This literature contains of results of an engineering evaluation of the structural geology at Karun II dam site, especially at alignment KII A-3. Tear fault, weakened limestone and displaced rock mass are the important properties of this axis. It?s mentioned that because of complicated tectonic condition, this axis is exclusive, as after nearly 60 years from primary studies, there are so many problems about the aspect of this axis.
Many different phenomena affact near surface seismological parameters. One of the most important problems is the case of near surface anisotropy. Some of common examples of these zones are joints, cracks and preferred orientation of cracks and joints within a refractor. This study addresses a new kind of small scale near surface anisotropy. The results interpreted as 2 layers and the effect of water channel on the time-depth and depth contours analyzed. Final conclusion is a good estimation of both horizontal location and depth of water canal with respect to prior information.
