A new remote sensing technique to measure global reservoir storage


  • Colin Schultz


Nearly 60% of the world's large rivers are affected by dams, with more than 33,000 large dams holding back upward of 8300 cubic kilometers of water across the planet. Reservoirs are employed worldwide, helping to ensure regular access to fresh water, mitigate flash flooding, and maintain minimum river flow levels. However, not all reservoirs have adequate and accessible monitoring systems. Having no easily accessible method with which to monitor changing reservoir storage volumes hinders long-term planning and efforts to model the Earth's climate.
