Training Workshop on Ground Penetrating Radar

//Training Workshop on Ground Penetrating Radar
Loading Events

Introduction:

Ground Penetrating Radar, also known as GPR, Georadar, Subsurface Interface Radar, Geoprobing Radar, is a totally non-destructive technique to produce a cross section profile of subsurface without any drilling, trenching or ground disturbances. Ground penetrating radar (GPR) profiles are used for evaluating the location and depth of buried objects and to investigate the presence and continuity of natural subsurface conditions and features.

The method is being used extensively around the world for various applications including, but not limited to:

• Cavity mapping
• Concrete inspection
• Geological and hydro-geological investigations including mapping of bedrock topography, water levels, solution features (cavities), glacial structures, soils and aggregates.
• Engineering investigations to evaluate dams, sea walls, tunnels, pavements, roadbeds, railway embankments, piles, bridge decks, river scour, buildings and monuments.
• Location and evaluation of buried structures including utilities, foundations, reinforcing bars, cavities, tombs, archaeological artefacts, and animal burrows.
• Site investigations: location of buried engineering structures and underground storage tanks.
• Subsurface mapping for cables, pipes and other buried structures prior to trench-less operations.
• Defence & Law Enforcement applications like detection of buried tunnels, graves, unexploded ordinance, landmines, crevasses in snow bound areas, etc.

Objectives:

The incorrect and inappropriate use of GPR has over the years caused a great deal of damage to its reputation as a bona fide and reliable technology. The objective of this training workshop on GPR is to make the participants familiar with advanced data processing and interpretation techniques to derive maximum amount of information from data collected. After completing this course, user should be able to collect the GPR data, carry out basic as well as advanced data processing of data and interpret the results in a range of application areas.

Who Should Attend?

This 02 day training program will help professionals, engineers and geo-scientists dealing with shallow sub-surface investigation. The program is designed for new as well as experienced users of GPR equipment. The program will also help project owners hiring services of GPR surveys, enabling them understand capabilities and limitations of the method and derive maximum return on their investment on a GPR survey. The program is useful for individuals, organizations and professionals from following fields:

• Water, electrical, telecom, gas and other utility companies
• Construction/ Infrastructure organizations
• Trenchless companies
• Environment consultants/ contractors
• Army, Police, Para-Military forces and other law enforcement/ investigation agencies
• Concrete inspection agencies/ consultants/ contractors
• Road inspection authorities, vigilance officials
• Archaeological survey organizations
• Geologists, Hydro-geologists, Geophysicists and Civil Engineers
• Existing GPR users
• Fresh geophysicists/ engineers planning to pursue career in the field of GPR

Benefits:

The program will enable the participant to derive maximum information from GPR data and help them design the right GPR investigation program for a particular project requirement. It will also enable them to choose the right combination of antennas for varied geological conditions and resolution requirements.
