Geo-electrical data analysis to demarcate groundwater pockets in Ado – Ekiti, southwest, Nigeria
Geo-Electrical Analysis of data obtained from Vertical Electrical Sounding (VES) measurements conducted in Ado-Ekiti has been carried out to demarcate groundwater pockets in the metropolis within the Basement Complex of Southwest, Nigeria. 49 ‘vertical electrical soundings’ were carried out. The layer parameters of resistivity and thickness were determined and used to generate spatial distributions of...

Improving soil surface conditions for enhanced rainwater harvesting on highly permeable soils
The harnessing of runoff water from rainfall over land rather than allowing these waters to run into streams and rivers and eventually lost into the sea is attaining some popularity due to the increasing demand for scarce water resources. Sandy soils, especially in arid and semi-arid regions and along some coastal areas of Ghana (from Aflao to Tema New Town) do not generate sufficient rainwater runoff for storage...

Modelling pan evaporation using mean air temperature and mean pan evaporation relationship in middle south Saurashtra Region
Evaporation and evapotranspiration are the major parameters in the hydrologic cycle and water resources research. Most precipitation is lost in the form of evaporation and evapotranspiration with the percentage varying from region to region globally. Therefore, accurate estimate of evapotranspiration is needed for numerous management activities and its application in rainfall-runoff models. The reference...

Flow system, physical properties and heavy metals concentration of groundwater: A case study of an area within a municipal landfill site
Groundwater within the Olusosun landfill site in Lagos Metropolis was evaluated. Previous research on quality parameters of groundwater in the area made use of equipment of low detection capacity for heavy metals concentrations in water. Also, subsurface flow and significant attenuation of leachate due to horizontal distance between wells and landfill site are yet to be technically elucidated. In the present...

Application of synthetic unit hydrograph methods to construct storm hydrographs
Synthetic unit hydrograph methods were used to generate unit hydrographs for the Awun River Basin in Kwara State, Nigeria. The synthetic methods used were those of Snyder’s, Soil Conservation Service (SCS), and Gray’s. The study watershed has a maximum relief of 183 m with an area of 954 km2 and a slope of 0.15%. The unit hydrograph peak flows for the methods employed ranged from 100.15 to 318.65 m3/s while...
