Morphometric analysis using remote sensing and GIS in the northern part of Western desert, Iraq

الملخص EN

GIS and image processing a great tools for identification of morphometric parameters such as stream length (Lu), stream number (Nu), stream order (Su), bifurcation ratio (Rb), drainage density (Dd), hypsometric integral (Hi), Hypsometric Curve, elongation ratio (Re), circularity ratio (Rc), and form factor ratio (Rf) The Morphometric based GIS was used to analysis a in Northern part of western desert, Iraq the result revealed that, Six Stream order identify in study area with Stream length (Lu) Km and Stream number (Nu) was: 1st order 1670.889 -642, 2nd order -744.559 -166, 3rd order -429.152- 37, 4th order- 302.677- 8, 5th order- 33.795- 2, and 6th order-58.526-1.

Bifurcation ratio (Rb) to all stream orders (first to sixth Order) vary between (2- 4.84) with average value 3.79.

Form factor is 0.107.

Drainage density ranged from 0-4.3 Km/Km².

The calculated value for the hypsometric integral (Hi) = 0.45.

The elongation ratio of study area is (0.24).

The circularity ratio value of the basin is 0.104.

Which refers elongated basin in shape with low active tectonic characterizing a mature drainage basin.
