Application Possibilities of Different Irrigation Methods in Hofel Plain

Bu araştırmanın temel amacı, İran'ın Güney Batı, Huzistan eyaletinde bulunan Hofel Ovası'nda11533 hektarlık bir alanda bir parametrik bir değerlendirme sistemine dayalı farklı sulama yöntemlerininkarşılaştırılmasıdır. Toprak özellikleri analiz edilip ve değerlendirildiğnde, uygunluk haritaları, UzaktanAlgılama (UA) Teknikleri ve Coğrafi Bilgi Sistemi (CBS) kullanılarak yüzey, yağmurlama ve damlamasulama yöntemleri için üretilmiştir. Elde edilen sonuçlar, yüzey sulama yönteminin çalışma alanının1562.2 ha (% 13.5) için şiddetle tavsiye edildiğini; çalışma alanının 5 989.3 ha (% 51.90) için iseyağmurlama sulama yönteminin son derece verimli ve uygun olduğunu göstermiştir. Sonuçlar, yüzey vedamla sulama yöntemleri yerine yağmurlama sulama sisteminin kullanılmasının Hofel Ovası'nda 7 083ha (% 61.7) alanın tarıma elverişliliğini artıracağını ortaya koymuştur. Buna ek olarak, yüzey veyağmurlama sulama yöntemleri yerine damla sulama sisteminin kullanılmasının Hofel Ovası'nda 4 052.3ha (% 35.1) alanın tarıma elverişliliğini iyileştireceğini göstermiştir. Farklı sulama tekniklerininkarşılaştırılması, yağmurlama ve damlama sulama yöntemlerinin yüzey sulama yöntemlerine göre dahaetkili ve arazi verimliliğini artırmak için daha elverişli olduğunu ortaya koymuştur. Bununla birlikte, bualanda yüzey sulama yöntemleri kullanımının ana sınırlayıcı faktörleri ağırtoprak yapısı, CaCO3, drenajve eğim olarak; yağmurlama sulama yöntemleri kullanımının ana sınırlayıcı faktörlerinin tuzluluk vealkalilik, drenaj ve ağır toprak dokusu; damla sulama yönteminin ana sınırlayıcı faktörlerinin ise tuzlulukve alkalilik, CaCO3 ve ağır toprak yapısı olduğu göz önünde tutulmalıdır.

Hofel Ovası'nda Farklı Sulama Yöntemlerinin Uygulama Olanakları

The main objective of this research was to compare different irrigation methods based upon aparametric evaluation system in an area of 11 533 ha in the Hofel plain located in the KhuzestanProvince, in the South West of Iran. Once the soil properties were analyzed and evaluated, suitabilitymaps were generated for surface, sprinkler and drip irrigation methods using Remote Sensing (RS)Techniques and Geographic Information System (GIS). The obtained results showed that for 1 562.2 ha(13.5 %) of the study area surface irrigation method was highly recommended; whereas for 5 989.3 ha(51.90 %) of the study area a sprinkler irrigation method would provide to be extremely efficient andsuitable. The results demonstrated that by applying sprinkler irrigation instead of surface and dripirrigation methods, the arability of 7 083 ha (61.7 %) in the Hofel Plain will improve. In addition byapplying drip irrigation instead of surface and sprinkler irrigation methods, the land suitability of 4 052.3ha (35.1 %) of this plain will improve. The comparison of the different types of irrigation techniquesrevealed that the sprinkler and drip irrigations methods were more effective and efficient than the surfaceirrigation methods for improving land productivity. It is of note however that the main limiting factors inusing surface irrigation methods in this area were heavy soil texture, CaCO3, drainage and slope.Moreover, the main limiting factors in using sprinkler irrigation methods in this area were heavy soiltexture, drainage, salinity, and alkalinity; the main limiting factors in using drip irrigation methods werethe CaCO3 and heavy soil texture.
