This third volume is devoted to the tunnelling and underground construction in connection with hydro-power development. During the last 30 years approximately 150 underground powerhouses and more than 3000 km of hydropower tunnels have been excavated in Norway. Some of the experiences from the extensive planning and construction works are presented in the 18 papers of this volume. As in the preceding volumes some of the papers have been published before, while others are written specifically for this volume.
