We present an experimental approach for investigating the potential for bioremediation of Ž . volatile organic compounds VOCs in fractured rock vadose zones. The experimental work was performed with rock samples and indigenous microorganisms from the site of the United States Ž . Department of Energy’s Idaho National Engineering and Environmental Laboratory INEEL , located in a basalt flow basi...

The induced cracks on the concrete lining of the intake pressure tunnels may cause the water seep into the surrounding media leading to develop a hydro pressure on the external surface of the lining. In the common design practice, the lining can be designed to tolerate with this pressure using the Schleiss method. However, when the tunnel is constructed above the underground water, the seepage ...
