Supports exact and approximate least-squares optimisation methodsSupports smooth and sharp constrasts inversionsSupports up to 16000 electrodes and 21000 data points on computers with 1GB RAMSeamless inversion of very long survey lines using sparse inversion techniques(RES2DINV only license includes limited used of RES3DINV 3D inversion program)Two-dimensional (2D) electrical imaging surveys are now widely used to map areas of moderately complex geology where conventional 1D resistivity sounding and profiling techniques are inadequate. The results from such surveys are usually plotted in the form of a pseudosection (Figure 1a) which gives an approximate but distorted picture of the subsurface geology.The RES2DINV program uses the smoothness-constrained least-squares method inversion technique to produce a 2D model of the subsurface from the apparent resistivity data alone. It is completely automatic and the user does not even have to supply a starting model.

To investigate this problem, a geoelectrical survey was conducted combining dipole-dipole and schlumberger arrays. At the beginning of the survey, schlumberger array profile carried out along the road.Supports the Wenner (alpha,beta,gamma), Wenner-Schlumberger, pole-pole, pole-dipole, inline dipole-dipole, equatorial dipole-dipole, gradient and non-conventional arrays.RES2DINV software For Windows 98/Me/2000/NT/XP. Supports on land, underwater and cross-borehole surveys Supports the Wenner (alpha,beta,gamma), Wenner-Schlumberger, pole-pole, pole-dipole, inline dipole-dipole, equatorial dipole-dipole, gradient and non-conventional arrays. IPI2WIN to determine the types and depths of subsurface layers and geoelectrical tomography of subsurface was done by RES2DINV. In order to provide an appropriate image of underground the electrical resistivity tomography maps (ERT) were prepared. A 2D forward modeling code for DC resistivity is developed based on the integral equation (IE) method.In the tomography sections, the investigation depth over.

Here, a linear relation between model parameters and apparent resistivity values is proposed, although the resistivity modeling is generally a nonlinear problem. Two synthetic cases are considered for the numerical calculations and the results derived from IE code are compared with the.
