Abstract EN

The Quweiq basin is considered as the major basin in Aleppo plateau in the northweS of Syria, occupying an area of 5831 km2, of which 4930 km2 is in Syria and 901 km2 is in Turkey.

The study was carried out in 2014 in order to calculate the basin's morphometric properties using 18 topographic maps at scale 1:50000, and SRTM 90m-DEM to complete the basin's area in Turkey.

Data were processed using Arc Hydro which is an extension of ArcGIS.

The morphometric properties were calculated in a manual method (traditional) and in automated techniques.

The results showed variation between the two methods, as the Sream number in manual is 9102, in automated is 25922, total Sream length is 6949 km in manual, in automated 16884, mean bifurcation ratio in manual is 3.7, in automated is 4.4, Stream frequency in manual is 1.5, in automated is 4.4, Drainage density in manual is 1.2, in automated is 2.9, Sinuosity index in manual is 1.6, in automated is 1.6, ConSant of channel maintenance in manual is 0.8, in automated is 0.3.The Sudy showed that the using of automated technique is comprehensive, easier and fa^er than the manual method.
