Abstract Bener Dam Diversion Tunnel is located in two rock units such as andesite and breccia. Based on the engineering geology investigation, subsurface tunnel will penetrate breccia with good mass quality (fresh-moderately weathered), while surrounding consist of breccias moderate poor quality. Geological conditions are used basis for stability analysis excavation methods determining primary ...
The ‘range of variability approach’ (RVA) and mapping technique are used to investigate the spatial variability of hydrologic alterations (HA) due to dam construction along the middle and lower Yellow River, China, over the past five decades. The impacts of climate variability on hydrological process have been removed during wet and dry periods and the focus is on the impacts of human activitie...
