Abstract
Long and short-term variations of local precipitation and streamflow are often reflected in groundwater level fluctuations. In this study, groundwater responses in the Canadian Cordillera are assessed using the best available groundwater, hydrometric and climatic data. Well and stream hydrographs are analyzed using a series of diagnostic tools including time series plots, hysteresis plots, and cross-correlation plots. As might be expected, the seasonal timing of aquifer and streamflow responses requires consideration of the hydro-climatology of the region; rainfall-dominated (pluvial), snowmelt-dominated (nival) or hybrid (mixture of rain and snow). The magnitude and timing of the recharge and discharge responses of the groundwater system were shown to depend on the hydrogeology of the aquifer, specifically its storage and permeability characteristics and whether the system is stream-driven or recharge-driven. These two dominant stream-aquifer system types were defined based on classifying different aquifer types found in the southwest portion of the province. The classification scheme and diagnostic tools have the potential to provide a framework for evaluating the responses of wells in other mountainous regions, as well as the potential consequences of future climate change in these varied hydrogeological and hydro-climatic settings.
