Landslide monitoring and early warning systems are the most successful countermeasures to reduce fatalities and economic losses from landslide hazards. The traditional strategies such as GPS and extensometers are relatively expensive and difficult to be installed in steep, high mountains. In this study, a MEMS (Micro Electro Mechanical Systems) based multivariate wireless monitoring sensor unit...

The soil–water characteristic curve is an important tool to evaluate the water-holding capacity of unsaturated soil. Plant roots can affect matric suction soil and permeability Therefore, morphological characteristics plant will lead difference in between slope plant-covered slope. This study aims investigate effect Vetiver root morphology on curves hydrological distribution root–soil system wa...

To investigate unsaturated soil-water interaction at micro-scale, this study extends the numerical manifold method (NMM) by incorporating a coupling model considering specific capillary water distribution and force calculation. The soil skeleton is constructed generation algorithm with random polygons. more realistically capture between grains water, mechanics-based geometric proposed to iterat...

Pile foundations are widely used in regions with expansive soils to transfer the loads from superstructures a rigid soil stratum, thereby alleviating stability and deformation problems. However, current design procedures for pile typically based on saturated mechanics principles assuming drained conditions, despite fact surrounding piles an unsaturated state. Volume changes of induced by matric...

• Soil shear strength, τ, was measured in intact topsoil at six matric potentials. The preload suction stress (PSS) estimated from water saturation and suction. Normal load, PSS, density, clay organic matter explained >90 % of variation τ. model predicted well τ for two independent data sets. the trend also subsoil Distortion soil stresses during field traffic may be even more damaging to funct...

The rhizosphere is one of the major components in soil–plant–atmosphere continuum which controls flow water from soil into roots. Plant roots release mucilage capable altering physio-chemical properties this region. Here, we showed how impacted on hydraulic properties, using simple experiments. An artificial rhizosphere, treated or not with mucilage, was placed a sample and suction applied to m...

Filtered tailing is a relatively-environmentally friendly technique due to the recovery of water during process dehydration. This was recently developed and therefore there are few studies available compared research on conventional tailings. work focuses behaviour filtered copper under an unsaturated condition, studying effect self-compaction by self-weight which triggered deposition through 1...

The soil water retention curve (SWRC) or soil–water characteristic (SWCC) is a fundamental feature of unsaturated that simply shows the relationship between suction and content (in terms degree saturation volumetric gravimetric content). In this study, applications SWRC SWCC have been extensively reviewed, taking about 403 previously published research studies into consideration. This was achie...
