Development of a landslide hazard map for the island of Puerto Rico
… considered in this study are elevation, slope aspect, slope angle and land use. This study employed data for a total of 2,966 landslides. The elevation and land use analysis was conducted on the entire landslide dataset, while the slope aspect and slope angle analysis was conducted on a …

Seepage through longitudinal drainage trenches
… the flow patterns caused by a trench drain in a slope. The experimental variables include the trench spacing (w), seepage depth (h), and slope angle (theta). In the experimental program, four values of slope angle, three values of trench spacing and three values of seepage depth were considered. …

Identifying Key Factors Affecting Translational Landslides in Part of the Yakima Fold and Thrust Belt, Washington State
… the folded CRBs and sediment layers are dip slope angle, sediment composition and hillslope base removal. Using ArcGIS 10.5 mapping software, my research combines previous mapping efforts, the Washington State Landslide Inventory, and the Washington DNR Lidar Portal to evaluate landslide …

An experimental study on mixing induced by gravity currents on a sloping bottom in a rotating fluid
… in a tank with homogeneous ambient fluid. The slope angle, rotation rate, reduced gravity, and flow rate of the dense source water were changed for the experiments. The mixing was quantized by measuring the density of the ambient fluid, dense source water, and the bottom water collected at the …

Role of Vegetation and Environmental Characteristics on Slope Stability in Northwest Arkansas
<p>Slope failure continues to pose risks to society because knowledge of environmental factors and their interactions are unclear and possibly misunderstood. This misunderstanding leads to generalizations about slope failure susceptibility mapping, despite knowing that slope failures are likely the …

Soil Slope Failure Investigation Management Systems
Highway slopes are exposed to environmental and climatic conditions, such as deforestation, cycles of freezing and thawing weather, heavy storms etc. Over time these climatic conditions can influence slope stability in combination with other factors such as geological formations, slope angle and …

Seepage in earth slopes with longitudinal drainage trenches
… An apparatus capable of simulating different slope angles and trench spacing was utilized in this study. By using this apparatus it was possible to obtain data regarding flow pattern, pressure heads, saturation time, influence of slope angle (theta), the trench spacing (W = 2w) and seepage …

Shoreline recession: past, present, and future, Lake Sakakawea, North Dakota
… include: bank height, effective fetch, offshore slope angle, beach width, mean grain size, percentage of coarse beach clasts, angle between the shoreline and dominant wind, and bank orientation with respect to the sun. These variables, along with the average monthly rate of recession, were …

Working Up Hills: Dynamics over Sloping Topography with Bottom-Enhanced Diffusion
… simulating the desired phenomena, notably an upslope flow along the topography, and had otherwise comparable results. Two diagnostics were used for analyzing both models: the minimum value of streamfunction is a proxy for flux of a bottom boundary layer, and an estimate of thickness for the …

Specialized Inter-Particle Interaction Lbm For Patterned Superhydrophobic Surfaces
… roughness can manipulate the droplet contact angle, thus providing an opportunity to control the droplet wetting characteristics. The Shan and Chen (SC) lattice Boltzmann model (LBM) is a good numerical tool, which holds strong potentials to qualify for simulating droplets wettability. This is …

An assessment of the relationships between the surface soil properties and components of slope and vegetation in the Upper Wadi Bishah Basin, Saudi Arabia
… between them, as well as their relationship with slope components in the Upper Wadi Bishah basin, south-west Saudi Arabia. It is based mainly on quantitative and laboratory analysis, and provides a scientific basis for exploitation of the basin's slopes and conservation of its soil and …

Triggering Mechanisms and Stabilization of a Massive Pit Slope Failure
The 2013 Bingham Canyon slope failure was probably the largest non-volcanic landslide in NorthAmerican history. Because it took place in an active mine with substantial monitoring systemsalready in place, its geological setting and progress to failure are better understood than mostlandslides. The …

Ocean mixing and heat transport beneath Antarctic ice shelves
… study examines the interplay between ice base slope, mixing across the pycnocline, and basal melting, focusing on slopes appropriate to the grounding zone of small Antarctic ice shelves and to the flanks of relatively wide basal channels. The simulations reveal an unexpected relationship …

The Influence of The Burrowing Mammal Tamias Striatus on The Soil Creep Process
… the effect which organisms have on geomorphic slope processes in east central Illinois, U.S.A. Soil creep measurements were made on both a short-term (biweekly) and a long-term (one year) basis, using t-bars and Young pits respectively. Surface sediment transport was monitored with the use of …

The criminal career profile : a measure of criminal careers
… of the seriousness of offending, and the slope or angle of the regression line can be considered a quantitative index of criminal career severity. Larger slopes or angles (used in this Program of Research) suggest more serious criminal careers. Conversely, smaller slopes or angles suggest …
