- This research is to identify the underground river flow patterns, namelyLuweng Sapen in the Mudal, Gebangharjo, Pracimantoro, with geoelectric methods Wenner-Schlumbeger configuration. The measurement were performed by using a resistivitymeter OYO type 2119C McOHM-ELwith a line length of 480 meters and 800 meters, the distance between the potential electrode are 30 meters and 50 meters, and the current electrode multiplier factors (n) are 1,2,3,4,5, and 6. The dataprocessing usedRes2dinv software version 3.56.After data processing, it can be said that the resulthas a tendency to form a contour hallway pattern in the range of resistivity 69.2 to 1110 Ωm. Line 1,2,3,4have a contour pattern resembling the hallway the alleged as underground river. Layers of carbonate rock that form the hallway is alleged to have the capsrock and water pocket of the structure of underground river. The hallways of the layer of carbonate rocks on the line isalleged to have the properties of the water carrier which is the path of an underground river Luweng Sapen. The pattern of underground river flow of Luweng Sapen alleged heading toward to the Southand branched into two hallways. The first branch, heading towards to the East of the line 4 and second branch alleged toward to the South heading the line 2 and 3. Keywords: carbonate, underground river, geoelectric, resistivity
