The knowledge of the distribution of leachate and gas in a municipal landfill is of vital importance to the landfill operators performing improved landfill treatments and for environmental protection and efficient biogas extraction. We have explored the potential of using the velocity fields of seismic S- and P-waves to delineate the wet and...

Nowadays many countries use landfilling for the management of their waste or for treating old landfills. Emissions from landfills can be harmful to the environment and to human health, making the stabilization of landfills a priority for the landfill communities. Estimation of the emission potential for determination of the aftercare period and...

In this study we investigate the application of seismic interferometry (SI) to seismic reflection data recorded over a landfill. Landfills represent strongly heterogeneous subsurfaces making the seismic reflection imaging challenging. We show that SI improves the imaging of high-density areas, which create scattering events in the recorded data....

Leachate and gas are a product of biochemical reactions occurring inside the landfill. Treatment technologies (e.g., recirculation of leachate) are developed to reduce the production of leachate. Imaging the location of the wet and gas pockets inside the landfill can help improve the treatment technologies. Wet pockets occur inside the landfill...

Understanding the processes occurring inside a landfill is important for improving the treatment of landfills. Irrigation and recirculation of leachate are widely used in landfill treatments. Increasing the efficiency of such treatments requires a detailed understanding of the flow inside the landfill. The flow depends largely on the...

The ability to image and quantify the heterogeneity in municipal landfills is crucial for improving the landfill treatment methods, for predicting the behaviour of processes that take place inside the landfills and hence, for estimating the after-care period. Our aim is to image the flow paths inside landfills and to quantify the heterogeneity....

A significant problem with landfills is their aftercare period. A landfill is considered to be safe for the environment only after a relatively long period of time. Until it reaches such a condition, it has to be periodically treated. Not only are treatments very expensive, but they could be dangerous as well; for example, when barriers limiting...

Understanding how sensitive the seismic method is to errors that can occur during a seismic survey or during the processing of the seismic data is of high importance for any exploration geophysical project. Our aim is to image the subsurface of a landfill, which is typically a heterogeneous system due to the presence of numerous scatterers....

Modern sanitary landfills are one the most important final storage solutions for safely storing waste in modern society. Many countries around the world have implemented regulations in order to protect the environment from adverse emissions from the landfills. Generally these regulations require the installation of protective barriers which...

Municipal solid waste landfills are a very complex and heterogeneous systems. The waste in a landfill body is a heterogeneous mixture of a wide range of materials containing high levels of organic matter, high amounts of salts and a wide range of different organic and inorganic substances, such as heavy metals and organic solvents. A range of...
