Primary data obtained covering water resources, access, capacity, uses, and environment were collected using closed-ended questionnaires. Al...

Study region: Osun Drainage Basin, Nigeria. Study focus: Estimating spatial and temporal patterns of recharge is important for sustainable groundwater resources management. This is especially true for data poor regions, such as the Basement Complex in Nigeria, which has shallow aquifers, a proliferation of wells and no efficient groundwater monito...

Groundwater under Basement Complex areas of southern Kebbi has been characterized in order to determine its suitability for drinking and irrigation use. Water samples were drawn from shallow groundwater (hand-dug shallow wells < 5 m) and deep groundwater (boreholes > 40 m). Physical parameters (i.e., temperature, TDS, pH, and EC), were determined i...

Osun drainage basin is one of the regions in Nigeria experiencing increasing population growth and rapid urbanization; and about 70% of the inhabitants rely on shallow groundwater resources of the region. Change in land use/land cover is one of the significant factors controlling regional hydrology and groundwater resources, thus the continuous cha...

The knowledge of spatial pattern of groundwater quality is important to ensure a holistic approach to the management of the resource quality status in space and time. Thus a sample each of underground water was collected from each of the selected 5 rural communities in each of the selected 25 out of the 33 LGAs in Oyo State for the purpose of quali...

. In Basement Complex rocks where rainfall is seasonal, water provision in dry season depends on regolith aquifer. For effective exploitation of groundwater resources, it is reasonable that geophysical investigation be conducted before development of well. In many instances, geophysical surveys may be expensive or nonexistent. Hence, there is a nee...

Physical availability of water resources is beneficial to man when it is readily accessible. Oyo State is noted for abundant surface water and appreciable groundwater resources in its pockets of regolith aquifers; as it has about eight months of rainy season and a relatively deep weathered regolith. In spite of this, cases of water associated disea...

Groundwater fluctuation is an important phenomenon in water supply within semi-arid regions. Sokoto state has a dry season of 8 months and rainy season of 4 months; this has a profound impact on groundwater level. This study examines groundwater fluctuation within Sokoto metropolis. Groundwater levels in selected shallow wells were monitored after...

Nigeria electricity supply is largely irregular and epileptic. An insight into reservoir management will assist in alleviating this problem. This paper examines the contribution of 10 reservoir element...

This paper examines the need for regional cooperation in water resources management in Africa. The earth is a water planet made up of 70% water, but the crucial fact is that freshwater constitutes only 3%, 99% of which is locked in polar icecaps, glaciers and far too deep underground, leaving humanity with only 0.3% with which to quench its ever in...
