2010Acknowledgement
During this thesis period, I became very interested into research in water re-
sources sector, especially hydrological cycle in central Asia. The key person for this
is my supervisor Prof. Dr. Andasr B ardossy who delivered me very much valu-
able ideas in this eld. His guidance throughout my PhD work at the University
of Stuttgart brought me to the stage where I can independently put e ort for the
development of research activities in water resources in central Asia. For this reason
I am pleased to express my deep appreciations to Prof. B ardossy for his precious
guidence. Moreover, I am very thankful to Prof. Dr. Bruno Merz from German
Research Center for Geosciences for his readiness to co-supervise this work. I also
appreciate his patience for the completion of this research at the last months that
overlapped with simultaneous activities of the project I was involved.
Many thanks go to Dr. Ing. Jens Gotzinger who helped me from the beginning
when I carried out my master’s thesis at the Institute of Hydrology and Geohydrol-
ogy. His highly appreciable helps whenever I needed them made my work easier at
that time. There are too many others whom I would mention in the rst page of my
work, but a page will not be enough for that. Mentioning few of many, I would like
to thank all my colleagues from the Department of Hydrology and Geohydrology of
Institute of Hydraulic Engineering. Namely, Arne Farb er, Wei Yang, Jurgen Brom-
mund, Christian Ebert, Jan Bliefernicht, Pawan Thapa, Jing Li, Schailesh Singh,
Min Liu, Henry Kindt, Henning Lebrenz and others. They have supported me when-
ever I needed it. Additionally, I would like to thank the new colleagues from the
Department of Hydrology at the GFZ German Research Center for Geosciences in
Potsdam for supporting me to complete my dissertation. My special thanks go to Dr.
Jusipbek Kazbekov from International Water Management Institute in Tashkent for
his support in data delivery. I also thank Luzi Bernhard from Swiss Federal Research
Institute for delivering data.
This page will not be complete if I miss my beloved family. My father and
mother, Asror Gafurov and Risolat Qoshanova, my brother Zafar Gafurov and my
sisters Mohira Nosirova and Na sa Bozorova have supported me mentally though
they were far away from me. This work would be impossible without the great
support of my wife Feruza Gafurova who took care of me and our beloved son Ibrohim
during the past di cult time.
Moreover, I would like to thank IPSWaT Program of BMBF for providing
me stipend for this research. My special thanks go to Ms. Gabriele Hartmann who
guided me with o cial instructions for completion of this dissertation. Finally, I
thank Bjorn Guse at GFZ for his enormous help on proofreading during the nal
step of my dissertation.
