... ABSTRACT: In Northern Bohemia, a new motorway crosses non-engineered landfills of clayey spoil from open cast coal mines. Recent fills are soft, unconsolidated, double porosity medium, originally consisting of lumps of typical dimensions from a few millimetres to a few hundred millimetres...

... ABSTRACT: Soil and groundwater can be easily contaminated by the infiltration of landfill leachate and petroleum hydrocarbons. Leakage of leachate and petroleum hydrocarbons is induced from the damage of liners or underground storage tanks(USTs). Leakage detection system can be effectively...

...1 Instituto Superior TŽcnico, Technical University of Lisbon, Av. Rovisco Pais, Lisbon, Portugal GEOTECHNICAL STUDIES OF WASTE DEPOSITS AND LANDFILLS J. Paulino Pereira1 ABSTRACT Some geotechnical studies of waste landfills in Portugal were used in order to address several questions concerning...

...MODELING SETTLEMENTS IN RANDOMLY HETEROGENEOUS COASTAL-LANDFILLS VIA INVERSE PROBLEM RESOLUTION Vicente Navarro1 ABSTRACT The lack of adequate control in the construction of many coastal landfills results in having an extremely heterogeneous internal structure. So, to determine the settlement...

... ABSTRACT: A database is described that contains results of laboratory measurements of hydraulic conductivity and associated soil properties performed on compacted clay samples from two Belgian landfills. The measurements were conducted on a base liner of one landfill and a capping liner...

... ABSTRACT: Monitoring of the percolation through previously constructed capping layers at a former landfill at Bacton Road, Chandler was carried out to assess their performance under Brisbane climatic conditions. Comparisons of the field percolation with the results of modelling using...

... ABSTRACT: Geotechnical and environmental investigations of buried landfill by drilling or penetration testing are difficult and hazardous. Uncontrolled fill materials can be highly variable, however, landfill is typified by low density, low seismic velocity and high seismic attenuation...

... ABSTRACT: Landfill disposal creates a repository of elements at significantly elevated levels. Entropy dictates that elements at elevated concentrations will be emitted into the surrounding environment. Most regulatory authorities stipulate generic or site specific concentration criteria...

...SETTLEMENT AND CHARACTERISTICS OF WASTE AT A MUNICIPAL SOLID WASTE LANDFILL IN MELBOURNE Samuel T. Yuen1and John R. Styles1 ABSTRACT This paper presents the findings of a settlement investigation conducted at a municipal solid waste landfill in Melbourne. As part of the study, data related...

... changes with depth, these elastic waves are dispersive in nature, which means that they travel at a velocity that is dependent upon frequency (or wavelength). CSWS is a particularly attractive method of investigation for landfill engineering due to the non-intrusive nature of the method that eliminates...

... ABSTRACT: This article presents the results of a study to determine the geomechanical characteristics of waste dumped at landfills, using a large compression-shear experimental device. After determining the physical characteristics of the sample and weight per unit volume of the waste...

... ABSTRACT: Modern sanitary disposal sites, in contrast with old garbage dumps, are based on the concept of assuring minimum environmental impact. Clay is a material nearly unavoidable in the design of landfill bottom liners. However, if mechanical behaviour of clay in contact with water...
