A Simple Correction Term to Model Infiltration in Water‐Repellent Soils

Soil water repellency can substantially alter hydrologic processes, particularly the ability of soils to infiltrate water. Water often changes through time, making it difficult simulate infiltration behaviors water-repellent using standard models. Here, we propose a simple rate-based correction term that starts with value zero at beginning process (t = 0) and asymptotically approaches 1 as time increases, thus simulating decreasing soil time. The be used any model. For this study, selected two-term equation then, two data sets measurements conducted in varying repellency, compared model error versus without added term. reduced error, more repellent soils. At same rate constant parameter introduced new may useful better understand dynamics provide consistent interpretations hydraulic properties
