| description |
The study has conducted on a part of the Great River between (Rezan and its mouth) with the aim of determining the effect of geological factors on the stream of the Great River, based on the indicators and equations of morphometry such as identifying areas that have been affected by tectonic activity to some extent on the river stream, by using the (SL Index) on the parts of the river stream based on the determination of elevation points through Digital Elevation Model data (Dem 12.5m) by selecting (29 elevation points) on the entire stream. Then determine the length of each part based on the (Arc map 10.0) program. At the same time, using indicators of the relative relationship between the width of the river valley base to the height (Vf) and the value of symmetry and asymmetry of the river bends in the area.
In this study, the value of SL in the study area ranged from (0.8) to (44.1) out of (28) streams, while the number of points with values greater than (2) reached (26) points, which among them 12 points are more than (10), which mean their values range from (11.8 – 44.1). In terms of the appearance of the river valley, the results of the indicator (Vf) show that the study area from the beginning to the (Bekhma) port, its shape of the river valley is close to the English letter (V). After the (Bekhma) port to the mouth of the river, the shape of the river valley is close to the English letter (U). In terms of the value of symmetry and asymmetry of the river bends in the area out of the total (4) taken bends, it has appeared that the bend of (Gardmamk) on both sides (X and Y) are asymmetry, and also (X) from bend of (Goska) and (Y) in (Sheikh Saran) bend are asymmetry.
