The sensitivity of transpiration, E, characteristics to areal variations of soil properties is
analyzed. The study is performed by a deterministic model and a statistical-deterministic
model. The core of the models is based on the Penman-Monteith concept. The transpiration
characteristics are investigated in terms of analyzing the change of E versus soil moisture
content, q, relative frequency distribution of E (q), and the algorithms for relating E obtained
for a homogeneous and an inhomogeneous areal distribution of q. The heterogeneity of soil …
