Hydrogeology is an interdisciplinary subject; it can be difficult to account fully for the biological, chemical, physical and even legal interactions between soil, water, nature and society. The study of the interaction between groundwater movement and geology can be quite complex. Groundwater does not always flow in the subsurface down-hill following the topography; groundwater follows pressure gradients (flow from high pressure gradient to low) often following fractures and conduits in circuitous paths. Taking into account the interplay of the different facets of a multi-component system often requires knowledge in several diverse fields at both the experimental and theoretical levels.

The hydrogeologist specializes in the search for underground water and in its exploitation whether for industrial or domestic  use. Apart from his geological knowledge, he must also be skilled in hydraulic. His services are required in finding and exploiting aquifer (water bearing strata), studying the quality of waters and conserving them.

In the third place, his research is on the plateau karst geomorphology units with a slope of rock layers that really horizontal (average <1^o). Although already believed that the influence of ground water is a major factor in karstification, but few realize Kastning findings Kastning (1984) of which is that the regional karst mountains forming the terrace morphology (Topographic benches). Formation other than as a result of the differences that make up the mountains litologi the plateau (horizontal layers), is also suspected to be due karstifikasi development. Other findings is that for certain muscular control structure is most apparent in the control configuration of the cave passages in the research.
Yet despite the heavy main controls, Kastning (1984) found that the fault does not always act as a weak zone that will trigger the development of rock permeability. In some places fault lines of little or no effect on the development of the cave. Even at the fault lines up, the rocks have recrystallized to form impermeable surface, causing hidrogeologinya conditions do not develop.
