Modeling of the process of mass transfer by surface and groundwater flows during furrow irrigation of agricultural crops

Abstract

The article presents the results of research on modeling the process of mass transfer by interacting ground and surface water flows, taking into account the migration of moisture in the humidification zone using the dimensionality analysis method, as when solving the problem of mass transfer by interacting ground and surface water flows in the humidification zone, associated with the determination of the mass transfer coefficient, the method of dimension analysis acquires special importance. Based on these considerations, stochastic differential equations of changes in the parameters of the infiltration flow in the humidification zone are derived and a one-dimensional hydraulic model of convective moisture transfer in hydromorphic media caused by irrigation of agricultural crops is obtained.
