satellite images, satellite monitoring, transboundary river basin, water canal, technical characteristics of the water canalAbstract
Based on 32 images of LANDSAT-5, 7, 8 (resolution 30 m) during 1989…2017 years and 21 passing of QuickBird-2 (resolution 0,6 m) during 2003…2015 years, an inventory of the water canal: River Kara-Ertis – city Karamay, located in the Xinjiang Uygur autonomous rayon (XUAR) of the China, was made. The canal is used to transfer water from the trans-boundary Kara-Ertis River to the Dzungar Plain (the internal dry territory of the XUAR). The technical canal's characteristics: the gravity water canal, with 8 tunnel passages; the construction period is about 2 years (September 1997 – October 1999); the altitude difference is 270 m (from 632 to 362 meters above sea level [Baltic System]); length is 460,67 km; width are from 9 to 33 meters (depending on the slope steepness). The canal operates from April to October, the period of maximum load is June-July. The main task of the canal is to provide water to the arable lands of XUAR during the vegetation season.
