The Birni N'Konnihydro-agricultural structures are hydraulic works utilized for agricultural purposes in this region of Niger. They play a pivotal role in the country's economy. In recent years, these hydraulic infrastructures have been subjected to a multitude of degradation factors, both physical and chemical in nature. The physical factors include erosion, sedimentation, and fatigue, while the chemical factors encompass corrosion and pollution. Additionally, biological factors, particularly the impact of vegetation, have also contributed to the deterioration of these structures. Anthropogenic factors, such as overuse, inadequate maintenance, and design flaws, have also played a role in the observed degradation. For this reason, the primary objective of this study is to conduct a diagnostic analysis of the Konni hydraulic structures with the aim of proposing strategies for enhancing their performance and mitigating their deterioration, particularly during periods of low water levels. The approach adopted is that the integration of computational and design models, in conjunction with protection and maintenance measures, can extend the lifespan of the structures. This will undoubtedly lead to an improvement in irrigation efficiency and a reduction in the frequency of food shortages for local residents and economic losses for producers.
