Soft Ground Tunnel Design is a textbook that teaches the principles of tunnel and underground space design in soft ground. ‘Soft ground’ refers to soil, in contrast to rock. The book focuses on stability, prediction of ground movements and structural design of the lining. It shows that the choice of excavation and support methods depends on ground stability; limitation of damage to the existing built environment; and health, safety and environmental considerations.

Ultra-Wideband Surveillance Radar is an emerging technology for detecting and characterizing targets and cultural features for military and geosciences applications. To characterize objects near and under severe clutter, it is necessary to have fine range and cross range resolution. The resultant wide bandwidth classifies the systems as ultra-wideband, requiring special treatment in system technology and frequency allocation.
