Mechanics and Modelling of Nonpoint Source Pollution

长期的研究目标是开发环境可持续的非点源污染管理的实用方法，包括基于分水岭的水源保护和养分管理。开发的方法将提供评估分水岭水体健康的手段，量化水体的污染物负荷，确定污染物来源及其对负荷的贡献，并评价改善水质所需的最佳管理做法。这种方法的发展需要更好地了解和描述季节性水文学、流域中产生径流和污染物的地区，以及这些具有排水和土壤、土地利用和地形特征的地区的变异性。这项研究将导致开发季节性可变的P指数，并通过确定径流路径和地表径流和泥沙负荷的主要来源来有效管理和重新设计景观。

The long-term research goals have been to develop practical approaches for environmentally sustainable nonpoint source pollution management, including watershed based source water protection and nutrient management. The developed approaches will provide means to assess the health of water bodies in a watershed, to quantify the pollutant loading to water bodies, to identify pollutant sources and their contributions to loadings and to evaluate best management practices needed for water quality improvement. Development of such approaches require better understanding and description of seasonal hydrology, areas contributing runoff and pollutants in a watershed, and the variability of these areas with tile drainage and soil, land use and topography characteristics. This research will lead to the development of seasonal variable P-Index, and tools for effective management and redesigning of landscape by identifying flow paths and dominant sources of surface runoff and sediment loads.
