大量的时间和财政资源被用于解决流域氮和磷的非点源问题。尽管作出了这些努力，但许多流域的水质没有得到实质性改善。本研究的目的是回顾文献，并调查影响城市和农业地区水道营养水平缺乏改善的关键因素。从学术文献中确定的94项研究中，我们发现，虽然60%的研究发现在流域内实施最佳管理措施（BMPs）后水质有所改善，但这些研究大多是建模研究，而不是实地监测研究。对于那些在实施BMP后无法发现水质改善的研究，缺乏改善的原因是：缺乏对BMP功能的了解，滞后时间，流域中BMP的非最佳放置和分布，实施后BMP失败以及社会政治和经济挑战。我们把这些限制因素称为已知的未知数。我们还承认存在阻碍BMP有效性进一步提高的未知未知因素，并建议机器学习，商业和运营管理领域的方法以及长期收敛研究可以用来解决这些未知的未知因素。
Extensive time and financial resources have been dedicated to address nonpoint sources of nitrogen and phosphorus in watersheds. Despite these efforts, many watersheds have not seen substantial improvement in water quality. The objective of this study is to review the literature and investigate key factors affecting the lack of improvement in nutrient levels in waterways in urban and agricultural regions. From 94 studies identified in the academic literature, we found that although 60% of studies found improvements in water quality after implementation of Best Management Practices (BMPs) within the watershed, these studies were mostly modelling studies rather than field monitoring studies. For studies that were unable to find improvements in water quality after the implementation of BMPs, the lack of improvement was attributed to: lack of knowledge about BMP functioning, lag times, non-optimal placement and distribution of BMPs in the watershed, post-implementation BMP failure, and socio-political and economic challenges. We refer to these limiting factors as known unknowns. We also acknowledge the existence of unknown unknowns that hinder further improvement in BMP effectiveness and suggest that machine learning, approaches from the field of business and operations management, and long-term convergent studies could be used to resolve these unknown unknowns.
