Subsurface preferential flow occurrence and relevance in agricultural hillslopes: experimental evidence
Autor: Horst Gerke, Annelie Ehrhardt, Vilim Filipović
Preferential flow (PF) has long been discussed as potential cause for unintended contamination of ground and surface waters with agrochemicals. In agricultural soil landscapes, especially along hillslopes, the mostly vertically-directed preferential

Characterization of macropore-matrix mass transfer parameters in two-domain preferential flow models
Autor: Horst Gerke
The macropore-matrix mass transfer of water and solutes is an important aspect of non-equilibrium-type of preferential flow in structured soils. For a representative soil volume, effective mass transfer parameters depend on heterogeneous local proper

Tracing lateral subsurface flow in layered soils by undisturbed monolith sampling, targeted laboratory experiments, and model‐based analysis
Autor: Horst Gerke, Hans-Jörg Vogel, Kristian Berger, Vilim Filipović, Thomas Wöhling, Annelie Ehrhardt
Publikováno v: Vadose zone journal, 21(4):e20206
Lateral subsurface flow (LSF) is a phenomenon frequently occurring in the field induced by local water saturation along horizon boundaries under nonequilibrium conditions. However, observations of LSF in undisturbed soils under controlled irrigation

Effects of climate change on the nitrogen balance of a grassland ecosystem
Autor: Thomas Puetz, Mona Giraud, Jannis Groh, Horst Gerke, Nicolas Brueggemann
Grassland is one of the most abundant biomes in the world and important for a variety of ecosystem services. Global climate change is causing a significant increase in temperature and a change in the seasonal distribution of precipitation. The result

Exploring the feasibility of using the soil temperature to identify preferential and lateral subsurface flows
Autor: Horst Gerke, Annelie Ehrhardt
Soil temperature can be influenced by rapidly infiltrating water. Deviations from a uniform soil heat distribution could result from vertical preferential flow (VPF) and lateral subsurface flow (LSF) events. The objective was to identify the effect o

Same soil - different climate: crop model inter-comparison with lysimeter data of translocated monoliths
Autor: Horst Gerke
Crop model inter-comparisons have mostly been carried out to test the predictive ability under the past range of climatic conditions and for soils of the same site. Unknown is, however, the ability of individual crop models to predict effects of chan

The fate of eroded soil organic carbon (SOC) after deposition is a large uncertainty in assessing the impact of soil erosion on C budgets. Globally, large amounts of SOC are transported by erosion and a substantial part is transferred into adjacent i

The potential fate of eroded soil organic carbon (SOC) after deposition is key to understand carbon cycling in eroding landscapes. Globally, large quantities of sediments and SOC are redistributed by soil erosion on agricul-tural land, particularly a

A dual-permeability approach was extended to describe preferential water flow and solute transport in shrinking soils. In the approach, the soil is treated as a dual-permeability bulk porous medium consisting of dynamic interacting matrix and fractur
