Hydrogeophysical investigation of river-aquifer interaction: A case study of the Bama-ridge shallow aquifer and river Ngada, Dalori, North-eastern Nigeria
Geoelectrical depth soundings were conducted on the same area on the Bama Ridge at different times of the year, covering over three seasons. The surveys were conducted at the beginning of the rainy season and repeated at the end of it. These times corresponds to when the river bed is almost empty of water (June) and when the Ngada River is still flowing and it is at its highest stage (October) respectively. The interpreted results of the study show that the shallow aquifer of the Bama Ridge is in hydraulic connection with the Ngada River. The apparent resistivity curves also indicated that Vertical Electric Sounding (VES) could be used as a preliminary technique to explore possible river-aquifer interaction phenomena in a hydrologic system.
