Abstract
Several factors are important to evaluate the potential of karst groundwater resources which can be referred to as hydrogeological (springs), structural (fractures and faults), geological (lithology), topographic (local base level and slope), precipitation and vegetation factors. The aim of this research is to assess the potential of karst groundwater in Dashtak anticline and its effective factors. Accordingly, several thematic maps have been prepared by means of using Geographic Information System (GIS) and Remote Sensing (RS) techniques. The rating has been done in each map by crisp method on a scale from 0 to 9. Weighting of the maps has been performed by using the analytical hierarchical process (paired comparisons), and finally maps have been combined using the index overlay. The final map includes weights from 0 to 9 and the classified map is presented. The results show that karst groundwater potential of the northern part of Dashtak is more than the southern part .The correlation between high groundwater potential areas and high discharge springs indicates that the proposed model can be successfully applied to karstic areas.
