A priori error analysis for transient problems using Enhanced Velocity approach in the discrete-time setting [PDF]
, 2018 Time discretization along with space discretization is important in the numerical simulation of subsurface flow applications for long run. In this paper, we derive theoretical convergence error estimates in discrete-time setting for transient problems ...

Irrigation and Drainage, EarlyView.ABSTRACT Efficient irrigation scheduling is critical in sandy soils to achieve optimum yield and maximum net benefit with minimum environmental concerns. The Environmental Policy Integrated Climate (EPIC) model was used to study the impacts of autoirrigation of corn on crop yield and soil water balance during 2019–2021 at −300 and −450 kPa for loamy ...

Morphing quantum mechanics and fluid dynamics
, 2003 We investigate the effects of given pressure gradients on hydrodynamic flow equations. We obtain results in terms of implicit solutions and also in the framework of an extra-dimensional formalism involving the diffusion/Schrodinger equation.Comment ...

Irrigation and Drainage, EarlyView.ABSTRACT Flow rates for applying nutrient solutions in hydroponic systems are empirically known, yet uncertainties remain regarding whether brackish water affects the optimal flow rate and, consequently, biomass production and allocation. This study evaluated whether variations in application flow rate affect coriander biomass when brackish water is ...
