Core Ideas A community effort is needed to move soil modeling forward. Establishing an international consortium key in this respect. There a need better integrate existing knowledge models. Integration of data and models challenge modeling. The remarkable complexity its importance wide range ecosystem services presents major challenges the processes. Although progress has occurred last decades, processes remain disjointed between disciplines or services, with considerable uncertainty...
Soil water content (SWC) plays a key role in partitioning and energy fluxes at the land surface controlling hydrologic such as groundwater recharge. Despite importance of SWC, it is not yet measured an operational way larger scales. The aim this study was to investigate potential wireless sensor network technology for near‐real‐time monitoring SWC field headwater catchment scales using recently developed SoilNet. forest Wüstebach (∼27 ha) instrumented with 150 end devices 600 EC‐5 sensors...
Our understanding of short‐ and long‐term dynamics spatial soil moisture patterns is limited due to measurement constraints. Using new highly detailed data, this research aims examine seasonal event‐scale in the topsoil subsoil small spruce‐covered Wüstebach catchment, Germany. To accomplish this, univariate geo‐statistical analyses were performed for a 1 year long 4‐D data set obtained with wireless sensor network SoilNet. We found large variations topsoil, mostly related meteorological...
Abstract Technological and methodological progress is essential to improve our understanding of fundamental processes in natural engineering sciences. In this paper, we will address the potential new technological advancements soil hydrology move forward water related across a broad range scales. We focus on made quantifying root uptake processes, subsurface lateral flow, deep drainage at field catchment scale, respectively. elaborate value establishing science‐driven network hydrological...
[1] Soil water content is one of the key state variables in soil-vegetation-atmosphere continuum due to its important role exchange and energy at soil surface. A new promising method measure integral field or small catchment scale cosmic-ray probe (CRP). Recent studies CRP measurements have mainly presented results from test sites located very dry areas agricultural fields with sandy soils. In this study, distributed continuous a wireless sensor network (SoilNet) were used investigate...
Core Ideas There has been tremendous progress in GPR as a tool for soil water content determination. Numerous studies have shown the potential of to detect and map SWC. We highlight new possibilities achievements acquisition processing strategies. Quantitative SWC detection hydrological parameter estimation are possible using GPR. encourages other communities embrace Tremendous made with respect ground penetrating radar (GPR) equipment, data acquisition, since establishment determination...

There is increasing interest in the use of multiple measurement types, including indirect (geophysical) methods, to constrain hydrologic interpretations. To date, most examples integrating geophysical measurements hydrology have followed a three‐step, uncoupled inverse approach. This approach begins with independent inversion infer spatial and/or temporal distribution property (e.g., electrical conductivity). The then converted water content) through petrophysical relation. inferred used...
Spectral impedance measurements are receiving increased attention with regard to the characterization of soils, sediments and rocks, particularly in terms internal rock structure, mineralogical composition chemistry fluids contained porous rocks. In fluid-saturated, sedimentary which particular relevance for many hydrological environmental problems, polarization processes that give rise an observed phase shift between input current output voltage signals caused by interaction electrolyte...
We analyze the common surface reflection and full‐wave inversion methods to retrieve soil dielectric permittivity correlated water content from air‐launched ground‐penetrating radar (GPR) measurements. In approach, antenna effects are filtered out raw data in frequency domain, is performed time on a window focused reflection. Synthetic experiments investigate most critical hypotheses which both techniques rely, namely, negligible of electric conductivity ( σ ) layering. range 1–2 GHz we show...
