Abstarct: Due to the importance and high quality of karstic waters in supplying water in our country especially in Shahrood city, it is attempted in this research work to recognize and explore karstic waters in southwest of Tepal area, Shahrood. For this purpose, integration of the results obtained from the methods of vertical electrical sounding (VES) and resistivity profiling has been used in this research work. The VES surveys have been carried out in 10 sounding points (S01-S10) using the Schlumberger array with electrode separations of a maximum 500 meters and also, the resistivity profiling surveys have been carried out along 4 lines (P01-P04) with a length of more than 4 kilometers using dipole-dipole electrode array with 75m electrode spacing and dipole steps 1 to 8 in the study area, and then, one-dimensional (1-D) modeling and interpretation of the sounding results using master curves and IX1D software, and two-dimensional (2-D) modeling and interpretation of the profiling results using Res2DINV have been made. Interpretation results show that; the location of S02, S03, S04, S05 and S08 sounding points and the parts of P01, P02 and P03 profiling line surveys could be expected as water bearing zone; and also results in both sounding and profiling survey methods are consistent closely. As a result of the interpretation and integration of the results, karstic water zones in the study area have been determined, and baxsed on that, suitable locations for drilling to access and extract karstic ground water have been introduced.
