项目摘要

Low Impact Development technologies (LIDs) are modern stormwater management methods that can improve stormwater quality and reduce stormwater quantity. Bioretention, which involves vegetated depressions in the land surface, is one of these technologies. They has seen widespread implementation but primarily in an ad hoc manner and in regions of mild and warm climates, which are atypical of most climate zones in Canada. The knowledge of the underlying processes to remove pollutants is still lacking and hence, so are the practical tools necessary for predictable bioretention design. In order to equip engineering practitioners with the confidence to use such a technology in Canada, the benefits of bioretention in managing stormwater quantity and quality need to be clearly quantified, and the practical tools for designing bioretention need to be developed. The proposed research project will combine modelling with observations collected on facilities developed at different scales to answer the following questions: i) What are the underlying processes controlling the removal of pollutants (especially nutrients) in bioretention? ii) How can bioretention performance under different hydrologic conditions and different pollutant loadings be compared and evaluated? iii) How can knowledge obtained from bioretention facilities be used to develop predictive tools? iv) How does bioretention perform under varying Canadian climate conditions?  The results from this project will not only provide useful and definitive technical information on bioretention, but the practical, useful tools necessary for bioretention design. Therefore, we propose to: (1) investigate bioretention systems to treat urban stormwater runoff with particular attention paid to the characterization of nutrients, sediment and volume attenuation in terms of their quantity and quality, through field monitoring of various land cover types; (2) examine the impacts of these pullutants on the long term performance of these systems; (3) develop modeling tools for urban storwmater runoff; and (4) develop recommendations using evidence based knowledge for enhancing guidelines and standards associated with urban stormwater management for better protection of our source water and ecosystems in Alberta and beyond.
低影响发展技术(lid)是现代雨水管理方法,可以改善雨水质量和减少雨水量。生物滞留就是其中一种技术,它涉及陆地表面的植被洼地。它们已经得到了广泛的实施,但主要是在气候温和和温暖的地区,这是加拿大大多数气候带的典型情况。对去除污染物的基本过程的了解仍然缺乏,因此,可预测的生物保留设计所必需的实用工具也是如此。为了使工程从业人员有信心在加拿大使用这种技术,必须明确量化生物滞留在管理雨水数量和质量方面的好处,并开发设计生物滞留的实用工具。拟议的研究项目将结合模型和在不同规模的设施上收集的观察结果,以回答以下问题:i)在生物保留中,控制污染物(特别是营养物)去除的潜在过程是什么?ii)如何比较和评价不同水文条件和不同污染物负荷下的生物滞留性能?iii)如何将从生物滞留设施获得的知识用于开发预测工具?iv)在不同的加拿大气候条件下,生物保留率如何表现?该项目的研究结果不仅将为生物保持性提供有用的、明确的技术信息,而且将为生物保持性设计提供实用的、有用的工具。因此,我们建议:(1)通过对不同土地覆盖类型的野外监测,研究处理城市雨水径流的生物滞留系统,特别关注营养物质、沉积物和体积衰减的数量和质量特征;(2)研究这些污染物对这些系统长期性能的影响;(3)开发城市暴雨径流建模工具;(4)利用基于证据的知识提出建议,加强与城市雨水管理相关的指导方针和标准,以更好地保护阿尔伯塔省及其他地区的水源和生态系统。
