Abstract
A fully-integrated 3D surface / subsurface flow model is applied to an exceptionally well characterized reach of Whiteman's Creek in Southern Ontario to determine its ability to predict spatial and temporal variations in groundwater discharge into and directly adjacent to the stream. Detailed surface and subsurface data were collected using ground-penetrating radar (GPR), borehole transects, monitoring wells and mini-piezometers in order to characterize the highly complex nature of the fluvial environment. The GPR data, combined with the borehole logs, defines 3D subsurface stratigraphy on a 30cm-50cm depth scale. Monitoring wells provide water levels, and permeability measurements were obtained using falling-head packer tests. Mini-piezometers were used to measure gradients closely associated with the stream bottom. We will report on the data collected and on the application of the model to the site, and its potential for future use in prediction of locations of salmonids spawning.
