The influence of geological structure on the endokarst and on the exokarst can be studied through the relationship between the discontinuities (faults, joints, fractures and foliations) and the speleological study of the underground caves. The present thesis, proposes a methodology that can be applied to all those geological areas where these types of formations are present. The study area that has been taken into consideration is the karst of the Sierra de las Nieves park, in the province of Malaga (Spain), an example of high relief karst, the biggest in the south of the Iberian Peninsula. The main objective of this work is the implementation of a 3D fracture model, with the support of the FracMan software, which can allow to characterize, determine, and quantify the conditions that cause the field of paleoefforts and current efforts in the development of the karst.
