| Abstract | ||
| K-3 solution cavity is located within Haditha area, Western Iraq. The measurements of Graphical Bristow's method were carried out by using Pole-dipole array, to evaluate the method to detect the dimension of a relatively large natural cave. The cave resulted due to the dissolve of carbonate rocks within Euphrates Formation (Miocene). The actual depth and height of the cave are 38.8m and 29.5m respectively. Two traverses with a-spacing equal to (5m) and length of about 100m are achived, in South- North and West -Eest direction above the cave site. The data interpretation detect the cavity elongate along West -Eest traverse of 58.6m and indicate an error not exceeded 3% in depth and 2% in height values. The results are concluded that this method is useful to be able to detect subsurface cavities and voids. | ||
