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，大湖盆地一直在围绕土地使用情况发生巨大变化，首先是从发展前的景观到农业，现在是城市化。这些变化极大地影响了接收水的水质和数量。伊利湖是这种影响的戏剧性例子，持续存在不同形式的藻类和缺氧条件，表明该湖状态不处于健康状态。其他伟大的湖泊，尤其是安大略湖，并没有落后，尤其是随着气候变化的变化。结果，对于来源防水，环境影响，娱乐性问题和经济问题，很明显的关注点是显而易见的。结果导致了巨大的水安全问题。为了促进对安大略湖水质问题的了解，该提案涉及与信用谷保护管理局合作，以开发使用Mike Model平台的能力，以模拟水质，数量和其他与生态系统相关的流程。借助Mike Model平台提供的功能，将有能力评估污染物排放，溢出物，气候变化的影响以及随着进化的影响，城市化压力的影响。这种高级建模能力将有助于研究现有和未来影响的范围，这将影响水体质量。
