As a consequence of the poor implantation sanitation systems, more than 80% wastewater from human activity is dumped, which poses threat to public health and generates water stress. In contrast, its depuration reuse for irrigation improves efficiency management cycle reduces use fresh water. context grey purification in rural areas Europe, constructed wetlands are preferred option. Furthermore,...

Combining image processing and optimization techniques, we automatically align a lattice of points (atoms) with horizons and faults in a 3-D seismic image. Connecting these points yields an unstructured space-filling polyhedral (atomic) mesh. This single data structure can integrate multiple tasks, such as seismic interpretation, reservoir characterization, and flow simulation, thereby reducing...

[1] We study channelization and slope destabilization driven by subsurface (groundwater) flow in a laboratory experiment. The pressure of the water entering the sand pile from below as well as the slope of the sand pile are varied. We present quantitative understanding of the three modes of sediment mobilization in this experiment: surface erosion, fluidization, and slumping. The onset of erosi...
