A new participatory rainwater management framework for urban areas using non-structural measures.

气候变化显著改变了降水的历史特征。降水特征的变化加上快速城市化的趋势会给现有的城市基础设施带来压力。在极端事件发生时，未经处理的污水往往会溢出并与径流混合。大量未经处理的城市污水因此直接排入河流系统。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。减轻总体影响的水文战略应包括市政管理和参与性管理，以使其取得成功。该项目旨在提供自然和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目前雨水管理做法的可持续和低成本替代方案。为了实现这一目标，将对第一次降雨数据进行分析，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。其次，将确定潜在的利益相关者，并收集他们对缓解措施管理方案的意见。第三，剩余水量将根据雨水市政法规进行估计。最后，将利用水文模型结合利益相关者的投入，选择不同的低成本和可持续的雨水管理替代方案。选择替代能源将基于社会经济和环境方面的考虑。该项目将在很大程度上有利于轨道工程设计经济和可持续的参与式城市雨水管理项目。这将导致减少建筑材料和能源的使用，以及可持续的土地使用。此外，拟议的项目将提供一个参与式雨水管理科学的重大贡献，因为它直接关注的效率和可持续性的现场雨水管理，通过参与式建模，还没有在所有的日期探索。该项目将为昂贵的排水基础设施升级提供替代方案，并有助于减少加拿大城市地区未经处理的过多排水量。

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.
