Water is vital for the life and health of people and ecosystems, and is a basic condition for the development of countries. Water resources, and the related ecosystems which are sustained by water, are under threat from pollution, unsustainable use, land-use changes, climate changes and many other forces. This book incorporates basic and advanced information on all topics and issues relevant to the preservation of water resources quality. Its mains strength lies in covering all aspects of water quality preservation, including: engineering hydrology, environmental and chemical aspects, quantitative (modeling approaches) and qualitative issues.

This book bridges the gap between the various disciplines dealing with the preservation of our future water resources - the main issue for the developing world

This monograph results from the 4th International Austrian-Israeli Technion Symposium cum Industrial Forum under the banner of the Austrian Technion Society initiative Technology for Peace - Science for Mankind, which was held in Vienna, 23 - 25 April 200 I, devoted to Preservation of the Quality of our Water Resources. The Symposium was a cooperative effort with the Austrian Federal Ministry of Education and Science and Culture, and the Austrian Federal Ministry of Economy and Labor. The program was structured and managed by a joint Program Committee incorporating the editors of this monograph, who are faculty members from the Stephan and Nancy Grand Water Research Institute at the Technion - Israel Institute of Technology, and the University of Agricultural Sciences (Bodenkultur) of Vienna. The Symposium attracted participation from universities, research institutes, industries, and national authorities from Austria, Germany, Greece, Hungary, Israel, Jordan, Palestinian Autonomy, Poland, Russia, Spain, Turkey, USA, and Uzbekistan. The Symposium topics were of major international interest, and talks were at a high professional level. Therefore, I have gladly accepted the initiative of the Symposium Program Committee to extend and expand manuscripts of special merit to chapters of this monograph, whose title is identical to that of the Symposium. Out of the 39 papers presented at the Symposium, 24 papers were selected for inclusion in this monograph, according to their scientific merit and quality of contribution to the overall subject. Those selected were expanded and subjected to peer review for inclusion in this Volume.
