Modeling Phytoremediation of Soils
Publisher: American Society of Civil Engineers
Abstract: A numerical model that determines the uptake of cadmium by plants grown to remediate contaminated soils is developed in this study. The numerical model is first applied to the problem of copper uptake from contaminated ...
Modeling Heavy Metal (Cadmium) Uptake by Soil‐Plant Root System
Publisher: American Society of Civil Engineers
Abstract: Among various toxic substances that contaminate plants and enter the food chain, thereby posing health problems to human beings, heavy metals are particularly severe in their action. The behavior of heavy metals present ...
Modeling Water Uptake by Plant Roots
Publisher: American Society of Civil Engineers
Abstract: A mathematical model is developed that describes water uptake from soil by the roots of transpiring plants. Starting from a one-dimensional Richards equation with a root water extraction term, a partial differential equation ...
Estimation of Primary and Mechanical Compression in MSW Landfills
Publisher: American Society of Civil Engineers
Abstract: The density of municipal solid waste (MSW) plays a significant role in the computation of landfill settlement. A methodology is developed to compute the primary and mechanical compression considering the landfill density ...
Postclosure Long-Term Settlement for MSW Landfills
Publisher: American Society of Civil Engineers
Abstract: A mathematical model is developed to estimate the settlement attributable to biodegradation for municipal solid waste (MSW) landfills incorporating the effects of pH, temperature, and moisture content. The post closure ...
Groundwater Flow and Contaminant Transport Simulation with Imprecise Parameters
Publisher: American Society of Civil Engineers
Abstract: A methodology has been developed in this study wherein a genetic algorithm (GA) is used to find a global optimal solution to a groundwater flow and contaminant problem by incorporating an artificial neural network (ANN) ...
Discussion of “Remediation System Design with Multiple Uncertain Parameters Using Fuzzy Sets and Genetic Algorithm” by Jiabao Guan and Mustafa M. Aral
Publisher: American Society of Civil Engineers
Thickness of Compacted Natural Clay Barriers in MSW Landfills
Publisher: American Society of Civil Engineers
Abstract: Natural clay deposits and compacted clay liners are used as landfill barriers; however, there is no consensus on what an appropriate thickness of the barrier ought to be, due to difficulties encountered while analyzing ...
Potential Well Locations in In Situ Bioremediation Design Using Neural Network Embedded Monte Carlo Approach
Publisher: American Society of Civil Engineers
Abstract: An optimal groundwater remediation design problem generally requires determination of the location of extraction and injection wells and their pumping and injection rates once the well locations are selected. According to ...
Health-Risk-Based Remedial Alternatives for Contaminated Aquifer Management
Publisher: American Society of Civil Engineers
Abstract: In the risk-based management approach, the risks associated with human health and the environment in a contaminated site are evaluated and corrective measures are undertaken to reduce the risk level to acceptable limits. ...
