COMPARISSON OF THE RESISTIVITY ANISOTROPY OF THE FRACTURE BED-ROCK IN AREAS NEAR TO DIFFERENT TYPES OF STUCTURES AND HIDROGEOLOGY IMPLICATIONS FOR AN RURAL AREA AT LOS SANTOS, SANTANDER, COLOMBIA

Groundwater represents the largest volume of drinking water in the world, so its study is essential to understand its cycle. One of the geophysical methods most used to determine some of the characteristics of the reservoirs of subsoil waters is the geoelectricity. With this method it is possible to obtain resistivity measurements, a very useful physical property for the discrimination of water saturated areas. This property, which varies according to the type of rock, the percentage of saturation and the salinity of the water, will also be affected by the fracture density. The present document corresponds to the proposal work for a master in Geophysics degree, whose general objective is to compare the anisotropy of the resistivity of the fractured subsoil to determine its hydrogeological implications in the Upper and Lower members of the Los Santos Formation an area of the municipality of Los Santos, Santander. The obtained geophysical information and its integrated interpretation with geological criteria will increase the potential knowledge of water and will constitute a contribution of quality information with a social impact in the study area.
