upstream blankets, drains and cutoff walls are considered as effective measures to reduce seepage, uplift pressure and exit gradient under the foundation of hydraulic structures. to investigate the effectiveness of these measures, individually or in accordance with others, a large number of experiments were carried out on a laboratory model. to extend the investigation for unlimited arrangement...

The Shillong Plateau (northeastern India) constitutes the only significant topography in the Himalayan foreland. Knowledge of its surface uplift history is key to understanding topographic development and unraveling tectonic–climate–topographic coupling in the eastern Himalaya. We use the sedimentary record of the Himalayan foreland basin north of the Shillong Plateau to show that the paleoBrah...

Terrain generation finds many applications such as in CGI movies, animations and video games. This paper describes a new and simple-to-implement terrain generator called the Uplift Model. It is based on the theory of crustal deformations by uplifts in Geology. When a number of uplifts are made on the Earth’s surface, the final net effect is an average of the influence of each uplift at each poi...

Abstract In order to study the differential diagenesis of sandy conglomerate reservoirs in different tectonic units eastern Junggar Basin, and establish temporal sequence burial – hydrocarbon charging pore evolution, Upper Permian Wutonggou Formation reservoir Dongdaohaizi Sag Baijiahai Uplift, Basin are studied, based on observation thin sections under microscope, measurement scanning electron...

Timing of surface uplift of the Tibetan Plateau has received much attention because of proposed links between high topography and change in regional and global climate, southern Asian paleoecology, and ocean chemistry (Quade et al., 1989; Edmond, 1992; Prell and Kutzbach, 1992; Raymo and Ruddiman, 1992; Molnar et al., 1993; Derry and France-Lanord, 1996). However, the actual vintage of high ele...

Rolling-based seismic isolation systems, in which rollers of circular or non-circular section are used, are less expensive and easier to manufacture. However, this type of isolation suffers from either lack of restoring or re-centering capability, or weakness against uplift forces. To resolve the first shortcoming the use of elliptical as well as pillow-shape rolling parts has been suggested, a...

Abstract High-elevation, low-relief surfaces are widespread in many mountain belts. However, the origin of these has long been debated. In particular, southeast Tibetan Plateau extensive perched above deep valleys and headwaters three world's largest rivers (Salween, Mekong, Yangtze Rivers). Various geologic data geodynamic models show that belts grow first to a certain height then laterally an...
