Abstract
The study area is located in the eastern part of the Diyala Governorate close to the Iraqi-Iranian border. This study was set to investigate the hydrogeological calculations of northeast of Qazaniyah wells where the groundwater moves in directions of from the northeastern parts towards the southwestern par, that is, the same direction of the topography and the same direction of the tendency of the layers t. The study‘s region is characterized by visible geological layers or those that can be penetrated to a reasonable depth by wells which are sedimentary rocks deposited in continental or semi-continental conditions in the bays. From the study of the hydraulic properties of the two hydrogeological and exemplary systems, the values of transmissivity, permeability and storage coefficient are ranged between 1.94- 5.73 m2/day, 1.02- 3.92 m/day and1.40 x 10-5- 2.62 x 10-4, respectively. While the estimated value of transmissivities, which are obtained from specific capacity, ranged between 6.27- 8.62 m2/day. This variance in the values indicates the broad differences in the values Lithology of aquifers, which seems to be influenced by the strength and the number of fractures and joints.
Highlights
The study area is located in the eastern part of the Diyala Governorate at the Iraqi- Iranian border by latitudes 33 ° 0 ', 0" and 33 ° 20' 0", and longitudes 45 °3'0", 45 °24' 0", 45°45' 0" and 46°6'0"E (Figure-1)
The study area has no surface water to recharge the groundwater, so the groundwater is fed by rain water
The flow network consists of two sets of lines: The first group is called isoelectric lines that connect water points at the same height above sea level, and it was calculated by subtracting the height of wells from the depth of water level in wells, and the second set is called flow lines which determine the direction of groundwater flow, Figure 4 shows the flow direction map of study area
Summary
The study area is located in the eastern part of the Diyala Governorate at the Iraqi- Iranian border by latitudes 33 ° 0 ', 0" and 33 ° 20' 0", and longitudes 45 °3'0" , 45 °24' 0" , 45°45' 0" and 46°6'0"E (Figure-1). The study area covers the Quaternary sediments, and the Tertiary sediments that appear along the edge of the Hamrin mountain range. The study area is located within the central eastern part of the Mesopotamian plain and at the southwestern part of the feet of the mountains 1 ,( Figure -2). These two regions represent the outer and middle part of the unstable range of the Nubio-
