Dr. Jennifer Drake's research program will contribute towards the next generation of sustainable stormwater infrastructure. Low impact development (LID) aims to restore and maintain natural flow paths and water balances using blue (detention systems), green (vegetated systems), and grey (conventional minor and major stormwater systems) infrastructure. The realization of LID's promised outcomes - more sustainable and resilient communities - faces substantial challenges, including lack of data, uncertainty in outcomes, and system complexities. The goals of this research program are to learn from past LID successes/failures, improve LID technologies for the unique conditions of Canadian communities, and promote holistic design with performance verification. Urban flooding, a multi-billion-dollar challenge for Canadians, is caused by an increased area of hard surfaces due to urbanization, outdated and undersized stormwater infrastructure, and increased extreme weather associated with climate change. The proportion of the global population exposed to flood risk is growing. Space is limited in urban centres, and it is challenging to meet the ambitious, but necessary, stormwater management objectives of LID (naturalized water balances, flood control, and water quality management) in practice. Experience tells us that decision makers, designers, and other stakeholders are often required to combine the three types of stormwater infrastructure. However, these stakeholders continue to face a scarcity of technical literature, design guidance, and regulatory frameworks to address how these systems can best be integrated.This research program will facilitate sustainability, flood resilience, and climate change adaptation for urban populations, while addressing the problems faced by decision making and design communities. It is original and novel because it is the first to simultaneously address all forms of stormwater infrastructure. The innovative and holistic methodology will advance LID technologies, ensuring that integrated stormwater systems are well designed, constructed, and maintained to address stormwater management objectives both today and in the uncertain future. The proposed program will provide trainees with the critical knowledge and expertise in stormwater management design, operations, and maintenance that is necessary for the next generation of researchers and professionals to address the global climate crisis and increasing risk of urban floods.

詹妮弗·德雷克博士的研究计划将为下一代可持续雨水基础设施做出贡献。低影响开发(LID)旨在使用蓝色(蓄水系统)、绿色(植被系统)和灰色(传统的小型和大型雨水系统)基础设施来恢复和维护自然水流路径和水平衡。LID承诺的结果--更可持续和更具弹性的社区--的实现面临着巨大的挑战，包括缺乏数据、结果的不确定性和系统的复杂性。该研究计划的目标是从过去的LID成功/失败中吸取教训，针对加拿大社区的独特条件改进LID技术，并通过性能验证促进整体设计。对加拿大人来说，城市洪水是一项数十亿美元的挑战，原因是城市化导致坚硬地面面积增加，雨水基础设施陈旧和规模不足，以及与气候变化相关的极端天气增加。全球面临洪灾风险的人口比例正在上升。城市中心的空间有限，在实践中实现LID(归化水平衡、防洪和水质管理)雄心勃勃但必要的雨水管理目标是具有挑战性的。经验告诉我们，决策者、设计师和其他利益相关者通常需要将这三种类型的雨水基础设施结合起来。然而，这些利益相关者仍然面临着技术文献、设计指南和监管框架的匮乏，以解决如何最好地整合这些系统。该研究计划将促进城市人口的可持续性、抗洪能力和气候变化适应，同时解决决策和设计社区面临的问题。它具有原创性和新颖性，因为它是第一个同时解决所有形式的雨水基础设施的方案。创新和全面的方法将推动盖子技术的发展，确保综合雨水系统得到良好的设计、建造和维护，以满足当前和不确定未来的雨水管理目标。拟议的计划将为学员提供雨水管理设计、运营和维护方面的关键知识和专业知识，这是下一代研究人员和专业人员应对全球气候危机和日益增加的城市洪水风险所必需的。
