The Netherlands is inherently challenged by water, as a large part of the country lies below sea level and several major rivers in North-western Europe cross the country. The most prevalent form of protection from coastal and river floods in the Netherlands includes approximately 22,000 km of earthen dikes, of which 3800 km are primary flood defens...

Dissociation of methane hydrates in shallow marine sediments due to increasing global temperatures can lead to the venting of methane gas or seafloor destabilization. Along the U.S. Atlantic margin there is a well-documented history of slope failure and numerous gas seeps have been recorded. However, it is not fully understood whether the observed ...
In most civil engineering projects, the risk of slope failure has to be considered for allexcavations performed until the project is completed. The risk is founded in the uncertaintiesof the geotechnical properties of the soil that the excavations are performed in. With the riskof slope failure follows the risk towards the project budget, delays ve...

In this study, dynamic centrifuge model tests were performed for sand slopes under different earthquake ground motions and slope angle to characterize the seismic performance of slopes. Four groups of tests under varying seismic input amplitude were conducted. Under the action of increasing earthquake intensity, the rigidity of the soil decreases a...

Abstract—We present the results of laboratory studies of slope failure criteria by dynamic impulse loading in the range of peak ground velocities (PGV) between 0.003 and 1.3 m/s and peak ground accelerations (PGA) between 0.01 to above 170g. Critical parameter values of the dynamic loads acting on model slopes are established. The minimum PGA value...

The physical, geochemical, and clay mineralogical properties are location dependent and influence landslide, yet this relationship is understudied in the Cameron Highlands. Therefore, this study demonstrates the effect of the selected physical–geochemical properties and clay mineralogy on landslide susceptibility (LS) in the Cameron Highlands, Mala...
The Lansdowne Bank is a partly drowned, isolated carbonate platform of around 4000 km2 located 300 km west of New Caledonia, in the SW Pacific Ocean, in water depths of 20 to 100 m. New multibeam bathymetric data, high resolution seismic reflection profiles and sediment gravity cores have been acquired on the bank top and adjacent slopes. This data...

The stability of an arching slope in deformable materials above strong rocks strongly depends on the shape and width of the span. Equations for a free surface problem that incorporate these two parameters were derived using a simplified two-dimensional arching slope model, and were validated using physical model tests under 1g and centrifugal condi...

Numerical scenario simulation may serve as an efficient and powerful tool for hazard assessment, but it often suffers from the lack of a definite failure surface before the occurrence of failure. In the present study, an idealized curved surface (ICS) is proposed for mimicking the sliding surface in the numerical simulation. Different from the conv...

Landslide is the most frequent geo-environmental natural hazard which significantly affect human life and environment. It is the natural hazard when occurs especially in hilly regions mainly along highway corridor, results in obstruction to traffic flow. The road network of a developing country plays a vital role in its overall development. Therefo...
