Preparation and characterization of powdered and granular activated carbon from Palmae biomass for mercury removal
Two forms of activated carbon (i.e., granular and powdered forms) used to test mercury removal in solution. These activated carbons were obtained...

Crown-Like Baffle System against Rock Avalanches: Energy Dissipation Mechanism and Numerical Verification
In mountainous areas, rock avalanches swarm downslope leading to large impact forces on structures. Baffle systems are usually set up in torrent...

A review of water rock interaction in underground coal mining: problems and analysis
Underground coal mining has a strong disturbance on surrounding rock strata, causing inevitable water inflow into mined spaces, which seriously...

Multi-phase flow simulation of impulsive waves generated by a sub-aerial granular landslide on an erodible slope
This study uses a multi-phase flow model to examine the impulsive waves generated by collapse of steep slopes at a water body. Possible effects of...

Mechanics of Lake Ice
Ice in the Earth’s nature is mechanically complex medium as its properties depend on the space and time scales. In short-term loading ice is elastic,...

Analyzing landslide-induced debris flow and flow-bridge interaction by using a hybrid model of depth-averaged model and discrete element method
The Minbaklu Bridge, an essential segment of the southern cross-island expressway in Taiwan, was destroyed owing to debris flow in the Yusui Stream....

Electro-cementation of calcareous sand using colloidal silica (CS) nanoparticles and alumina powder
The research investigates the effectiveness of a ground improvement technique that involves the electro-cementation of an onshore calcareous sand...
-
Flume Modeling of Debris Flows
Debris flows are unique compared to other types of landslides (e.g., rock avalanches; dry granular flows) because their dynamics are governed by both...
-
Evaluation of Combined Base Soil Erodibility and Granular Filter Efficiency
Filters managed in zoned dams are designed according to criteria based on the grain size distribution of both filter and eroded soil. However, the...
-
Real-scale measurements of debris-flow run-ups
Rapid mass movements, such as debris flows, endanger alpine areas due to their destructive nature. In order to counteract these dangerous flows, it...

Experimental study on shear failure mechanism of loose spoil soil considering the adverse factor of water
Loose spoil soil (LSS) is a kind of granular material with unstable structure, for which the deformation and even failure should be induced by...
-
Three-dimensional modeling of the impact behavior of debris flows in areas affected by earthquakes
The 2008 Wenchuan earthquake triggered many landslides and caused high volumes of loose solid material to collect in gully drainage areas; over time,...
