Title: Delineation of water table using the ground penetrating radar
Authors: Quaye, Evans Kanyi-Koi
Issue Date: 12-Jul-2015
Abstract: This research work is aimed at investigating, determining and delineating the depth to water table and the water saturation level from the surface using the Ground Penetrating Radar (GPR) technique. The survey was conducted at the 55.5 hectare oil palm and citrus plantation portion of the Agriculture Research Station located in the town of Anwomaso which is under the Faculty of Agricultural Science – KNUST. The MALA GPR equipment with 25 MHz Rough Terrain Antenna (RTA) frequency was used for the data collection. GPR data were collected on thirty five profiles of different lengths (100-500 m) at 18 m inter profile spacing in the common offset mode. Results from the survey successfully revealed the average depth to the water table from the land surface to be 30.3 m. The implication of this is that boreholes must be sunk beyond this depth in the saturated zone in order to pump groundwater. It was further revealed that the water table in all cases traced the geometry or topography of the land at various elevations above mean sea level. Subsurface reflectors such as buried objects were also brought to fore. The water table data conform to hydro-geological data within the survey metropolis where most of the boreholes have an average depth of about 35 m.
