In recent years, water spreading weirs have been implemented on watercourses in West Africa. This study investigates the hydrological impact of water spreading weirs (WSWs) in the semi-arid Wedbila watershed of Burkina Faso, a region challenged by soil degradation and scarce water resources. The study employs an integrated, multidisciplinary approach combining in situ monitoring of surface water levels, soil moisture at multiple depths, and piezometric fluctuations to capture the influence of WSWs on soil water dynamics and aquifer recharge. Comparative analyses between zones impacted by water spreading and control zones provide a robust empirical basis-making this one of the few West African studies to comprehensively combine these measurements in assessing WSW effects on infiltration and groundwater recharge. Results demonstrate that WSWs significantly enhance soil moisture retention near the surface and notable rises in piezometric levels observed during and after flood events. Correlation analysis of monitored parameters indicated that groundwater recharge is dependent on rainfall distribution, surface water levels, and soil properties. Using soil water balance, the annual infiltration calculated in the spreading zone was 568 mm, significantly exceeding that observed outside the spreading zone. Cumulative infiltration during spreading periods accounted for 57 % of annual infiltration. This water spreading weirs positive impact demonstrates, contingent upon spreading duration, topography and soil characteristics. Importantly, the WSWs as a low-cost managed aquifer recharge (MAR) solution suitable for data-poor, semiarid regions like Burkina Faso. By enhancing the landscape's capacity to capture scarce and erratic rainfall, WSWs contribute to climate resilience and agricultural productivity in vulnerable rural communities facing increasing water scarcity due to climate change. They serve as a complementary technique for raising the groundwater level when conditions are favorable in Burkina Faso.
