Skin layer evaporation to account for small precipitation events—An enhancement to the FAO-56 evaporation model

Allen, Richard G. - In: Agricultural Water Management 99 (2011) 1, pp. 8-18

The FAO-56 soil water evaporation model is a simple ‘slab’ model that has been found to produce good estimates of evaporation from bare soil over a range of conditions due to its adherence to conservation of mass and energy. The simplicity of the model makes it straightforward to apply and...
