项目摘要

Since the 19th century, the Great Lakes Basin has been experiencing large changes in surrounding land use, first from the pre-development landscape to agriculture, and now, to urbanization. These changes are substantially impacting the water quality and quantity of the receiving waters, both instream and within the Great Lakes. Lake Erie is a dramatic example of such impacts, with constant resurgence of different forms of algae and anoxic conditions, indicating that the lake is not in a healthy state. Other Great Lakes, and in particular, Lake Ontario, are not lagging much behind, especially with the changing climate. As a consequence, major concerns are evident, regarding source water protection, environmental impacts, recreational issues, and economic concerns. The results are causing huge water security issues. To facilitate improved understanding of water quality issues in Lake Ontario, this proposal involves working with Credit Valley Conservation authority, to develop the capability to use the MIKE model platform, to simulate water quality, quantity and other aquatic ecosystem-related processes. With the capabilities provided by the MIKE model platform, the capability will exist to evaluate the spectrum of pollutant discharges, spills, impacts of climate change, and the influence of urbanization pressures, as they evolve. This type of advanced modeling capability will assist research on the spectrum of influences both existing and future, which will impact the quality of the waterbodies.

自19世纪以来，五大湖流域周边土地利用经历了巨大的变化，首先从开发前的景观转向农业，再到如今的城市化。这些变化极大地影响了河流内和五大湖内受纳水域的水质和水量。伊利湖就是此类影响的一个典型例子，不同形式的藻类和缺氧条件不断复活，表明该湖并不处于健康状态。其他五大湖，特别是安大略湖，也并没有落后太多，尤其是在气候变化的情况下。因此，关于水源保护、环境影响、娱乐问题和经济问题的主要担忧是显而易见的。结果造成了巨大的水安全问题。为了促进更好地了解安大略湖的水质问题，该提案涉及与 Credit Valley 保护机构合作，开发使用 MIKE 模型平台的能力，以模拟水质、水量和其他水生生态系统相关过程。借助 MIKE 模型平台提供的功能，将能够评估污染物排放、泄漏、气候变化的影响以及城市化压力的影响。这种先进的建模能力将有助于研究现有和未来的影响范围，这些影响将影响水体的质量。
