Integrated surface and subsurface hydrological modelling

这个研究项目的目的是开发和改进水资源管理的工具和方法。其动机是为了加拿大人民和生态系统的利益，必须实现水资源，特别是地下水的可持续利用。地下水可持续利用的目标是防止其枯竭和污染。另一个目标是，通过抽水提取地下水必须保持生态系统的完整性，因为地下水流入溪流和河流对在干旱时期保持水流至关重要，它直接影响水生生态系统。为了达到可持续用水的目标，需要计算机模型尽可能准确地模拟集水区尺度上的水循环。该研究项目将通过将沉积过程添加到综合水文模型中，以更严格地表示溪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。一些研究也将集中在集水区污染物的模拟。模型的新功能将是唯一的，并且在任何其他现有模型中都找不到。因此，该研究项目将提供一个独特的计算机模型，这将有助于增加我们对地表水和地下水之间相互作用的理解，并有助于更好地管理水资源。该项目的一个实际成果将是知识的转移，包括为负责水管理的其他科学家和专业人员提供所开发的模型。除了科学方面之外，这项建议的一个关键目标是在水资源的基本和应用方面训练高度合格的人员。项目期间将有2名硕士生和4名博士生积极参与研究并获得学位。一旦他们毕业，这些学生将成为训练有素的专业人员，具备解决水资源紧迫问题所需的先进技能。他们在学习期间接受的培训将使他们能够在学术界、政府或工业界工作，并为健全的水资源管理作出贡献。

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 groundwater extraction by pumping must maintain the integrity of ecosystems because groundwater flow into streams and rivers is vital to maintain flow during drier periods and it directly affects aquatic ecosystems. To reach the objective of sustainable use of water, computer models are required to simulate as accurately as possible the water cycle at the scale of a catchment. This research project will improve the current capabilities of these models by adding sedimentation processes into an integrated hydrologic model to represent more rigorously the exchange of groundwater and surface water in streams. Some research will also focus on the simulation of contaminants in catchments. The new capabilities of the model will be unique and not found in any other existing model. The research project will thus provide a unique computer model that will help increase our understanding of the interaction between surface water and groundwater and will help to better manage 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. During the project, two Master and four Doctoral students will be actively participating in the research and will obtain degrees. 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.
