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 ...

New Drain Spacing Formulas Using the Variational Iteration Method
ABSTRACT In this study, the drain spacing is computed using the variational iteration method (VIM) to the linearized Boussinesq equation. By applying at most two iterations of the VIM method under three different initial condition scenarios, three equations for drain spacing calculation were derived. These equations predict values of drain spacing that

Software “slide” for sprinkle irrigation lateral line design
Sizing conventional downhill sprinkler lateral lines requires careful consideration, as the pressure distribution profile along the line can take different configurations depending on the slope of the terrain. The objective of this work was to develop a software, called SLIDE, that allows to interactively design of the lateral lines in any slope ...

Optimization of Sprinkling Parameters for Improved Irrigation Quality
Under conditions of water scarcity and climate change, it is crucial to align irrigation intensity with the soil’s infiltration capacity. This study presents analytical modeling of the optimal sprinkling parameters (intensity and duration) taking into account the hydro-physical properties of soils, namely porosity and moisture content.

Drought spatiotemporal propagation and direct driving variables are assessed at multiple time steps with high spatial resolution using various drought indices (SPI, SPEI and SPDI) and entropy based mutual information under an ensemble of climate change projections over Tunisia. ABSTRACT Projecting drought occurrence and spatiotemporal propagation under
