Brief Description
Description : | This technology employs heliborne transient electromagnetic (TEM) surveying methods to map subsurface geological formations and identify aquifer systems over large areas. The system is mounted on a helicopter, which transmits electromagnetic signals into the ground and measures the response from subsurface materials. Variations in electrical conductivity are analyzed to distinguish between different geological layers, enabling accurate detection of groundwater-bearing formations, aquifer thickness, and depth. The technology allows rapid data acquisition across extensive and inaccessible terrains, making it highly effective for regional-scale groundwater assessment. It supports scientific planning and sustainable management of water resources by providing high-resolution subsurface information for identifying potential groundwater zones.
Key Features: • Uses airborne transient electromagnetic method for subsurface investigation • Enables mapping of aquifer depth, thickness, and lateral extent • Provides high-resolution data on subsurface conductivity variations • Covers large and inaccessible areas efficiently using helicopter-based surveys • Supports identification of potential groundwater zones for resource planning • Useful for hydrogeological studies, groundwater exploration, and water resource management • Reduces time and effort compared to conventional ground-based survey methods |
