"A model of regional scale groundwater flow is being developed for the Grand River watershed in west central Ontario. This model is one component of a larger effort to determine the potential impacts of climate change on the groundwater resources of the watershed. The central feature of the model is a numerical solution for groundwater flow that is based on a finite difference formulation, and is implemented within a raster GIS setting. Modelling results are used to delineate groundwater catchments, and to determine response functions that may be combined with a time series of groundwater recharge to estimate the variation of groundwater levels and discharge. Preliminary modelling results are presented for the upper Grand River and demonstrate reasonable correspondence with in situ measurements"--Abstract. gccst Groundwater Canada. Environment Canada.
