as the inverse problem of reconstructionof the sea wave field according to the indications ofbottom transducers) is calculated within the framework of linear theory. According to this theory, it iseasy to find the one point relation between the sea level oscillations and the bottom pressure variationsusing the spectral approach [1–4]. As a result, the bottom pressure becomes completely determined for theknown characteristics of sea waves. However, if lineartheory intuitively works well in the case of small amplitude water waves, one should not rely on linear theory,when a rough sea acquires an irregular and nonlinearcharacter as, for example, in the case of a storm at sea.For example, it is shown in [1] that the results of predictions of linear theory in solving the inverse problemdiffer by 15–20% from those measured under laboratory conditions and this difference is related to thenonlinearity and noise in devices.
