Acknowledgment
The process to write such a text book is impossible without external help. First of all
I would like to say thank you to my family who has to cope many times when I hide
myself away to make progress. Furthermore, I am grateful to my colleagues Leo Adriaanse
and Helge Bormann who read first drafts of this book and provided me with helpful and
substantial advices. Last but not least, Helge Bormann took over to write the chapter of
coastal hydrology, thank you very much.
