The water movement in the soil contributes to entrainment of particles of varying sizes, and over time, some tendency for the orientation of this flow may occur. In the areas with particular soil characteristics, an internal discrete drainage network appears, that manifests differently depending on the causative factors. The aim of the recording and monitoring of this concentrated water flow movement that contributes to soil erosion as a pipe network through a geophysical method is to understand its evolution. Using a method such as the Self Potential (SP) allows the study of the piping processes in a quantitative manner. In the peripheral area of the Dognecei Mountains, specifically near the Doclin village, it was analyzed one such area in which this process occurs.It was analyzed the evolution of a site in periods with different climatic parameters which are the ones that act as the active elements.The amplitude of the SP values (mV) differs based on the causative environmental factors, with negative values in the dry period and positive values when the soil is wet, the values having fluctuation up to 15 mV. The piping processes contribute to soil degradation and the knowledge of the areas affected by this processes and particularly of the factors influencing its occurrence can be achieved with good results by using the Self Potential method.
