European forests are suffering considerably from the consequences of droughts recent years, and exact reasons influencing factors for this still not fully understood. This study was conducted to characterize changes dynamics soil moisture in a mixed forest northern Bavaria within 1 year. Since electrical resistivity correlates well with water content, we used two-dimensional tomography (ERT) mo...

Catchment drainage area is a basic spatial unit in landscape hydrology within which the authorities estimate water balance and manage resources. The catchment commonly delineated based on surface topography, determined using digital elevation model. Therefore, only flow over implicitly considered. However, substantial portion of rainfall infiltrates percolates through soil profile to groundwate...

Electrical resistivity (ER) is a main parameter in the melting processes of glasses. However, its measurement is difficult at high temperatures. In this study the electrical resistivity of different cordierite glass samples in the molten state was measured in the temperature range of 1100˚C to 1550 ˚C using the two-wire method. It was attempted to decrease the electrical resistivity of the glas...

Knowing the soil moisture distribution in unsaturated zone can improve understanding water flow through and thereby enable calculation of aquifer recharge, which occurs precipitation. One part Zagreb recharge infiltration from In order to observe model precipitation zone, research polygon was constructed at Velika Gorica well field, located southern aquifer, Croatia, where hourly measurements e...

Underground and opencast mining adversely affects the surrounding environment. This process may continue even decades after end of actual mineral extraction. One most significant effects ceased are secondary deformations. Safe, new development post-mining areas requires reliable information on potential deformation risk zones, which be difficult to obtain due a lack necessary data. study aimed ...

Electrical Resistance Tomography (ERT) offers a non-destructive evaluation (NDE) technique that takes advantage of the inherent electrical properties in carbon fiber reinforced polymer (CFRP) composites for internal damage characterization. This paper investigates a method of optimum selection of sensing configurations for delamination detection in thick cross-ply laminates using ERT. Reduction...
