Soil Water Retention: Uni-Modal Models of Pore-Size Distribution Neglect Impacts of Soil Management [PDF]

open access: yes, 2018
Most models describing soil water retention imply a uni-modal pore-size distribution (PSD). The uni-modal model presented by van Genuchten (termed vanG) is widely used although double-exponential models (termed Dex) implying a bi-modal PSD may better ...
