Amaç: Bu çalışmanın amacı, damla sulama sistemlerinde oluşan 2 boyutlu ıslatma deseninin analitik olarak tanımlanmasına olanak tanıyan bir model geliştirmektir.
Materyal ve Yöntem: Modelde ıslatma deseni kesik elips olarak simüle edilmiştir. Toprak yüzeyindeki ıslatma yarıçapı, toprak profilindeki maksimum ıslatma derinliği ve genişliği ve bu maksimum ıslatma genişliğinin toprak yüzeyinden itibaren derinliği dikkate alınmıştır. Denemeler, uniform toprak profili koşullarında ve tınlı kum bünyeye sahip toprakta gerçekleştirilmiştir. Araştırma, farklı damlatıcı debilerinde gerçekleştirilmiştir.
Araştırma Bulguları: Bu çalışmada geliştirilen sayısal modeller, farklı damlatıcı debilerinde herhangi bir t anında oluşan ıslatma yarıçapı, maksimum ıslatma derinliği ve ıslak kesit alanını sırasıyla 0.961, 0.947 ve 0.995 belirleme katsayıları ile tahmin etmektedir. Sonuçlar, damlatıcı debisi arttıkça 2B kesit alanının da arttığını göstermektedir.
Sonuç: Bu çalışmanın sonuçları, önerilen modelin ıslatma deseninin genel şeklini tanımladığını ve desenin ıslatma yarıçapı, maksimum ıslatma derinliği ve kesit alanını belirlemek için kullanılabileceğini göstermiştir.

A simulation model for estimating 2D wetting patterns in drip irrigation systems

Öz

Objective: The aim of this study is to develop a model that allows the 2D wetting pattern that occurs in drip irrigation systems to be analytically defined.
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.
