The study of sea waves has always been in the focus of mankind's attention. This is attributed not only to a desire to understand the behaviour in seas and oceans, but also, it has some practical necessity. Developing up-todate wind wave numerical methods reguires detailed mathematical modelling, starting with wave generation, development, propagation and transformation on the surface in differ…
In the eight years sine the publication of the first edition, there has been tremendous increase in the use of mathematical models in environmental engineering, especially for the control of pollution in rivers and estuaries. Modelling has also addressed a much wider range of pollutants and there has been an increase in the range of conceptual approaches to the formulation of models. The text o…
