The Morphmetric analysis of one of desert vallies southern Al-Thirthar lake and its agricultural uses

Abstract

The Morph metric characteristics are one of the Quantitative Geomorphology characteristics in general. They are analytical tool dealing with land forms and depending on data collected from Topographic maps or other sources ,.to determine land use. One of the vallies at lies Southren al-Thirthar lake between .(33 40 ,33 30 N and43 13, 43 21 S) was chosen for this study .the area of study consists of tow parts. (an Eastern one known as; Abu-Sudeira vally and aWestern one known as ; Al-zqer vally). That they meet to form the main vally.Some Morph metric shape propertieswere studied (Form Factor ; Compactness Coefficient; Circularity Ratio;), and Relief characteristics (Relief Ratio , Ruggedness Value, Hypsometric Integral, Relative Relief,) also network characteristics were studied (Drainage Density, Stream Frequency, Sinuousity Index, Bifurcation Ratio,). using Topographic map of 1:100000 scale to provide a back up data base system may be used in the near future for agriculture purpose due to population growth and urbanization extension against a agricultural uses of lands . Results showed that the main vallies was more closed to the triangular shape for from the regular circular one ,and it is less reliefed Ratio,with low density due to Straheler,1952 classification, and it is still in the youth stage, and recent de composited and out complex land form.
