Heterogeneous small-scale high-contrast layers and spatial variabilities of soil properties
can have a large impact on flow and transport processes in the critical zone. Because their …

Soil moisture is widely recognized as a key parameter in the mass and energy balance
between the land surface and the atmosphere and, hence, the potential societal benefits of …

Core Ideas There has been tremendous progress in GPR as a tool for soil water content
determination. Numerous studies have shown the potential of GPR to detect and map SWC …

In this paper, we review the state of the art of characterizing and analyzing spatio-temporal
dynamics of soil moisture content at the field scale. We discuss measurement techniques …

Recent advances in sensor technologies, field methodologies, numerical modeling, and
inversion approaches have contributed to unprecedented imaging of hydrogeological …

Ground penetrating radar (GPR) is a high-resolution technique widely used in shallow
groundwater prospecting. This makes GPR ideal to characterize the hydrogeological …

Probabilistically formulated inverse problems can be solved using Monte Carlo-based
sampling methods. In principle, both advanced prior information, based on for example …

Limited knowledge about the spatial distribution of aquifer properties typically constrains our
ability to predict subsurface flow and transport. Here we investigate the value of using high …

Spatially highly resolved map** of aquifer heterogeneities is critical for the accurate
prediction of groundwater flow and contaminant transport. Here, we demonstrate the value …
