Abstract：The combined use of geophysical prospecting and hydrogeological analysis can help to improve the success rate of borehole siting in the karst area.The advantage of this method is elaborated in this paper with the case study of well ZK3 in Luojiaba,Qianjiang district.It is confirmed that groundwater occurrence in the karst area is dominated by geomorphology,topography,geological structure and lithology.The low lying syncline with specific lithologic configurations is the primary target area for borehole siting.Proper geophysi-cal techniques can be applied based on the geology and topography of the study area.The interpretation re-sult of audio magnetotelluric method can be reliable when the study area is characterized with the following conditions,such as partially covered,deep groundwater and the presence of large variety in electrical resistiv-ity between stratums.
