Abstract
In the Algerian province of El Oued, south-eastern Algeria, the irrigation system plays a vital role in supporting agricultural production, particularly in oil palm plantations, which have experienced significant expansion in recent decades. The development of irrigation techniques in the region dates back to antiquity, with the Lamasba system, discovered by Émile Masqueray in 1877 in the Belzma plain, being one of the most prominent examples of efficient water resource management. This ancient Roman system, which used precise schedules to distribute water from permanent sources, meticulously determined the quantities and times of water flow, reflecting a high level of social and economic organization at that time. During the French colonial period between 1957 and 1959, the Hoba area in the Righiba commune of El Oued province experienced a remarkable growth in oil palm plantations, with the implementation of advanced irrigation techniques, inspired by the ancient Roman system but modified to suit local conditions. As the project expanded, new challenges arose related to water distribution, particularly in fields far from water sources, leading to the construction of small, taller water towers to improve distribution efficiency. This study analyzes the current irrigation system in the Hoba region, focusing on the technical challenges these systems face, such as obsolete valves and the presence of weeds in the irrigation channels, which slow down the water flow and prolong the irrigation time. The study also examines the use of a new 5-meter-high tower that partially solved the problem of low water flow, while providing additional improvement suggestions to ensure the sustainability of agricultural production in these desert areas. The objective of this study is to offer a comprehensive vision on how to improve irrigation systems to meet the needs of modern agriculture and increase productivity in arid environments.
