This paper presents recommended methodologies for the quantitative analysis of landslide hazard, vulnerability and risk at different spatial scales (site-specific, local, regional national), as well verification validation results. The described focus on evaluation probabilities occurrence types with certain characteristics. Methods used to determine distribution intensity, characterisation elements risk, assessment potential degree damage quantification those perform are also described. is...
Abstract The paper outlines the theory of generalized plasticity in which yield and plastic potential surfaces need not be explicitly defined, shows how a very effective general model describing behaviour sands clays under monotonic or transient loading can developed. is currently one simplest yet most ones for full range behaviour. hierarchical structure limits number parameters have to experimentally determined given material those strictly necessary problem at hand. A discussion used...
AbstractPrevious research suggests that minority residential areas have a disproportionate likelihood of hosting various environmental hazards. Some critics responded the contemporary correlation race and hazards may reflect post-siting move-in, perhaps because risk effect on housing costs, rather than discrimination in siting. This article examines siting move-in hypotheses Los Angeles County by reconciling tract geography data over three decades with firm-level information initial dates...
In the past decades, flow-like catastrophic landslides caused many victims and important economic damage around world. It is therefore to predict their path, velocity depth in order provide adequate mitigation protection measures. This paper presents a model that incorporates coupling between pore pressures solid skeleton inside avalanching mass. A depth-integrated, coupled, mathematical derived from velocity–pressure version of Biot–Zienkiewicz model, which used soil dynamics. The equations...
Past research on “environmental justice” has often failed to systematically link hazard proximity with quantifiable health risks. The authors employ recent advances in air emissions inventories and modeling techniques consider a broad range of outdoor toxics Southern California calculate the potential lifetime cancer risks associated these pollutants. They find that such are attributable mostly transportation small-area sources not usually targeted large-facility pollution emissions....
Environmental justice offers researchers new insights into the juncture of social inequality and public health provides a framework for policy discussions on impact discrimination environmental diverse communities in United States. Yet, causally linking presence potentially hazardous facilities or pollution with adverse effects is difficult, particularly situations which populations are exposed to complex chemical mixtures. A community-academic research collaborative southern California...
The behaviour of all geomaterials, and in particular soils, is governed by their interaction with the pore fluid. mechanical model this when combined suitable constitutive discription solid phase efficient, discrete, computation procedures, allows most transient static problems involving deformations to be solved. This paper describes basic procedures development a general purpose computer program (SWANDYNE-X). results computations are validated comparison experimental obtained on physical...
:Environmental justice advocates have recently focused attention on cumulative exposure in minority neighborhoods due to multiple sources of pollution. This article uses U.S. EPA's National Air Toxics Assessment (NATA) for 1996 examine environmental inequality California, a state that has been recent innovator policy. We first estimate potential lifetime cancer risks from mobile and stationary sources. then consider the distribution these using both simple comparisons multivariate model...

Abstract This paper extends the bounding surface, generalized plasticity, model of Part I to reproduce behaviour sands under both static and transient loading. The essential features first are preserved but following changes introduced: shape yield surface is modified. A non‐associative flow rule introduced. hardening parameter includes not only volumetric also deviatoric plastic strain. Plastic strains introduced during unloading. Each these modifications can be separately in a hierarchical...
Studies have identified relationships between air pollution and birth weight, but been inconsistent in identifying individual pollutants inversely associated with weight or elucidating susceptibility of the fetus by trimester exposure.

Regulatory agencies, including the U.S. Environmental Protection Agency (US EPA) and state authorities like California Air Resources Board (CARB), have sought to address concerns of environmental justice (EJ) advocates who argue that chemical-by-chemical source-specific assessments potential health risks hazards do not reflect multiple social stressors faced by vulnerable communities. We propose an Justice Screening Method (EJSM) as a relatively simple, flexible transparent way examine...
The entrainment of channel-path material plays an important role during runout many rapid landslides. Such a mechanism is able to change the mobility flow significantly, through changes volume and rheology. purpose this paper use mathematical, rheological constitutive models analyse effect on analysis results. After brief review classification some well-established erosion laws, simple, yet effective, empirical formula for rate has been selected, implemented in continuum mechanics-based...
Policies to mitigate climate change by reducing greenhouse gas (GHG) emissions can yield public health benefits also of hazardous co-pollutants, such as air toxics and particulate matter. Socioeconomically disadvantaged communities are typically disproportionately exposed pollutants, therefore policy could potentially reduce these environmental inequities. We sought explore potential social disparities in GHG co-pollutant under an existing carbon trading program-the dominant approach...
