IIT Kanpur develops a self-sustaining monitoring system for the Ganga River.

Indian Institute of Technology Kanpur has developed a self-contained Aquatic Autonomous Observatory. The system can detect three main parameters: pH, conductivity, and the waters dispersed oxygen capacity in its current state.

The Indian Institute of Technology Kanpur has developed a self-contained Aquatic Autonomous Observatory, named Niracara Svayamsasita VedhShala (NSVS), for in situ monitoring, real-time data transmission, and web-based visualization of the river Ganga.The unit was installed at Laxman Ghat, Bithoor, by AR Harish, Dean of Research and Development, IIT Kanpur.The system can detect three main parameters: pH, conductivity, and the water's dispersed oxygen capacity in its current state.According to IIT Kanpur, this data can be used to calculate total dissolved solid (TDS), specific gravity, and the presence of metallic ions in water.

The platform is equipped with energy recovery modules such as solar cells and a special Vortex Induced Vibration (VIV) system that can extract electricity from the river's flow, according to the manufacturer.The project has been implemented by a team of earth scientists, mechanical, electrical, and aerospace scientists from the institute, led by Prof Bishakh Bhattacharya as the primary investigator.According to IIT Kanpur, the NSVS device has been developed as a low-cost, multi-parameter, water quality monitoring system that would include a plurality of sensors and an auto sampler on a fixed platform that is semi-submersible, all-weather, strong, and 100% stable.According to Prof. Abhay Karandikar, Director of IIT Kanpur, the Ganga is not only a river but also a cultural heritage for us, so it is our job to protect it from harm.

I congratulate the team led by Prof Bishakh Bhattacharya on the introduction of the NSVS system, which will enable real-time, in-situ monitoring of the river Ganga to ensure its healthyness.In addition, IIT Kanpur has recently launched a Ganga Atlas and a workflow that allows users to process and analyze declassified images of riverine environments at low cost by using an open-source framework.IIT Kanpur said it had conducted a study on the stability of dissolved heavy metals in the Ganga river, the effect of immersion of dead bodies in the river, and held a roundtable discussion on the rejuvenation of rivulets in the Ganga river basin, among other initiatives.
