Research ArticleOpen accessIn the author namesESTIMATION OF AQUIFER PARAMETERS IN ERHO, NIGERIA USING THE COOPER-JACOB EVALUATION METHODOchuko Anomohanran, Ruth E. Iserhien-EmekemeThe aim of this study was to determine the aquifer parameters in Erho, Nigeria. This was carried out by drilling three test wells and three observation wells in the study location. Water was pumped from the test wells at a constant rate while the drawdown in the observation wells was determined as a function of time. The data obtained were … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 12 Nov 2014 · 6,910 accessesView PDF Cite

Research ArticleOpen accessIn the author namesDOWNHOLE SEISMIC REFRACTION SURVEY OF WEATHERED LAYER CHARACTERISTICS IN ESCRAVOS, NIGERIAOchuko AnomohanranThe problem of datum correction in seismic surveys and the failures associated with civil engineering structures with specific reference to roads and buildings has been attributed to lack of understanding of the soil structure among others. This is why this survey on downhole seismic refraction was conducted from nine borehole locations in Escravos, Nigeria to determine the weathered layer characteristics … …American Journal of Applied Sciences, Vol. 11, Issue 3 · 30 Dec 2013 · 7,738 accessesView PDF Cite

Research ArticleOpen accessIn the author namesEvaluation of Aquifer Characteristics in Echi, Delta State, Nigeria Using Well Logging and Pumping Test MethodOchuko AnomohanranThis study was carried out to evaluate the aquifer characteristics of groundwater at Echi, Delta State, Nigeria. This was carried out by conducting electrical resistivity and spontaneous potential loggings in a drilled well at the study location. Pumping test using a one kilowatt pumping machine was carried out in the well. The logs were interpreted while the record of the … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 6 Sep 2013 · 6,950 accessesView PDF Cite

Research ArticleOpen accessIn the author namesSeismic Refraction Method: A Technique for Determining the Thickness of Stratified SubstratumOchuko AnomohanranThe seismic refraction survey is a very important geophysical technique used in the investigation of subsurface characteristics. This is why this study was carried out to emphasize the ability of the seismic refraction method in determining the thickness of stratified layers of soil and rock. The results obtained are generalized expressions that relate travel time, offset distance, velocity and thickness … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 7,684 accessesView PDF Cite
