AbstractGroundwater and surface water have different characteristics. They are both part of the hydrologic cycle and there are various hydrologic transfers between them. These hydrological processes also influence biogeochemical and biological processes. Groundwater-surface water (GW-SW) interactions are the combination of these processes and their effects. GW-SW interactions generally occur at small scales and are spatially and temporally variable but they can influence flow, chemistry and biology at large scales. Therefore, GW-SW interactions affect many environmental and societal issues related to water quantity, water quality, aquatic ecosystems and watershed management. Science can support management of these issues by determining where and when GW-SW interactions are significant, and what impact they have at larger scales. Partners in the southern Ontario project of the Groundwater Geoscience Program are working to better understand and characterize GW-SW interactions in Southern Ontario through integrated GW-SW modelling, GW-SW interaction framework development and aerial thermal infra-red reconnaissance surveys.
