From the reviews: "The book by I. Lavrenov presents his view on the subject, based upon more than 25 years experience both in fundamental theoretical and experimental research, as well as in developing operational forecasting. ... The book contains a lot of helpful material ... . The book has a consistent underlying philosophy, being 'practically' oriented ... . Scientists and engineers concerned with practical aspects of wave modelling could definitely benefit from having it as a complementary one on their shelf."
