Alterant tomography h*s been evaluated for its ability to de­ lineate itfsitu water flow paths in a fractured welded-tuff rock mass, The evaluation involved a field experiment in which tomographs of electromagnet attenuation factor (or attenuation rate) at 300 MHz were made before, during, and after the introduc­ tion to the rock of two different water-based tracers: a plain water and dye solut...

based on volume-averaging concepts, liquid migration along subvertical fractures typically is predicted to be Field and laboratory tracer experiments were conducted to investisubject to strong matrix imbibition into the partially satugate the extent of tracer imbibition and penetration into unsaturated, fractured rock matrix at Yucca Mountain, Nevada. Field experiments rated rock (e.g., Wang an...

Various methodologies are available today in engineering professional practice to analyse structures, in particular in the field of masonry structures. Many of the methods are derived from reinforced concrete frames but sometimes they suffer of lack of comprehensive experimental validation due to difficulties to simulate the many different kinds of masonries and they suffer from lack of critica...
