There is much more here than a summary of the nature and distribution of qanats, and a more extensive journey through the philosophy, methods, tools, and terminology of qanat design and digging than previously assembled. Where does one begin to dig to ensure that the qanat tunnel will flow with water? How are practical considerations of landscape factored into the design? How are water quality and discharge measured? How does excavation proceed through bedrock and unconsolidated soil and how is this knowledge of geology and pedology acquired? How are vertical wells and tunnels excavated to maintain proper air supply, light, and water flow? How does one deal with special problems like tunnel collapse, the accumulation of gasses and vapors, and the pooling of water during construction? How are tools and gauges designed, maintained, and used? How have qanats been incorporated into other structures like watermills, reservoirs, ice houses, and irrigation networks? And how are qanats cleaned, extended, maintained through the ages, and incorporated into modern water supplies? The great contribution of this work is the story it tells of the ingenuity and practical skills of the qanat masters who for centuries and generations have cut an uncountable number of tunnels through bedrock and alluvium using hand tools and homespun solutions to problems that would vex the most experienced university-trained engineers. . 606 $aWater$xPollution 606 $aWater-supply 606 $aTechnology?History 606 $aCultural property 606 $aEthnology 606 $aCivil engineering 606 $aWaste Water Technology / Water Pollution Control / Water Management / Aquatic Pollution$3https://scigraph.springernature.com/ontologies/product-market-codes/U35040 606 $aWater Industry/Water Technologies$3https://scigraph.springernature.com/ontologies/product-market-codes/214000 606 $aHistory of Technology$3https://scigraph.springernature.com/ontologies/product-market-codes/T29000 606 $aCultural Heritage$3https://scigraph.springernature.com/ontologies/product-market-codes/419000 606 $aEthnology$3https://scigraph.springernature.com/ontologies/product-market-codes/X12070 606 $aCivil Engineering$3https://scigraph.springernature.com/ontologies/product-market-codes/T23004 615 0$aWater$xPollution. 615 0$aWater-supply. 615 0$aTechnology?History. 615 0$aCultural property. 615 0$aEthnology. 615 0$aCivil engineering. 615 14$aWaste Water Technology / Water Pollution Control / Water Management / Aquatic Pollution. 615 24$aWater Industry/Water Technologies. 615 24$aHistory of Technology. 615 24$aCultural Heritage. 615 24$aEthnology. 615 24$aCivil Engineering. 676 $a363.7394 676 $a363.73946 700 $aSemsar Yazdi$b Ali Asghar$4aut$4http://id.loc.gov/vocabulary/relators/aut$01063127 702 $aLabbaf Khaneiki$b Majid$4aut$4http://id.loc.gov/vocabulary/relators/aut 906 $aBOOK 912 $a9910155550803321 996 $aQanat Knowledge$92530681 997 $aUNINA
