Résumé
This study contributes to the analysis of water supply problems in arid zones. The main part of this study is about qanat system (karez), a hydraulic engineering system for taping underground water sources and as a basis of traditional land use in many arid areas of the earth, with particular emphasis on its origin in Iran. Mountains surround many arid regions of the earth. Climatically they form a contrast to the adjacent steppes and deserts. A large part of the precipitations in the mountains seeps into the rubble trains. In ancient times, man has learned to utilize this source of water using a brilliant method called qanat (karez). The Persians developed qanats already thousands of years ago. The technology of qanats has spread from Iran to almost all arid zones of the world. In many countries of arid regions like Iran, the qanats are still in use and playing an important role for water supply. The importance of the qanat system is also due to the high quality of irrigation water as well as its low salt content. It is also desirable to tap water in basins or dams during winter time. The increase of the well drillings will lead very quickly to an exhaustion of the available ground water resources while water consumption permanently increases in populated areas, causing serious problems for water supply and environmental problems in all arid areas of the world and can become a source of conflict. A sufficient water supply in arid zones could be achieved by measures that are based on a combination of proven traditional methods and modern, environmentally-adapted technology.
