Geophysical Investigation - Jalkranti Groundwater Survey Center

About Geophysical Investigation

We use electrical resistivity techniques to analyze subsurface formations and locate aquifers accurately. A geophysical investigation uses non-invasive methods to study the Earth's subsurface by measuring physical properties like electrical resistivity, seismic wave propagation, and magnetic fields.

This data is used to create a map or model of the underground to understand geological structures, locate buried features, and assess resources or potential hazards, often without physical excavation. Common applications include groundwater exploration, mineral resource discovery, and site assessments for construction or environmental cleanup.

What it is

A method for exploring and mapping the subsurface by measuring physical properties from the ground's surface, within boreholes, or from the air.
It is a non-invasive or minimally invasive technique, meaning it disturbs the site very little compared to traditional drilling or excavation.
Data is collected through various methods that analyze seismic, electrical, electromagnetic, gravitational, and magnetic fields.

Key Applications

Civil Engineering

Determining subsurface geological conditions, locating buried utilities, and assessing foundation properties for construction projects.

Resource Exploration

Finding mineral deposits and mapping groundwater resources for sustainable extraction.

Environmental Assessment

Identifying and monitoring ground contamination and locating buried waste.

Archaeology

Locating buried artifacts and structures without disturbing the site.

Common Methods

Electrical Resistivity Tomography (ERT): Measures the electrical resistance of the soil to identify features like cavities and areas of different porosity.
Seismic Refraction: Analyzes the speed of seismic waves to determine layer depths and boundaries between materials.
Ground-Penetrating Radar (GPR): Uses radar pulses to detect objects and features underground.
Multichannel Analysis of Surface Waves (MASW): Models shear wave velocities to create subsurface profiles.
