1. INTRODUCTIONObjectivesGain more insights on the age and genesis of the karez by finding the oldest karez system in the region. MethodInvestigating, inventorizing, measuring and mapping of different individual karez wells. Extraction of the exact geometry using Pleiiades-1 satelite imagery (0,50 m resolution).Application of the results→ Composition of a database, containing each karez system in theregion.→ Gaining more insights the age and genesis of the karezWorkflow1. Data acquisition: field work2. Data processing: mapping and creating a database3. Interpretation of the results3. DATA ACQUISITION: FIELD WORK6. CHALLENGES AND FUTURE RESEARCH5. RESULTS2. STUDY AREA4. DATA PROCESSING: MAPPING & DATABASINGOnly one active line in the three examined systems→ most systems are destroyed /ababonded / have disappeared→ depth deeper than 100 metresThe irrigation of the Valley of the Grapes is provided by water pumps and not by the use of karez.Relative chronology can be determined within lines of one system.One line in the Southern system is in the surrounding of a brick building of Nestorian age. This same line is in the middle of a Chinese burialplace.Recent human impact (building of a High Speed Railway) destroyed a whole series of karez in the Northern system.One karez line of the Northern system disappears into a gully of recent date.MappingInventorized parameters per individual wellData acquisition and processingDifficulties in exact planimetric and altimetric localisation of the karezmounds.Future researchSoil samples will be taken from both the active karez line and other lines (determined as ‘older’ by relative dating). Using an absolute dating, the oldest system in the region can be determined.North of the Flaming Mountains, there’s a bigger area with more karezsystems. Having obtained know-how on how to examine karezefficiently, this second complex can be the subject for a future research.Valley of the Grapes, 10 kilometres Northwest of TurpanArea of interest of  30km²7.
