Abstract:
According to human request for various uses of freshwater in the world, karstic area can be one of the places with sufficient water potentials. Therefore, detection of the fractured zones and faults can introduce places with suitable water potentials. Studying geological and geophysical together in karstic area can be vital since their sudden variation of resistivity may load to identify them. These changes are related to fractures, porosities and permeability... etc. In this work investigation of situation of alluvium and karstic in Amr – Abad region of arak has been carried out using geophysical data and resistivity as well as present information from drilling by modeling. In this project 39 vertical electrical sounding (VES) along 6 profiles were carried out with Schlumberger method. In this paper, interpretation is firstly carried out manually and then, one-dimensional modeling was employed by 1X1D software using the results of manual interpretations and geological controlling. To obtain general and qualitative information about underground conditions, the obtained data was entered to Res2Dinv software for two-dimensional inversion to investigate the underground geological situation. At the end, the interpretation results are used for determination of alluvium layers and estimation of bedrock depth in the studied region.
