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.

长期研究目标是开发用于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防水和营养管理。开发的方法将提供评估流域中水体健康的方法，以量化对水体的污染物负荷，以识别污染物来源及其对负载的贡献，并评估水质改善所需的最佳管理实践。 这种方法的开发需要更好地理解和描述季节性水文学，促进流域中径流和污染物的区域，以及这些区域具有瓷砖排水和土壤，土地利用和地形特征的区域的可变性。这项研究将导致季节性可变p索引的发展，以及通过识别流动路径和占主导地位的表面径流和沉积物负载来源来有效管理和重新设计景观的工具。
