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. 000778376 588__ $$aDescription based on print version record. 000778376 650_0 $$aQanats. 000778376 7001_ $$aLabbāf Khānīkī, Majīd,$$eauthor. 000778376 77608 $$iPrint version:$$aYazdi, Ali Asghar Semsar.$$tQanat knowledge.$$dDordrecht, Netherlands : Springer, 2017$$z9789402409550$$z9402409556$$w(OCoLC)953709460 000778376 852__ $$bebk 000778376 85640 $$3SpringerLink$$uhttps://univsouthin.idm.oclc.org/login?url=http://link.springer.com/10.1007/978-94-024-0957-4$$zOnline Access$$91397441.1 000778376 909CO $$ooai:library.usi.edu:778376$$pGLOBAL_SET 000778376 980__ $$aEBOOK 000778376 980__ $$aBIB 000778376 982__ $$aEbook 000778376 983__ $$aOnline 000778376 994__ $$a92$$bISE
