A Determination of an Abrupt Motion of the Sea Bottom by Using Snapshot Data of Water Waves
Comparison of the regularized wave spectrum with the exact one for four cases of regularization parameters ((a)–(d): noise level ). Legend: the dotted and solid lines stand for the exact wave spectrum in (6.2) and the (Tikhonov) regularized solution in (5.3), respectively.
(e) Residual (the norm of difference between the exact and regularized spectra divided by the norm of the exact)
