Andras Bardossy Karlsruhe, 2004 ii Acknowledgement Only the timely support of Prof. Dr.-Ing., Dr. h.c. mult. Franz Nestmann has enabled me to successfully perform this research work at Institute for Water Resources Management, Hydraulics and Rural Engineering (IWK). He has co-operated and motivated me during difficult moments and provided financial support in spite of no external research funding. My thanks are due to Prof. Dr. rer. nat., Dr.-Ing. Andras Bardossy for his invaluable comments, in-depth understanding and moral support in improving several loosely written parts of this research work. His supervision strengthened my confidence and professional abilities. Over the last 2-years the entire hydrology group at IWK provided a warm and friendly working atmosphere, be it exchange of professional ideas or introduction to new scientific tools. Dr.-Ing. Jurgen Ihringer and my colleagues Marcus Casper, Dr. Charlotte Kämpf, Falk Lindenmaier, Martin Helms, Wolfram Schädel, Rolf Becker, Jutta Szabadics, Oleg Evdakov, Andrea Blatter, Joachim Liebert, Bruno Buechle, and Patric Preuss for their day-to-day help related to Geographical Information System (GIS), hydrologic modelling, remote sensing and database management. Mrs. Kay Dietner took the responsibility of correcting my Indian English and Resources Engineering office including its current and former staff for their all time help for daily life. Besides the professional skills, I am grateful to all of them for the common time in which they introduced me with the fascinating nature and culture of German folks and particularly of the Baden and Black Forest region. Although this was a wondrous and lengthy journey, but will be fondly remembered in years to come. I am very much thankful to Dr.-Ing. Erwin Zehe, Junior Professor at University of Potsdam (formerly at Institute of Hydraulics Engineering at University of Stuttgart) and Dr. Jens Lange, Institute of Hydrology, Albert-Ludwigs University of Freiburg im. Brs. for sharing the responsibility of translating my research vision through their professional support in explaining the complex models, model parameters and structures during our several untiring meetings in Stuttgart and Freiburg during 2002 and 2003 without asking any service in return. Also thanks for Dr. Thea Vogt from University of Strasbourg, France for introducing me the basics of remote sensing and the art of digital image classification. iii My special thanks to Mr. Salilendra K. Shrivastav and Mr. A.N. Borbankar from State Water Data Centre, Water Resources Department at Bhopal for their efforts in organising the rainfall and discharge data and their encouragement for initiating water resources research in this virgin Anas catchment. Ms. Meera Shahi and Mr. P.S. Sodhi both from Gramin Vikas Trust Jhabua believed in my concept and established a pilot hydrological measurement station in Kanjawani mili-watershed since June 2002. Also due thanks to Prof. Dr. Eldho T. Iype from Civil Engineering Department at Indian Institute of Technology (IIT) Bombay for supporting my research ideas and exposing them to the larger research community in India. Our research co- operation has been recognised as we won the best poster award from Stockholm International Water Institute (SIWI) during 2002 World Water Week in Sweden. Thanks to Mr. Wasim Akhtar former District Collector of Jhabua for providing much needed logistics during two field visits. I am thankful to Ministry of Science, Research and Culture (MWK) Baden-Würtemburg for sponsoring my most of the stay in Karlsruhe, German Academic Exchange Service (DAAD) for sponsoring few field visits to India and Karlsruher Hochschulvereinigung (KHV) for partial financial assistance for buying digital satellite data of Landsat TM from United States Geological Survey (USGS). Last but foremost appreciation to my wife Rachna Gangwar for her constant support, lot of sympathy and financial backing in completing this research work. Finally, this work is dedicated to late my father and teacher (1936-2003) who always dreamed best in me for improving the miserable life of rural folks in India. Anupam K.
