      The development of karst terrain and its water resources is controlled by many factors some of which are structural (such as faults, joints), lithological Formations and topographical parameters (slope and elevation). In the present study, the role of structural and topographical parameters controlling number of springs in Pabdeh- Lali anticline, NE of Khuzestan was evaluated. For this purpose, the techniques of remote sensing and GIS were used. The results indicate that the occurrence of springs is more in low slope areas (0-50), near to lineaments (0-200m) (fractures) with high density (15-25). In addition to these, the Formational permeability and elevation (confined to 600-800m) are other controlling factors.
