The objective of this research project is to develop and improve tools and methods for the management of our water resources. The motivation comes from the need to achieve a 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 developed to simulate as accurately as possible the water cycle at the scale of a watershed. This research project will improve the current capabilities of these models by representing more rigorously the exchange of groundwater and surface water in streams, by adding sedimentation processes into an integrated hydrologic model. The capabilities of the model will be unique and not found in any other existing model. The research project will thus generate a unique computer model that will help increase our understanding of the interaction between surface water and groundwater and will help in better managing water resources. One tangible outcome of the project will be the transfer of knowledge, including the availability of the models developed, for other scientists and professionals that are responsible for water management. In addition to the scientific aspects, 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 and 3 Doctoral 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. The training they will receive during their studies will allow them to work in academia, government or industry, and contribute to the sound management of our water resources.

这一研究项目的目标是开发和改进我国水资源管理的工具和方法。其动机来自于需要实现水资源的可持续利用，特别是地下水，以造福加拿大人民和生态系统。地下水可持续利用的目标是防止地下水枯竭和污染。另一个目标是，地下水的使用必须保持生态系统的完整性，因为流入溪流和河流的地下水对维持基流至关重要，并直接影响到水生生态系统。为了达到水的可持续利用的目标，必须开发计算机模型来尽可能准确地模拟流域尺度上的水循环。这一研究项目将通过将沉积过程添加到一个综合水文模型中，更严格地描述河流中地下水和地表水的交换，从而改进这些模型的现有能力。该模型的功能将是独一无二的，在任何其他现有模型中都找不到。因此，该研究项目将产生一种独特的计算机模型，有助于增进我们对地表水和地下水之间相互作用的了解，并有助于更好地管理水资源。该项目的一个具体成果将是为负责水管理的其他科学家和专业人员转让知识，包括提供所开发的模型。除了科学方面，这项建议的一个主要目标是培训水资源基本和应用方面的高素质人员。为实现这一目标，计划在项目期间培养3名硕士和3名博士生。一旦毕业，这些学生将成为训练有素的专业人员，拥有解决水资源紧迫问题所需的高级技能。他们在学习期间接受的培训将使他们能够在学术界、政府或行业工作，并为健全管理我们的水资源做出贡献。
