| Abstract | ||||
| Water use efficiency is a research topic of increasing importance, especially in arid lands. The main objective of this work is to apply parametric evaluation techniques for assessing the most suitable irrigation systems in an area of 36 km2 in the south of Bahariya Oasis of the Western Desert in Egypt using GIS. Twelve soil profiles were made to represent the different landforms of the study area. The soil physicochemical analyses were carried out and input in the Geographic Information System to produce suitability maps for irrigation methods. The results indicated that the application of drip irrigation increased the suitability of the land by 37.9% compared to sprinkler irrigation and 47.2% compared to surface irrigation. On the other hand, the application of surface irrigation reduced land suitability by 9.4% compared to sprinkler irrigation and 47.3% compared to drip irrigation. The main Limitations in using surface, and sprinkler irrigation methods are salinity , coarse texture and slope while limitations in using drip irrigation are salinity and coarse texture. Based on these results, applying the drip irrigation method in the study area is efficient and useful in improving land productivity and conservation. | ||||
