Preface
fering from conventional hydrological and water management data and models.
However, this structure provides new and unique information not generally available from conventional measurements and models.
Additionally, we observe a growing number of university departments, (e.g.
civil engineering, agricultural and geosciences) offering courses in remote sensing
theory and applications. This book should also be of value to students in these
fields because it provides an up-to-date compendium of the state of the science of
remote sensing applications in hydrology and water resources management.
In a time of impressive growth of knowledge in all fields of natural and technical sciences and of rapid changes in relevant technologies, the editors realized that
much of this information is scattered throughout many discipline oriented journals
and publications. Based on their own scientific work and their long-term international activities the editors realized that it would be beneficial to the hydrology
and water resources communities if this information could be pulled together under one cover. They carefully selected the 25 authors from many institutions in
nine different countries. Although the book covers almost 500 pages, it is by no
means comprehensive, a reason, why it is important to provide an extensive list of
references, altogether more than 700.
The editors wish to thank not only their authors, with whom they co-operated
for more than four years, but also Joachim Geyer, who assisted patently with the
compilation of the chapters and Springer-Verlag which organized the production
and publication of the book.
