Abstract: A granular filter is required to satisfy two requirements of retention and hydraulic conductivity. The current design approaches are based on the representative grain sizes for retention and hydraulic conductivity requirements. ...

Abstract: Controlling methane emissions from landfills has been a significant concern over the last decades. Researchers have identified the use of landfill cover with oxidative capacity (biocover) as a promising solution to mitigate ...

Abstract: The emission of landfill gases from dump sites due to anaerobic biodegradation of waste is a matter of increasing public concern as they significantly contribute to global warming. In order to assess the methane emissions ...

Abstract: Exploitation of the natural methane oxidation process in biotic systems in landfills through improved design offers an inexpensive way of reducing methane emissions. Maximization of this oxidation efficiency can promise a ...

Abstract: The support design for rock tunnels involves a complex problem because of the various types of uncertainties present in rock mass properties; therefore, probabilistic approaches are used to consider these uncertainties ...
