Abstract
Background: Global climate change, accompanied by recurrent droughts in arid and semi-arid regions, necessitates the development of more effective approaches for regulating soil water regimes. Conventional hydrodynamic methods often perform poorly in soils with thick clay horizons and low permeability, where electrokinetic processes may provide alternative pathways for enhancing water movement. Methods: This study evaluated the parameters of hydrodynamic and electro-osmotic flow in irrigated meadow clay soils of Armenia. Laboratory experiments were conducted under controlled hydrostatic pressure gradients and applied electrical field gradients to characterize filtration behaviour and electro-osmotic response. Result: A strong curvilinear relationship was observed between filtration rate and pressure gradient (R = 0.983), indicating plastic-viscous behaviour of the soil solution. A similar curvilinear dependence was identified between the electro-osmotic coefficient and electrical field gradient (R = 0.884). Electro-osmotic effects substantially increased the water permeability when the electrical field strength exceeded 2.57 V cm-1. These findings demonstrated the potential of electro-osmotic phenomena to enhance water movement in heavy clay soils, offering promising applications for soil-water management under changing climatic conditions.
