Web-based 'green' monitoring system for Ganga
GS Paper - 3 (Space Technology)
An Indo-US project has spurred Indian Institute of Technology (IIT) Kanpur to develop a web-based system to monitor the “health” of the Ganga. The project has been jointly sponsored by the Department of Science and Technology, Government of India, and Indo-US Science and Technology Forum (IUSSTF).
- The low-cost, multi-parameter, water quality monitor named Niracara Svayamsasita Vedh Shala (NSVS) consists an array of sensors and auto sampler on a stationary platform, which is semi-submersible, all-weather, robust and perfectly stable.
- The “Aquatic Autonomous Observatory” would enable in situ monitoring, real-time data transmission and web-based visualisation of Ganga, IIT Kanpur said.
- The new system has now been installed at the Laxman Ghat on the banks of the Ganga in Bithoor, a town in Kanpur.
- With its large riverine network, India battles frequent floods, foam-filled toxic water bodies, unexpected rise in water levels, polluted rivers and so on, impacted by global warming and human activity.
How will it work?
- The NSVS system can sense three parameters namely, pH (a scale to measure acidity/alkalinity), conductivity and dissolved oxygen capacity of water.
- This can be further utilised to estimate total dissolved solid, specific gravity and presence of metallic ions in water.
- It also autonomously collects data every 15 minutes and reports it through a wireless network to the institute.
- For self-sustenance, the platform is equipped with energy harvesting systems comprising solar cells and a Vortex Induced Vibration system that can extract energy from the flow of river.
