Dissolved organic carbon in a drinking water catchment in the western Ore Mountains, Germany: How much, Where from, When and Why – first insights Open
Increasing concentrations of dissolved organic carbon (DOC) in tributaries threaten the water quality of drinking water reservoirs in Europe and North America. Understanding the key factors influencing DOC dynamics in streams is essential …

Effects of different climatic conditions on soil water storage patterns Open
The soil water storage (SWS) defines the crop productivity of a soil and varies under different climatic conditions. Pattern identification and quantification of these variations in SWS remain difficult due to the non-linear behaviour of S…

A Field Experiment for Tracing Lateral Subsurface Flow in a Post-Glacial Hummocky Arable Soil Landscape Open
Lateral subsurface flow (LSF) is a phenomenon that is widely occurring including the hummocky ground moraine landscape. Due to the heterogeneous structure of the subsurface, transport times of pesticides and nutrients from agricultural are…

Subsurface preferential flow occurrence and relevance in agricultural hillslopes: experimental evidence Open
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 pr…

Exploring the feasibility of using the soil temperature to identify preferential and lateral subsurface flows Open
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 t…

Tracing lateral subsurface flow in layered soils by undisturbed monolith sampling, targeted laboratory experiments, and model‐based analysis Open
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 …

Wavelet Analysis of Soil Water State Variables for Identification of Lateral Subsurface Flow: Lysimeter versus Field Data  Open
<p>Preferential and lateral subsurface flow may be responsible for the accelerated transport of water and solutes in sloping agricultural landscapes; however, the process is difficult to observe. One idea is to compare time series of…

Soil Surface Micro-Topography by Structure-from-Motion Photogrammetry for Monitoring Density and Erosion Dynamics Open
Soil erosion is a major threat to soil fertility, food security and water resources. Besides a quantitative assessment of soil loss, the dynamics of erosion-affected arable soil surfaces still poses challenges regarding field methods and p…
