Impact of compost application rates and depths on soil hydrodynamic properties and irrigation efficiency
Optimal water management in irrigation relies, among other things, on soil properties, which can be modified by agronomic interventions such as composting. It is in this context that the present study was carried out in 2024 at the experimental site of the Institut National de l'Eau to determine…

A remote sensing–based approach to the regionalization of socioeconomic indicators in an agricultural headwater catchment in Northern Benin
The agroecosystems of the rural continuum of the Sudano-Sahelian region of the Volta River Basin are undergoing severe degradation, resulting in serious declines in ecosystem service capacities and weakening community livelihoods, as agriculture remains the primary source of income in the region…

Temporal variability of extreme precipitation in Cotonou: stable climate signal and worsening urban flood impacts
Urban flooding has worsened significantly in Cotonou (major flood events in 2010, 2018, and 2020), yet this deterioration occurs against a backdrop of largely stable extreme precipitation. This study analyses the temporal variability of extreme precipitation indices in Cotonou over 40 years…

Influence of cylindrical obstacle concentration on flow dynamics in channels: a computational approach to optimizing geometric configurations
This study investigates the impact of cylindrical obstacle concentration (C) on flow dynamics in low-slope channels using ANSYS Fluent. Cylinders (D = 12 cm, L = 15 cm) were arranged with varying axial and lateral spacings, producing concentrations from 9 % to 64 %. Simulations under critical flow…

Residual-based hybrid modeling combining GR4J and machine learning for streamflow prediction in data-scarce catchment: case of the Ouémé catchment at Bonou (Benin, West Africa)
Accurate streamflow forecasting is essential for water resource management, yet remains challenging in data-scarce regions. This study develops and evaluates a hybrid modeling framework for the Ouémé River basin (Benin) that combines the conceptual GR4J hydrological model with machine learning (ML)…

Using radiotracers 137Cs and 210Pbex to document climate change in mountain areas through the estimate of soil erosion rates
During the last few decades, a general increase in heavy rainfall events has been documented in many areas of the world. These events have caused changes in soil erosion rates and strongly affected the human activities in mountain areas by reducing the national income obtained from cultivated land…
