原始语种摘要: The different aquifer units within the Lower Orashi River Sub-Basin Southeastern Nigeria were delineated using the Vertical Electrical Sounding (VES) technique. Twenty two (22) VES soundings were carried out using the ABEM SAS 4000 Terrameter. The data generated were analyzed using the Zohdy software which outputted modeled curves in terms of depth and resistivity. Six profiles were taken in the Northeast–Southwest and Northwest–Southeast directions to cover the entire area of study. Four to six geo-electric layers comprising the top soil, clayey sand, dry sandstone, saturated sandstone, shaley sand and sandy shale were delineated with the later usually occurring as the last layer. The third and fourth layers underlying dry sandstone form the aquiferous unit. This unit was found to have...
