Material and Methods: In the model, the wetting pattern is simulated as a truncated ellipse. Wetting radius at the soil surface, the maximum wetting depth and width in the soil profile, and the depth of this maximum wetting width from the soil surface were taken into account. The experiments were carried out under uniform profile conditions and on soil samples with a loamy sand texture. The investigation was carried out for different emitter discharges. Results: The wetting radius, maximum wetting depth, and cross-sectional area of the wetting pattern occurring at any time t of the water application period under each emitter discharge are estimated with the determination coefficients of 0.961, 0.947 and 0.995, respectively, by the numerical models developed in this study. The results show that the values of 2D cross-sectional area also increase as the emitter discharge increases. Conclusion: The results of this study indicate that the proposed model defines the overall shape of the wetting pattern and can be used to determine the cross-sectional area of the pattern.}, number={4}, publisher={Ege Üniversitesi}, organization={This study did not receive funding from any organisation.}
