Modeling the impact of measured and projected climate and management systems on agricultural fields: Surface runoff, soil moisture, and soil erosion. [PDF]
J Environ QualAbstract As global climate change poses a challenge to crop production, it is imperative to prioritize effective adaptation of agricultural systems based on a scientific understanding of likely impacts. In this study, we applied an integrated watershed modeling framework to examine the impacts of projected climate on runoff, soil moisture, and soil ...

Station hydrologique cotière d'Abidjan de 1966 à 1980 [PDF]
, 1981 In this document the monthly T-S diagrams and the regression lines of the temperature and salinity two weeks mean values have been drawn for 0, 5, 10, 15, 20 and 25 meters of depth. The annual variations of the dynamic height anomaly are represented for every coastal station from 1966 to 1980.

Stations cotieres et station hydrologique cotiere d'Abidjan: annees 1980-1981 [PDF]
, 1982 Beach surface temperature is recorded every morning between 7h30 and 8h00 at each coastal station. On figure 2, 3, 4 and 5 it has been plotted daily variation and mean variation computed on 7, 15 and 30 days basis of sea surface temperature. However it seems that variations of dynamic height anomaly are reflecting more accurately the stages of the ...

Calage et validation de SWAT sur le bassin versant du Bafing (Fleuve Sénégal) en amont de BAFING MAKANA : vers une application à la gestion du barrage de Manantali [PDF]
Proceedings of the International Association of Hydrological Sciences, 2021 En matière de Gestion des Ressources En Eau, il devient de plus en plus nécessaire de remonter à l'information pluviométrique. La modélisation est devenue ainsi un outil incontournable. Les modèles hydrologiques reposent sur le cycle hydrologique.

Global Challenges, Volume 6, Issue 8, August 2022., 2022 The soil and water assessment tool (SWAT) model is used to assess the effects of land‐use change on the hydrological processes of the Lake Tana basin. According to the findings, the SWAT model is essential for effective modeling of the impact of land‐use change on water quality and quantity. Abstract Human activities impact hydrology through changes in

Vadose Zone Journal, Volume 20, Issue 6, November/December 2021., 2021 Abstract Hard rock aquifers (HRAs) in West Africa (WA) are located within a thick regolith layer. The representation of thick tropical regolith in integrated hydrological models lacks consensus on aquifer geometries and parameter ranges. Our main objective was to determine the knowledge requirements on saturated hydraulic conductivity (Ks) to model the
