Which technology is being leveraged for precise drain mapping along the Ganga main stem under the Namami Gange Mission?

The correct answer is Drone and LiDAR Technology.

In News

• The Union Minister of Jal Shakti, C.R. Patil, emphasized the use of Drone and LiDAR technology for advanced drain mapping along the Ganga main stem under the Namami Gange Mission.

Key Points

• Drone and LiDAR (Light Detection and Ranging) technology enables high-resolution mapping of drainage systems along the Ganga.
• These tools help identify pollution sources and monitor wastewater discharge with precision.
• The data-driven approach ensures targeted interventions for river conservation and pollution control.
• The initiative aligns with the government’s goal of using advanced technology to rejuvenate the Ganga.

Additional Information

• LiDAR Technology
  • LiDAR (Light Detection and Ranging) uses laser pulses to measure distances and create detailed 3D maps.
  • It is highly effective for identifying terrain features, mapping water bodies, and assessing environmental changes.
• Namami Gange Mission
  • A flagship program aimed at cleaning and rejuvenating the Ganga River.
  • It includes projects on sewage treatment, riverfront development, wetland conservation, and pollution control.
• Environmental Flow (e-Flow) Compliance
  • Ensures regulated water discharge from Devprayag to Haridwar and up to Unnao in Uttar Pradesh.
  • Aims to maintain the ecological balance of the river system and improve water quality.
