Abstract Lateral intake structures suffer from sediment deposition and instability of flow path which may have a negative influence on the efficiency power plants that use river intakes as primary source for their cooling system. This study aims to experiment usage submerged vanes mitigation method determine effectiveness in decreasing deposition. A numerical model was constructed using DELFT3D...

Here, we show results of an unprecedented LiDAR dataset quantitatively determining the lateral bedrock erosion a narrow limestone gorge during extreme hyperconcentrated flow. The comparison two point clouds prior and post to June 15 th flow event provide information about massive breakout particles abrasion channel walls. With multiscale model cloud analysis, can that from 0.0001 m 3 3.5 were e...

While excavated discharge channels are often used for the emergency treatment of landslide-dammed lakes, erosion channel a landslide dam is complex and rarely monitored on site. This work presents quantitative monitoring method based three-dimensional terrestrial laser scanning technology (TLS) analyzing then applies this to evaluate engineering 2018 Baige lake in 2019. The proposed uses TLS ac...

Recent sedimentological and morphological evolution of an island in the River Loire (France) was investigated using the Cs method. This study describes the morphological adjustment of the island in the last 50 years, which corresponds to the increased bed incision of this sandy, multiple-channel environment because of, among other things, the increase in sediment extraction up to 1995. The resu...

Coal mine reuse involves complex environments such as chemical erosion and dynamic perturbation. Therefore, the effect of on behavior red sandstone was studied by split Hopkinson pressure bar (SHPB) tests under strain rates 70~125 s?1. The full-field deformation sample then recorded through high-speed 3D digital image correlation (3D-DIC) technique. characteristics, especially lateral strain, w...

Bilateral infusions of N-methyl-D-aspartate (NMDA) into the lateral hypothalamus (LH) produce gastric erosions in rats. The present study attempted to determine the neural pathways that mediate this effect. In order to interrupt axonal transmission, knife cuts (KC) were made in different planes adjacent to the LH. In separate groups of rats, KC were made anterior, posterior or lateral to the LH...

The present study investigated whether neurons in the lateral hypothalamus (LH) play a role in the occurrence of gastric ulcerations induced by cold-water restraint. The first experiment indicated that bilateral N-methyl-d-aspartate (NMDA) lesions of the LH (20μg/1μl per side) reduced the amount of gastric ulceration induced by cold-water restraint. In the second experiment, the NMDA antagonist...
