The objective of this research is to develop and improve tools and methods that are used in the management of our water resources. The motivation comes from the need to achieve the sustainable use of water resources, in particular groundwater, for the benefit of the Canadian population as well as ecosystems. The objective of the sustainable use of groundwater is the prevention of its depletion and its contamination. Another objective is that the use of groundwater must maintain the integrity of ecosystems because groundwater flow into streams and rivers is vital to maintain baseflow and directly affects aquatic ecosystems. To reach the objective of sustainable use of water, computer models must be develop to represent as accurately as possible the water cycle at the scale of an aquifer. This research will improve the current capabilities of these models by adding more components of the hydrologic cycle. The research planned will increase our understanding of the interaction between surface water and groundwater, as well as the impact of soil freezing and thawing on water infiltration. One outcome of the project will be the availability of the models developed for other scientists and professionals that are responsible for water management. In addition to the scientific objective, a key objective of this proposal is to train highly qualified personnel in the fundamental and applied aspects of water resources. To reach this objective, it is proposed to train 3 Master's and 3 Ph.D. students during the project. Once they graduate, these students will be highly-trained professionals with the advanced skills required to address pressing issues in water resources. Their training will allow them to work in either academia, government or industry.
