Hello Dr. Du Toit :

Thank you for your very kind message to the DSSAT listserver.

The RWU function is explained on page 50 of the chapter by Dr. Ritchie
entitled "Soil Water Balance and plant water stress," in the book by Tsuji
et al. Understanding Options for Agricultural Production.  The function is
not new and has been used in the models for a long time.

Kind regards,

Gerrit Hoogenboom
