The volume editor would be happy to receive any comments to improve future
editions. Comments, feedback, suggestions for improvement, or new chapters for
next editions are welcomed and should be sent directly to the volume editors. The
emails of the editors can be found inside the books at the footnote of their chapters.
The book is especially devoted to university Prof. Gheorghe Romanescu, editor
of this book, an eminent teacher and researcher in field of water geography, who
unexpectedly has left us on October 3, 2018, during the processing of this volume.
We appreciate his great effort in invitation of the authors because without his
contribution and hard work, the book would not arouse.
We would close the preface by the statement of Heraclitus “No man ever steps in
the same river twice, for it is not the same river and he is not the same man.” and
statement of Cehov “Everything must be beautiful in man, from the face to the
clothing, from the soul to the thought.”
