ORIZON uses specifically designed geophysical techniques for river crossings investigations. Generally using conventional investigations, area under the flowing river is not mapped and is interpolated between the two vertical or inclined bore holes on the bank of the river which may not give adequate information on bed rock conditions. Many a times large boulders encountered during the conventional drilling methods for geotechnical investigations are misinterpreted as Bed rock which may mislead the engineers while designing the foundations. ORIZON uses a combination of Electrical Resistity Method and Seismic Refraction Method to overcome this limitation and maps the bed rocks precisely. Final results are presented as Geological Cross-sections of the river providing information on the bed rock profile. Geophysical techniques have capability of mapping the contrast between localized anomalies in bed rock, gravels or alluvial channels. Geophysical Techniques are generally used for bed rock profiling for geotechnical applications and examination / inspection of foundations of bridges.
