2. ANALYSIS OF THE STABILITY OF TAILINGS DAMS IN A SAHELIAN CONTEXT: THE CASE OF THE SANBRADO MINE IN BURKINA FASO

Mrs Fatimata Bintou SAKANDE (Laboratoire Géosciences et Environnement (LaGE))

The SANBRADO mine tailings storage facility has been installed in a river, so we note a habitual presence of water on the south and south-east sides of the tailings storage facility. Also, the existence of power poles on the northeast side of the dam prevented the embankment from being sloped as originally planned.
The aim of this study is to carry out numerical modelling using Geostudio...

1. Contribution to numerical study of combined heat and moisture transfers in porous building multilayer walls made of local material in dry tropical climate

Dr Etienne MALBILA (Ecole Supérieure d'Ingénierie , Université de Fada N'Gourma)

Building materials, being porous media, are subject to heat and moisture transfer, when they are submitted to variables external temperature and relative humidity conditions. The moisture flow can degrade the materials thermal performances and then increase the need of energy to maintain the building interne comfort. In order to make a judicious choice of adapted materials to dry tropical...

5. Development and characterisation of clay nanoparticles for use in removing Cr(VI) from water.

Hadi Hamadoum GORO

Background :
➢ Kaolinite is a lamellar clay with interesting properties due to its layered structure.
structure.
➢ Nano clays have more interesting properties than raw natural clays due to their large
because of their large specific surface areas. These nano clays are intended for use in
purification of wastewater contaminated by heavy metals.
➢ The tanning industry uses large...

6. Estimation of evaporation from the surface energy balance for soil in a tropical environment.

François Dabilgou (LAME)

Abstract. Nowadays, the estimation of the evaporative flow is a challenge for researchers, given its essential place in the energy and hydrological balance and its implication in the processes of effective and efficient management of water resources. Indeed, the precise quantification of the transfer of energy and mass during the evaporation of water from the soil is essential to improve the...

7. Geotechnical characterization of excavated soils for reuse as road embankments and subgrades

Soumaila GANDEMA

In this paper, we present a geotechnical study of excavated soil from a road construction site in Ouagadougou. The excavated material is transported to dumps to make way for lateritic gravel from borrow sites. However, the increasing distance and scarcity of these sites, as well as the costs associated with transport and environmental impacts, are encouraging in-situ soil reuse after thorough...

4. Soil water dynamics under drip irrigation : potential water losses through deep drainage

Siguibnoma Kévin Landry Ouédraogo (Laboratoire de Materiaux et Environnement, Universite Joseph KI-ZERBO, Ouagadougou, Burkina Faso)

Due to water resources scarcity, reasonable water available management has become essential in arid and semi arid regions. Drip irrigation is increasingly used in irrigated agriculture because of its productivity and water savings. However, water may still be lost through deep percolation. In this work, HYDRUS software is used to simulate water movement coupled with heat transport in a...

3. The activity of metal ions impregnated on natural phosphates from Burkina Faso for the synthesis of chalcone in a green solvent.

Jean-baptiste ZOUNGRANA, Dr Brahima SORGHO

The Claisen-Schmidt condensation is one of the most important catalytic reactions for syntheses developed in the 20th century. Generally, this condensation is carried out with or without a toxic solvent in the presence of a catalyst. This research focused on the use of a green solvent (water) for the Claisen-Schmidt condensation reaction, improved by catalysts based on simple natural phosphate...
