## DESCRIPTION

i.eb.evapfr calculates the evaporative fraction after Bastiaanssen 1995. The main implementation follows Alexandridis et al. (2009). The module takes as input the net radiation (see r.sun, i.eb.netrad), soil heat flux (see i.eb.soilheatflux) and sensible heat flux (see i.eb.hsebal01). A flag adds a root zone empirical soil moisture output from the article of Bastiaanssen, et al. (2000).
