Extreme rainfall causes surface runoff to flow towards lowlands and subterranean facilities, such as subway stations and buildings with underground spaces in densely packed urban areas. These facilities and areas are therefore vulnerable to catastrophic submergence. However, flood modeling of underground space has not yet been adequately studied because there are difficulties in reproducing the...

Maximising space in our urban towns and cities remains one of the great challenges of the future. As the need to protect existing green areas grows amid ever increasing demands for more homes and work places, mass transit systems and modern infrastructure, so new approaches must be found to better utilise space available. Improved use of underground space offers new and exciting opportunities f...

Wireless underground sensor networks (WUSNs) consist of buried nodes, which are connected to subsurface underground sensors, and use electromagnetic (EM) waves for underground communications. WUSNs are capable of operating in environments where no other computer network has functioned before, and has the potential to provide real-time, robust, and energy efficient sensing, and communication in ...
