عنوان مقاله [English]
To study the important morphometric characteristics in hydrological studies The significant development of remote sensing and GIS techniques has helped to change the definition of surface drainage networks that were manually carried out on the basis of field surveys towards computerized computerization to extract and identify water drainage networks in terms of direction and basin pattern from satellite image data.
In this study, advanced means were used in remote sensing techniques (Digital Elevation Models DEM) computed from modern satellite images of the studied area as raw data and Arc GIS 10.4 as a program for measuring spatial and geographical analysis.The hydrogeological study indicated that there are five underground basin: the modern sedimentation basin, the Injana basin, the Fattah basin, the Euphrates basin and the Umm Al-Raduma basin. There are also basins within the water formation in Injana and the Euphrates. The basin area and circumference were measured using the GIS Arc View geographic information system. The area of the basin was (166) square kilometers, and the circumference of the basin was (244) kilometers.The soil permeability ratio of the main basin is high and rainfall is low. Therefore, the area is characterized by the presence of large and karst caves and cracks spread in the area, thus creating a good area for the process of filtering rainwater into the ground to feed the layers that have the ability to collect water, and form layers that contain groundwater.
It can be concluding the following points
After determining the basin on which the study was based, the water network was identified and its type (Dendritic Network), and the direction of water flow was determined from the higher
elevation areas right up the lower elevation areas
The underground water movement is characterized in a modern painting as being multi-directional, as it can be seen from the hydrogeological map. the direction of movement is towards the east and north-east due to the water divider. As for the southwestern part of the plate, the direction of movement is towards the south and southwest, i.e. towards Haditha Lake and the Euphrates River. As for the south of Haditha Lake, it is towards the northeast towards the Euphrates River. As for the middle of the plate in general, the movement of groundwater is towards the east, i.e. towards the Tharthar depression. And in the central southern part, the movement is towards the southwest, that is, towards the Euphrates River, due to the water divider.
