About

Avadh Bihari Narayan is a geodetic scientist whose work sits at the critical intersection of natural hazard assessment and advanced remote sensing. His primary research focuses on landslide detection and monitoring, with a specific emphasis on the geologically sensitive Lesser Himalayan region. Narayan’s major contribution lies in pioneering a robust, multi-sensor geodetic framework for landslide investigation. He was the first in India to integrate Terrestrial Laser Scanner (TLS), Global Navigation Satellite Systems (GNSS), Robotic Total Station (RTS), and Multi-temporal InSAR (MT-InSAR) to study the Sirobagarh landslide in Uttarakhand. This comprehensive approach allows for the monitoring of ground deformation at varying spatial extents, from localized slope movement to broader tectonic influences. His most cited work (29 citations) demonstrates the power of this LiDAR and SAR interferometry-based methodology. By combining these techniques, Narayan provides a more complete and accurate picture of landslide dynamics, directly contributing to better risk assessment and mitigation strategies in a region prone to recurring, devastating landslides. His work represents a significant step forward in applying cutting-edge geodetic science to protect vulnerable communities.
