The water-bearing structures are most favorable targets for finding underground water in karst regions. There are some kast springs, sinkholes of pearl-string shape on the boundary between soluble and non-soluble rocks which often indicate the existence of underground kastificaton developed intensively. The soluble rock zones along the boundary are good positions of detecting karst underground water. The hard and fragile rocks such as limestone and dolomite form tensile fractured zones is a good place of underground water storage. Faults and fractured zones not only make underground water link each other easily but also become the better water bearing carriers. In these areas, the parameters of extension direction, width and down-stretching depth of the water bearing structures can be gained rapidly.
