Because of the nitrogen pollution problem in groundwater, migration conversion mechanism groundwater level fluctuations was analyzed. Technology and methods through indoor experiments theoretical analysis were used to study coarse sand, medium fine sand fluctuation aeration zone saturated under situation distribution characteristics, revealing with mechanism. The experimental results showed tha...

Artificial water pumping and rainfall will induce groundwater level fluctuations, leading to large-scale karst collapse. Therefore, the combination of physical model test FLAC3D numerical simulation is adopted simulate soil cave collapse caused by three different initial fluctuations in this paper. The influence various heights on variation water-gas pressure, pressure overlying layer, deformat...

Abstract Waterlogging (WL) refers to the process by which water flow is resisted in vertical and horizontal directions thus stagnates for a short or long span of time; it induced combination human natural factors. In southwestern region Bangladesh, including Natore District, WL significant issue that needs be addressed if agricultural activity successful. This study aimed identify surface Distr...

Groundwater level plays an important role in triggering landslides. In this paper, Distinct Element Method is used to investigate the impact of groundwater table fluctuation on stability jointed rock slopes. For purpose, 110 cases including different number joint sets, friction angles, spacings, and angles are considered influence changing a slope investigated through series parametric studies....
