Climate change has significantly altered the historical characteristics of precipitation. Changes in precipitationcharacteristics coupled with trends of rapid urbanization can put pressure on existing urban infrastructure.Untreated sewage often overflows and mixes with runoff when an extreme event occurs. A large amount ofuntreated sewage from cities is thus dumped directly into the river system. This causes adverse socio-economicand environmental impacts in many cities in Canada. The hydrological strategies to alleviate the overall impactshould include both municipal and participatory management in order to make them successful. This projectaims to provide natural and plant-based hydrological participatory management solutions which are inherentlysustainable and low-cost alternatives to current rainwater management practices. To accomplish this, firstrainfall data will be analyzed to understand the characteristics of precipitation such as seasonality, magnitude,frequency, and duration of extreme rainfall. Second, potential stakeholders will be identified and their views onthe management options for mitigation measures will be collected. Third, surplus volume will be estimatedfrom stormwater municipality codes. Finally, different low cost and sustainable rainwater managementalternatives will be selected by using hydrological models in conjunction with stakeholder input. Alternativemanagement selection will be based on socio-economic and environmental considerations. This project willbenefit, to a significant degree, Orbit Engineering in designing economic and sustainable participatoryrainwater management projects for urban areas. This will result in a reduction of construction material andenergy use, and sustainable land use. Moreover, the proposed project will provide a significant contribution tothe science of participatory rainwater management since it focuses directly on the efficiency and sustainabilityof on-site rainwater management through participatory modeling that has not been explored at all to date. Theproject will provide an alternative to costly upgrades of drainage infrastructure and help reduce excessiveuntreated drainage volume from urban areas in Canada.

气候变化显著改变了降水的历史特征。降水特性的变化，再加上快速城市化的趋势，可能会给现有的城市基础设施带来压力。当极端事件发生时，未经处理的污水经常溢出并与径流混合。因此，来自城市的大量未经处理的污水被直接倾倒到河流系统中。这在加拿大的许多城市造成了不利的社会经济和环境影响。缓解总体影响的水文战略应包括市政管理和参与式管理，以使其取得成功。该项目旨在提供天然的和以植物为基础的参与性水文管理解决方案，这些解决方案本身就是可持续和低成本的，可以替代目前的雨水管理做法。为了做到这一点，将分析第一批数据，以了解降水的特征，如季节性、强度、频率和极端降雨的持续时间。第二，将确定潜在的利益攸关方，并收集他们对缓解措施的管理选择的意见。第三，剩余量将根据雨水市政代码进行估计。最后，将结合利益攸关方的意见，利用水文模型选择不同的低成本和可持续的雨水管理备选方案。备选管理选择将基于社会经济和环境考虑。该项目将在很大程度上有利于轨道工程公司为城市地区设计经济和可持续的参与式雨水管理项目。这将减少建筑材料和能源的使用，并可持续地利用土地。此外，拟议的项目将对参与式雨水管理的科学作出重大贡献，因为它直接侧重于通过参与式建模进行现场雨水管理的效率和可持续性，而参与式建模迄今根本没有被探索过。该项目将提供一种替代昂贵的排水基础设施升级的选择，并有助于减少加拿大城市地区过度未经处理的排水量。
