Watershed Modelling to Enhance Water Security for the Region of Peel

向消费者提供安全食水是供水商的主要特点。**供水商所提供的食水必须以水质“安全”为首要考虑。这必然要求**水处理系统积极主动，以确保源水的质量是足够的，并且处理**技术对进入处理厂进水口的水的质量作出反应。**对于以湖泊为基础的威胁，如皮尔地区的情况，有一个湖泊水动力模型；然而，在风暴和融雪事件之后，由于进水口附近的浑浊度和藻类增加，水处理需要调整。浊度和磷增加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的负荷，以便优先考虑改造工作。此外，该研究还将提供实时的总悬浮固体（TSS）和磷浓度，这些浓度来自皮尔地区处理厂附近的Credit河。这些信息将作为皮尔湖模型的输入，用于实时估计进水口附近的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.
