Mechanics and Modelling of Nonpoint Source Pollution

长期研究目标是开发环境可持续的非点源污染控制的实用方法，包括基于流域的水源保护和养分管理。这种方法的发展；粮食安全、环境可持续性、土壤复原力、可持续粮食生产和未来能力建设所需；将提供评估水管理做法对流域内水体健康的影响的手段。制定这种方法还需要更好地了解和描述季节性水文、其对水流模式的影响以及所采用的最佳管理做法对养分负荷的影响。本研究的重点是量化由于气候变化导致的河流流量状况的变化，开发一种简单易用的方法来应用最佳管理实践，并开发一种创新的方法来评估结构和非结构最佳管理实践的性能，以控制和改善安大略省独特的季节性气候条件下的河流水质。这种方法将有助于开发有效管理农业土地利用活动引起的沉积物和营养物非点源污染的工具。

The long-term research goals have been to develop practical approaches for environmentally sustainable nonpoint source pollution control, including watershed based source water protection and nutrient management. Development of such approach; needed for food security, environmental sustainability, soil resilience for sustainable food production and for future capacity building; will provide means to assess the effect of water management practices on the health of the water bodies in a watershed. Development of such approach also requires better understanding and description of seasonal hydrology, its impact on stream flow pattern and the impact of adopted best management practice on nutrients loads. This research focuses on the quantification of the changes in the stream flow regimes due to climate change, development of a simple and easily useable approach for the application of best management practices, and the development of an innovative approach to evaluate the performance of structural and non-structural best management practices to control and improve stream water quality in unique Ontario seasonal climatic conditions,. This approach will lead to the development of tools for effective management of sediment and nutrient nonpoint source pollution due to agricultural land use activities.
