Watershed Modelling to Enhance Water Security for the Region of Peel

向消费者提供安全用水是供水商的一个关键特点。** 供水商提供的水必须在水质方面“安全”，这是最重要的问题。这就必然要求 ** 水处理系统积极主动地确保水源的质量是足够的，并且处理 ** 技术对进入处理厂取水口的水的质量做出反应。对于Peel地区的湖泊威胁，有一个湖泊水动力学模型;但是，** 风暴和融雪事件后，由于取水口附近的浊度和藻类增加，** 水处理需要调整。增加浊度和磷的主要来源是由水道从流域输送到湖泊的悬浮固体和营养物质。这项研究将 ** 开发一个流域模型，以估计从信贷 ** 河输送到安大略湖的营养物质负荷，以便优先考虑改造工作。此外，该研究还将提供皮尔地区处理厂附近的信贷河的实时总悬浮固体（TSS）和磷浓度。然后，Peel的Lake模型将把这些信息作为输入，以实时估计靠近进水口的TSS** 浓度，并为工厂经理提供调整处理 ** 操作的机会。

Provision of safe water to consumers is a key feature associated with water purveyors. Water as provided by**water purveyors must be 'safe' in terms of water quality as a paramount concern. This necessarily requires the**water treatment system to be proactive to ensure the quality of the source water is adequate, and the treatment**technologies are responsive to the quality of the water being drawn into the treatment plant intakes.**For Lake-based threats as is the situation for the Region of Peel, there is a lake hydrodynamic model; however,**water treatment needs adjustment as a result of increases in turbidity and algae near the intakes, following**storm and snowmelt events. The primary sources of increased turbidity and phosphorus are the suspended**solids and nutrients delivered to the Lake from watersheds by the water courses. This research will be**developing a watershed model to estimate loadings of nutrients delivered to Lake Ontario from the Credit**River, so that retrofit efforts can be prioritized. As well, the research will provide real-time Total Suspended**Solids (TSS) and phosphorus concentrations from the Credit River close to the Peel Region treatment plants.**This information would then be taken as input by Peel's Lake model to estimate, in real-time, TSS**concentrations close to the intakes and provide the plant manager the opportunity to adjust treatment**operations.
