The Tennessee Valley Authority said it was taking the unusual flood-prevention measure of spilling 1.5 million gallons of water per second through the Kentucky Dam near Paducah from the Tennessee River into the Ohio River.
In Pakistan, for example, the International Centre for Water Hazard and Risk Management (ICHARM), created under the auspices of UNESCO, and the Japan Aerospace Exploration Agency (JAXA) designed the Integrated Flood Analysis System (IFAS), a risk-prevention system using data obtained via satellite.
With projects such as Meixi Lake City, starting from scratch brings significant benefits not open to -- easily at least -- existing conurbations, such as combining water transport with energy production, superior flood prevention and urban agriculture.
