On the concept of ecohydrological separation of flows in ecosystems

\nIn this paper, within the framework of the concept of ecohydrological separation, modeling of changes in transpiration flow velocity in a tree at fluctuations of relative humidity of the environment is carried out with the help of basic equations of fluid mechanics and gas mechanics. In a computational experiment, the result is determined by parameters that have a clear physical meaning and take into account the unique properties of tree pores and the solutions in them. The model can be used to identify the characteristic range for parameter values taking into account the influence of climate, soil composition, tree species and to form databases for research of transpiration processes and the influence of the environment on them.\n
