Get Res3dinv

A resistivity survey is a geophysical method used to map the electrical properties of the ground. This technique helps identify variations in soil and rock types, groundwater presence, and contamination levels. With tools like Res3dinv, you can streamline the data analysis process, ensuring you get the most accurate results for your project.

The four layer resistivity sounding curves represent different geological scenarios encountered during resistivity surveys. These curves help you understand how resistivity varies with depth and identify distinct layers within the subsurface. Using Res3dinv, you can easily model these curves and gain valuable information about the geological profile of your study area.

An ERT survey, or Electrical Resistivity Tomography survey, is a geophysical technique used to assess the subsurface properties of the earth. This method involves measuring the resistance of different soil and rock types to electrical currents, allowing for detailed mapping of underground structures. The data obtained from an ERT survey can be crucial for various applications, including environmental studies and construction planning. If you're looking for reliable solutions to conduct ERT surveys, consider leveraging the capabilities of Res3dinv, which offers advanced tools for interpreting your survey data effectively.

Resistivity meter. An instrument used to carry out resistivity surveys that usually has a current transmitter and voltage-measuring circuitry. Electrode. A conductor planted into the ground through which current is passed, or which is used to measure the voltage caused by the current.

There are two main types of resistivity survey: (1) area survey that maps a large area with a focus on a particular depth range and (2) electrical resistivity tomography (ERT) that images a vertical transect through the earth along a profile (Figures 1 and 2).

Res2DInv is a powerful 2D inversion software for ERT (DC) and IP data. The software offers a simple workflow from data import to inversion and visualization, while still offering full control over inversion parameters for advanced users.

Minimum requirements : Hard disc with at least 256 megabytes free space, and motherboard with at least 256 megabytes RAM. SVGA colour graphics system with screen resolution of at least 800 by 600 pixels and 256 colours.

How To Conduct An Electrical Resistivity Survey In 9 Easy Steps Select your field site. Decide on an interval for your electrodes. Lay out the tape measure. Hammer in the stakes. Connect the stakes, electrode cable, switch box, and SuperSting. Run a contact resistance test to check that all is connected right.

The method of measuring subsurface resistivity involves placing four electrodes in the ground in a line at equal spacing, applying a measured AC current to the outer two electrodes, and measuring the AC voltage between the inner two electrodes.
