Abstract
An intensive ground-penetrating radar (GPR) survey has been conducted over a point-bar of Whiteman’s Creek in Southern Ontario for the purpose of characterizing subsurface stratigraphy for input into a new fully-integrated 3D surface / subsurface flow model. A Sensors and Software pulseEKKO IV system with 100 and 200 MHz antennas was used to collect two sets of overlapping data on a 4m by 4m grid over an area of approximately 7500 square metres. Prominent subsurface features were correlated between GPR profiles. In addition, statistical correlations were performed, resulting in a multi-layered 3D block. Borehole and trench data are used to confirm boundary conditions and conductivities for use within the model. The final conceptual model represents the large-scale features and demonstrates the complexity involved in characterizing fluvial environments. Small-scale stratigraphy at the site will be interpreted more completely in a future study.
