ZOOPLANKTON SPECIES AS INDICATORS OF HYDROLOGICAL VARIATIONS IN SOUTH-SAHARAN RESERVOIRS, BURKINA FASO
Adama Ouéda, Idrissa Ouédraogo, Ilassa Ouédraogo, Frederic Zongo, Magloire Boungou, Wendengoudi Guenda and Gustave B. Kabré
Cette étude contribue à la connaissance des écosystèmes aquatiques semi-arides tropicaux. Il visait à mettre en évidence les espèces de zooplancton qui peuvent être utilisées comme indicateur de la pression provenant des changements saisonniers du régime hydrique. Le zooplancton a été collecté à l'aide d'un filet à plancton (mailles : 100 μm)(...)

Water flow in soil at small water contents: a simple approach to estimate the relative hydraulic conductivity in sandy soil
M. B. Kebré, F. Cherblanc, F. Ouédraogo, F. Jamin, B. Naon, F. Zougmoré & J.-C. Bénet
Unsaturated soil hydraulic properties are key properties in the fields of soil science and civil engineering. Because of their strong dependence on water content, there are considerable experimental and numerical difficulties in their determination, specifically in the dry range. This situation is encountered regularly in arid and semi-arid re(...)

Effect of post-treatment conditions on the inactivation of helminth eggs (Ascaris suum) after the composting process
DARIMANI Hamidatu S., ITO Ryusei, MAIGA Ynoussa, SOU Mariam, FUNAMIZU Naoyuki, MAIGA Amadou Hama
Safe and appropriate disposal of human waste is a basic requirement for sanitation and protection of public health. For proper sanitation and nutrient recovery, it is necessary to ensure effective treatment methods to complete pathogen destruction in excreta prior to reuse. Composting toilets convert faeces to a reusable resource such as ferti(...)

Dans cette étude, la dynamique de l’eau (liquide et vapeur) couplée avec la chaleur en milieu non-saturé est simulée en utilisant le code HYDRUS-1D pour un sol sableux d'une zone semi-aride du Burkina Faso. Un profil de sol assimilable à une colonne de sol sans végétation de profondeur 0,3 m est considéré dans ce travail. Cette étude a permis(...)

SUITABILITY OF GROUNDWATER AND SURFACE WATER FOR DRINKING AND IRRIGATION PURPOSE IN ZIO RIVER BASIN (TOGO).
TAMPO L., GNAZOU D.T.M., KODOM T. , OUEDA A. & BAWA L.M.
Zio River basin plays a particular importance as a potential water resource for irrigation, drinking and for other various purposes relating to socioeconomic activities. These socioeconomic activities considerably change water quality and quantity in this basin. An investigation was carried out by collecting 52 groundwater samples and 168 surf(...)

Greywater Treatment by High Rate Algal Pond under Sahelian Conditions for Reuse in Irrigation
MAIGA Ynoussa, TAKAHASHI Masahiro, SOMDA Thimotée Yirbour Kpangnane, MAIGA Amadou Hama
High Rate Algal Pond (HRAP) was constructed and operated using a mixer device to investigate its capability in treating greywater for reuse in gardening. Physico-chemical and microbiological parameters were monitored. With a hydraulic retention time of 7.5 days and a solid retention time of 20 days, the average removal efficiencies (ARE) were(...)

Zio River catchment drains many cities that it receives waste, domestic and industrial effluents and its waters used to supply drinking water from downstream to upstream. Some schools use it in school canteens without treatment. Meanwhile, no study on tools of water resources management is done in this basin and whole of Togo. To fill this gap(...)
