NGRI hands over SLBC tunnel safety survey report to Uttam

The National Geophysical Research Institute (NGRI) has submitted a comprehensive survey report on the Srisailam Left Bank Canal (SLBC) tunnel works to Irrigation Minister N Uttam Kumar Reddy. The report highlights stress zones, seepage patterns, and factors behind the roof collapse. NGRI officials used advanced geophysical techniques to detect anomalies invisible to conventional inspections. The Minister appreciated NGRI's work and sought its active involvement in ongoing soil investigations for the Kaleshwaram Lift Irrigation Project.
