Identification of leachate infiltration and its flow pathway in landfill by means of electrical resistivity tomography (ERT)

open access: yesEnvironmental Monitoring and Assessment, 2020
Sanitary landfills are a well-planned engineering work for final disposal of municipal solid waste in order to minimize the environmental impacts in soil and groundwater. Therefore, several control systems are installed such as liners and leachate and biogas collectors.

Electrical Resistivity Tomography for the 2D and 3D Investigation of Pingos and Permafrost Mounds in Northern Canada's Mountain and Coastland Areas

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Pingos and related permafrost mounds are widespread periglacial landforms in Arctic environments that are ice‐rich on the one hand and contain taliks on the other, making them vulnerable to climate change. So far, the interior, geophysical characteristics, and distribution of ground ice within these dome‐ or cone‐shaped features have not been ...

Within‐tree spatial heterogeneity of sap flow velocities and wood properties and its effect on the uncertainty of tree level sap flux estimates

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
As forests are important for biodiversity and recreation and provide vital resources globally, it is essential that their health can be accurately monitored, for example, by using sap flow probes to measure tree water uptake. We investigated whether sap flow measurements might differ at various locations within the same tree due to variation in wood ...

Dissolution-enlarged fractures imaging using electrical resistivity tomography (ERT) [PDF]

open access: yes, 2017
In recent years the electrical imaging techniques have been largely applied to geotechnical and environmental investigations. These techniques have proven to be the best geophysical methods for site investigations in karst terrain, particularly when the ...

Joint seismic/electrical effective medium modelling of hydrate-bearing marine sediments and an application to the Vancouver Island margin [PDF]

open access: yes, 2008
Remote determination of the hydrate content of marine sediments remains a challenging problem.In the absence of boreholes, the most commonly used approach involves the measurement of Pwavevelocities from seismic experiments.

PRECARIZED AGEING‐IN‐PERIFERIA: Low‐Income Older Adults in a Transforming Neighbourhood

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract In this article we investigate how intersecting forms of precarity shape the everyday practices of ageing‐in‐place developed by low‐income older adults in Via Milano, a historically segregated yet rapidly transforming neighbourhood in Brescia, northern Italy. We draw on qualitative and ethnographic research to examine how diverse urban changes—
