| Abstract | ||
| A seismic refraction investigation was carried out at Al-Aziziyah area for delineating water table and determining the velocity of different layers, as well as locating the contamination zones in under ground water which are resulted from agricultural activities. Nineteen seismic profiles were carried out in this study using ABEM TERRALOC seismic system. The length of each profile ranged from (33-115) m. with normal and reverse shooting. The recorded field data interpreted by delay time method using time distance curve as well as plus-minus method, mean-minus time method, ABC method and generalized reciprocal method. The velocities of the first layer range from (252-404) m/sec. and its average is (295.53) m/sec. while the velocities of the second layer ranges from (1335-1666) m/sec. and its average is (1494.21) m/sec. the velocities show no significant difference after interpreting by different methods. In this study the second layer represents the water table in the area with the depths range from (2.2- 5.5) m. Finally the contour map was drawn for the water table of the ground water, as well as a map differentiating the contaminated from non-contaminated zones. | ||
