Studying the impact of global change on water resources is essential for the West African Sahel (WAS), which is known for its fragility. In the Sahelian part of the Nakanbé watershed, located in Burkina Faso, the impact study indicated that environmental change and its interactions were the main drivers of runoff change over the period 1965-1994. Our results show that appropriate environmental management strategies could contribute to sustainable land and water resources management in the WAS.

This research aims to evaluate the feasibility of using multiple rainfall-runoff hydrologic models Génie Rural à 4, 5, 6 paramètres Journalier (GR4J, GR5J, and GR6J) in the Upper Benue River (UBR) in Northern Cameroon. By using the Michel's calibration algorithm, we found that the composite criterion is the most sustainable objective function for model optimization. An honest evaluation empirically proves that the GR6J model performs better than the other two models follow by GR5J.

The results showed that there is an variability in the spatial distribution of extreme indices with an upward and downward trend of dry and wet rainfall periods in West Africa in both historical and projected periods. Thus, the results revealed that the spatio- temporal variability of extreme rainfall can have repercussions on the hydrological functioning of watersheds, water availability and water-dependent activities.

Hydropower (HP) is the 2nd source of energy in Côte d'Ivoire. However water resource for HP is threatened by climate change (CC). Therefore the hydro potential and production are impacted. This study investigates the impacts of future CC in the White Bandama watershed using hydrological modelling coupled with GIS analysis. It emerges that in the future an upward trend in flows will be recorded. This could contribute to the siltation of dams and an increase in the risk of flooding in the basin.

Rainfall causes material damage and human losses in Abidjan, Côte d'Ivoire, every year. This study shows that the period of the 60 wettest days of the long rainy season is more exposed to the risk of flooding than the rest of the year because the rains are more spatially extensive and heavier. The increase in the number of floods in recent years is probably due to the recovery of rainfall after the drought of the 80s associated with the sharp increase in urbanization of the District.

In 2011, the XVI World Meteorological Congress urged Members to make every effort to prevent the deterioration of climate-relevant data and to make these data available to support climate change analyses and relevant climate services. In response to the WMO call, we used the NUNIEAU software which allows the digitization of different types of paper documents by automatic recognition. This software has been used on rainfall pluviograms in Burkina Faso and Côte d'Ivoire.

The Republic of Djibouti is a small country in the Horn of Africa and as with most regions of Africa, rain gauges are sparse. This study aims to compare at different time steps (annual, monthly, and daily) 15 rainfall estimation products (P-datasets) to 5 reference ground-based rainfall stations, over the period of 1980–1990. To classify the reliability of these products, several metrics were considered, the Kling Gupta Efficiency (KGE) and the Heidle Skills Scores (HSS at daily time step).

The objective is to assess the causes of exceptional floods in the Ouémé basin using the HEC-RAS model. The results of the calculation made it possible to characterize: the losses and damage due to human settlement on the banks and agricultural production in the flood zone, the flooded extent and the height of submersion depend on the return period, most of the Flood waters converge towards the west of the basin (low risk) and towards the east around the Damè-Wogon depression (high risk).

Floods are natural disasters that widely affect people, goods, and ecosystems. Some efforts have been made in predicting floods at a short-term range. However, the usefulness of flood prediction increases as the time lead increases. This work investigated covariates useful for flood prediction several months ahead. Very good relationships were found between flood discharge and some climate indexes which could serve as a basis for seasonal flood forecasting in West Africa.

This study addresses the importance of integrating the effect of land use on soil infiltration rate into land use change impact modeling. Based on field measurements; soil parameterization is computed in a hydrological model using a refined soil map integrating land use change impact of soil infiltration rate and a classic soil map not considering this interaction. The results show that integrating land use related effects on soil properties renders LULC change scenarios more plausible.

The objective of this article is to assess recent trends of hydroclimatic quantities in Ogooue basin in the context of climate change. For this, the rainfall and discharges data of this basin were analyzed using the Pettitt test. The results of this study reveal a statistically significant decrease in runoff that the Pettitt test situates in 1972–73, but nothing like that for rainfall at this same time scale.

La sécheresse observée en Afrique tropicale vers la fin des années 1960, a également affecté le bassin de la Bénoué en Afrique centrale, avec une persistance remarquable qui s’est répercutée sur les écoulements. Les ruptures à la baisse ont été mises en évidence dans les séries hydropluviométriques de ce bassin au pas de temps annuel en 1970–71 (pluies) et 1971–72 (débits). Les déficits associés à cette rupture sont de −2,9 % pour les pluies et −14,2 % pour les débits.

This study aims to assess the potential impacts of climate change on hydropower potential of the Lagdo dam. The results reveal that under global warming, the hydropower potential of the dam will decrease which is the result of the reduced precipitation and increase of PET, thus decrease in streamflow in the basin. This result will be take into account for future development planning in the basin.

Le comblement et l’eutrophisation des retenues d’eau constituent des contraintes majeures pour les usages qu’en font les populations riveraines. L’étude bathymétrique a révélé une diminution moyenne de 0,116 m/an. Ce comblement s’explique par l’érosion, la dégradation du couvert végétal et le surpâturage. Les mesures directes de la qualité physique : le pH, la température et l’oxygène dissous ont permis d’évaluer le risque d’eutrophisation. Les eaux sont dans un état eutrophe.

This dataset provides a set of hydrometric indices for about 1500 stations across Africa with daily discharge data. These indices represent mean flow characteristics and extremes (low flows and floods), allowing us to study the long-term evolution of hydrology in Africa and support the modeling efforts that aim at reducing the vulnerability of African countries to hydro-climatic variability.

We relate land cover (savanna forest and agriculture) to evaporation in Burkina Faso, west Africa. We observe more evaporation and temperature movement over the savanna forest in the headwater area relative to the agricultural section of the watershed. We find that the fraction of available energy converted to evaporation relates to vegetation cover and soil moisture. From the results, evaporation can be calculated where ground-based measurements are lacking, frequently the case across Africa.

However, the soil salinity issue is significant because urine and/or greywater, which are potential salt sources. There is very limited information on soil salinity and sodicity from greywater in conjunction with urine/compost. These products can be reused as a nutrient source and water for food production, provided that soil salinity is monitored.

Short summary
Runoff simulation is complex in poorly gauged and data-scarce hydrosystems of the West African Sahel. The results of this study showed that multi-sites calibration without nested sub-catchments is the best modelling scheme for capturing the hydrological response of the Sahelian catchments. This approach could therefore be applied to obtain regionalized parameter values for the West African Sahel region from small catchments distributed across all climatic zones.
