Groundwater movement and availability in crystalline and metamorphosed rocks is
dominated by the secondary porosity generated through fracturing. The distributions of …

Protection and sustainability of water supply wells requires the assessment of vulnerability to
contamination and the delineation of well capture zones. Capture zones, or more generally …

Over the last 50 years, there has been an increased interest in characterizing Precambrian
crystalline rock, such as the Canadian Shield, to investigate the feasibility of deep geologic …

In an aquifer system with complex hydrogeology, mixing of groundwater with different ages
could occur associated with various flow pathways. In this study, we applied different …

Fractured-rock aquifers display spatially and temporally variable hydraulic conductivity
generally attributed to variable fracture intensity and connectivity. Empirical evidence …

ABSTRACT The IAH Commission on Hardrock Hydrogeology (HyRoC) became a significant
feature of the International Association of Hyrogeologists since the early 1990s. It has …

Previous studies of the nutrient budgets of lakes in Precambrian Shield regions have
generally ignored the role of groundwater as a source or sink (influx or efflux) of nutrients …

Exchange fluxes occur when hydrological processes transfer water across the topographic
surface between the groundwater and surface water systems. Many hydrological models are …

In general, the accuracy of numerical simulations is determined by spatial and temporal
discretization levels. In fractured porous media, the time step size is a key factor in …

The effect of future, transient ice sheet movement and permafrost development on transport
of radionuclides from a proposed repository site is investigated using numerical …
