RISImproving Hydraulic Conductivity Estimation for Soft Clayey Soils, Sediments, or Tailings Using Predictors Measured at High-Void Ratio
Publisher: ASCE
Abstract: Consolidation parameters are required to support the disposal management of soft soils or mine tailings. The estimation of these parameters from simple correlations using easily measured properties can be advantageous, and ...
Evaporation, Unsaturated Flow, and Salt Accumulation in Multilayer Deposits of “Paste” Gold Tailings
Publisher: American Society of Civil Engineers
Abstract: Both the geotechnical and geoenvironmental performances of surface deposited “paste” mine tailings are strongly influenced by desiccation, rewetting after precipitation, as well as interlayer flow. All these processes ...
Discussion of “Stiffness and Strength Governing the Static Liquefaction of Tailings” by F. Schnaid, J. Bedin, A. J. P. Viana da Fonseca, and L. de Moura Costa Filho
Publisher: American Society of Civil Engineers
Piecewise-Linear Formulation of Coupled Large-Strain Consolidation and Unsaturated Flow. I: Model Development and Implementation
Publisher: American Society of Civil Engineers
Abstract: A mass-conservative formulation of one-dimensional (1D) coupled large-strain consolidation and unsaturated flow using a piecewise-linear formulation is developed. The volume and water-content changes in the unsaturated ...
Estimation of Soil–Water Characteristic Curve of Clayey Till Using Measured Pore-Size Distributions
Publisher: American Society of Civil Engineers
Abstract: The soil–water characteristic curve (SWCC) of fine-grained soils is usually determined experimentally. In the design of mine waste covers and landfill liners, the unsaturated hydraulic conductivity function,
Early Responses to Climate Change: An Analysis of Seven U.S. State and Local Climate Adaptation Planning Initiatives
Publisher: American Meteorological Society
Abstract: State and local governments in the United States manage a wide array of natural and human resources that are particularly sensitive to climate variability and change. Recent revelations of the extent of the current and ...
Impact of Desiccation on Monotonic and Cyclic Shear Strength of Thickened Gold Tailings
Publisher: American Society of Civil Engineers
Abstract: Various forms of thickened or high-density tailings, characterized by exhibition of a yield stress that facilitates deposition in gently sloped stacks, are increasingly used for a variety of mining operations. Although ...
Piecewise-Linear Formulation of Coupled Large-Strain Consolidation and Unsaturated Flow. II: Testing and Performance
Publisher: American Society of Civil Engineers
Abstract: A piecewise-linear formulation for simulating coupled large-strain consolidation and unsaturated flow using a mass-conservative and noniterative solution was developed in a companion paper and implemented in a proposed ...
Equally Unprepared: Assessing the Hurricane Vulnerability of Undergraduate Students
Publisher: American Meteorological Society
Abstract: tudents have been described as being both particularly vulnerable to natural disasters and highly resilient in recovery. In addition, they often have been treated as a distinct, homogeneous group sharing similar characteristics. ...
Renewable Generation in the London Built Environment
Publisher: American Society of Civil Engineers
Abstract: This paper critically reviews the current requirement for a 10% offset of carbon emission that should be obtained from on-site renewable and other carbon-saving energy sources installed in new office buildings in London ...
