RETC with hysteresis

Post by j.evaristo@uu.nl » Fri Sep 15, 2023 8:38 am

Hello. Can RETC be used to estimate the vG parameters on soil water retention data with clear hysteresis?

RETC does not consider hysteresis, However, you can obviously analyze separately wetting and driving branches of the retention curve, and get parameters for each of these. J.
