Abstract The effects of drought on tree mortality at forest stands are not completely understood. For assessing their water supply, knowledge the small-scale distribution soil moisture as well its temporal changes is a key issue in an era climate change. However, traditional methods like taking samples or installing data loggers solely collect parameters single point small volume. Electrical re...

8 A geoelectrical investigation of a slow moving earth slide-earth flow in Lower Jurassic Lias Group 9 rocks of the Cleveland basin, UK, is described. These mudrock slopes are particularly prone to failure 10 and are a major source of lowland landslides in the UK, but few attempts have been made to 11 spatially or volumetrically characterise the subsurface form of these slides. The primary aim ...

introduction: occurrence of landslides depends on several factors such as the composition and structure of earth materials, rainfall level, temperature, groundwater regime and cover crops. landslides are a main natural hazard in iran, because of its special geological conditions and its mountainous active tectonic regime. linear civil structures, such as roads, highways and railways, face serio...

Landfill leachate recirculation is applied to manage the landfill as a bioreactor enhance biogas production, limiting impact due greenhouse gas emissions and optimizing energy recovery from biogas. This study deals with geophysical monitoring of within waste pretreated landfill. For this aim, electrical resistivity tomography (ERT) was adopted, detecting main distribution moisture both through ...

Electrical resistivity tomography (ERT) is a well-known geophysical method applied to geological, hydrogeological and geoenvironmental research. To date, 2D ERT still used much more than 3D ERT, thanks its greater immediacy, survey speed lower complexity in processing inversion. However, the assumption of two-dimensionality underground structures can mean that effects on sometimes lead gross er...

Moraine-dammed lakes at debris-covered glaciers are becoming increasingly common and pose significant outburst flood hazards if the dam is breached. While moraine subsurface structure and internal processes are likely to influence dam stability, only few sites have so far been investigated. We conducted electrical resistivity tomography (ERT) surveys at two sites on the terminal moraine complex...
