Impact of Temporal Macropore Dynamics on Infiltration: Field Experiments and Model Simulations

Abstract: Macropores greatly affect water and solute transport in soils. Most macropores are of biogenic origin; however, the resulting seasonal dynamics are often neglected. Our study aimed to examine temporal changes in biopore networks and the resulting infiltration patterns. We performed infiltration experiments with Brilliant Blue on pastureland in the Luxembourgian Attert catchment (spring, summer, and autumn 2015). We developed an image-processing scheme to identify and quantify changes in biopores and infiltrat… Show more

“…III, the flux into the main bypass macropore was reduced due to dead‐end macropores. Similar observations were made in the work of Reck et al (2018), who noted a large number of macropores in autumn, but most of the infiltrated water was retained in the soil profile because the macropores ended at the 10‐cm depth.…”

“…The effect of coatings in earthworm burrows (Jarvis, 2007) has so far been neglected due to a lack of experimental references. As also found to be important in a study on dynamic macropore settings using the echoRD model (Reck et al, 2018), a dynamic coating factor is however foreseen to scale the macropore-matrix interface. Although most of the specific references have been drawn with relation to earthworm burrows, the current concept is intended to apply to any kind of macropore.…”
