The impact of climate change on the management and planning of coastal urban areas has become a worldwide issue and has been the subject of several studies in recent decades. Climate change projection in the design phase of urban planning allows building capacity for urban adaptation and avoids future economic costs. Many coastal communities still keep reactive adaptation responses due to a lack of knowledge about how to incorporate this information in planning. In this sense, this paper presents a modelling framework to guide the incorporation of climate projections in the planning and management of coastal areas. The framework was applied in a coastal city of Brazil, where high environmental vulnerability and constantly coastal flooding are observed. The results indicate that there is no significant difference between the emission scenarios, in the short and medium-term, for precipitation projections and runoff peak flow. Extreme rainfall projections give differences up to 21% between the historical series and the projection for 2100. For the sea level projection, the extent of flooded areas induced by the worst emission scenario until the end of the century will reach 10% of the total municipally area (characterized by ecologically sensitive areas). In general, the framework provides preliminary information that can be used to improve spatial planning in a local context. Given the several simplified assumptions, the results should be used with caution, serving as a baseline for future planning efforts in the search for resilient cities.

将气候预测纳入城市基础设施综合规划和管理的框架

气候变化对沿海城市地区管理和规划的影响已成为一个世界性问题,并成为近几十年来多项研究的主题。城市规划设计阶段的气候变化预测有助于建设城市适应能力并避免未来的经济成本。由于缺乏关于如何将这些信息纳入规划的知识,许多沿海社区仍然保持被动的适应反应。从这个意义上说,本文提出了一个建模框架,以指导将气候预测纳入沿海地区的规划和管理。该框架应用于巴西的一个沿海城市,在那里观察到高度的环境脆弱性和持续的沿海洪水。结果表明,排放情景之间没有显着差异,在短期和中期,用于降水预测和径流峰值流量。极端降雨预测给出的历史序列与 2100 年预测之间的差异高达 21%。对于海平面预测,到本世纪末最坏排放情景导致的洪水区范围将达到全市总面积的 10%区(以生态敏感区为特征)。一般而言,该框架提供了可用于改进本地环境中的空间规划的初步信息。考虑到几个简化的假设,应谨慎使用结果,作为未来寻找弹性城市的规划工作的基线。极端降雨预测给出的历史序列与 2100 年预测之间的差异高达 21%。对于海平面预测,到本世纪末最坏排放情景导致的洪水区范围将达到全市总面积的 10%区(以生态敏感区为特征)。一般而言,该框架提供了可用于改进本地环境中的空间规划的初步信息。考虑到几个简化的假设,应谨慎使用结果,作为未来寻找弹性城市的规划工作的基线。极端降雨预测给出的历史序列与 2100 年预测之间的差异高达 21%。对于海平面预测,到本世纪末最坏排放情景导致的洪水区范围将达到全市总面积的 10%区(以生态敏感区为特征)。一般而言,该框架提供了可用于改进本地环境中的空间规划的初步信息。考虑到几个简化的假设,应谨慎使用结果,作为未来寻找弹性城市的规划工作的基线。到本世纪末,由最坏排放情景引起的洪灾面积将达到全市总面积(以生态敏感区为特征)的 10%。一般而言,该框架提供了可用于改进本地环境中的空间规划的初步信息。考虑到几个简化的假设,应谨慎使用结果,作为未来寻找弹性城市的规划工作的基线。到本世纪末,由最坏排放情景引起的洪灾面积将达到全市总面积(以生态敏感区为特征)的 10%。一般而言,该框架提供了可用于改进本地环境中的空间规划的初步信息。考虑到几个简化的假设,应谨慎使用结果,作为未来寻找弹性城市的规划工作的基线。
