Coastal flooding is an increasing problem for industries and property owners. Adaptation measures must be implemented by industries that are in flood prone areas and tools to assess flood risk need to be developed to assist companies deciding where to invest. Many coastal communities in Nova Scotia are located at the mouth of major rivers, which make them particularly vulnerable to flooding as sea-level rises. Liverpool, Nova Scotia is one of these communities. Located on the coast where the Mersey River drains into the Atlantic Ocean, Liverpool has areas that have recently seen flooding, possibly from the confluence of overland and storm surge flooding. Parsons Investments Ltd. owns commercial properties in Liverpool which have been damaged due to flooding from the Mersey Estuary in recent years, and are potentially susceptible to combined overland and storm surge flooding. The company is looking to develop tools to investigate mitigation options, and provide a greater understanding of flooding potential for future property development and coastal investments. NSCC's Applied Geomatics Research Group (AGRG) will explore new remote sensing technology (airborne topographic-bathymetric lidar) to assist Parsons Investments in determining the susceptibility of its assets in Liverpool to flooding as well as Liverpool's downtown area, and propose adaptation strategies. Specifically, AGRG will acquire topo-bathymetric lidar for a section of the Mersey River from Liverpool to the outlet where it drains into the Atlantic Ocean to use as input elevation data for a flood model. The new lidar sensor, owned by NSCC, is capable of surveying the river channel bathymetry and Liverpool's land topography, capturing seamless elevation data along the critical land-water boundary. Also, a large scale model for the study site will be constructed and run to investigate past and potential flood events in the future changing climate (ie. sea-level rise). These results will assist Parsons Investments and the other stakeholders in the town and investment community in understanding coastal vulnerability regarding this area and future investment opportunities, and investigate the benefits of using detailed channel bathymetry in flood risk prediction.

沿海洪灾对工业和业主来说是一个日益严重的问题。适应措施必须是 由洪水多发地区的行业实施，需要开发评估洪水风险的工具 协助公司决定在哪里投资。新斯科舍省的许多沿海社区位于河口 这使得它们在海平面上升时特别容易受到洪水的影响。利物浦，新斯科舍省 是这些社区中的一个。位于默西河流入大西洋的海岸上， 利物浦的一些地区最近发生了洪水，可能是陆上和风暴潮的交汇造成的。 洪水泛滥。帕森斯投资有限公司在利物浦拥有商业物业，这些物业因 近几年来自默西河口的洪水，并可能受到陆路和 风暴潮泛滥。该公司正在寻求开发工具来调查缓解选项，并提供 更好地了解未来房地产开发和沿海投资的洪灾潜力。 NSCC的应用地球信息学研究小组(AGRG)将探索新的遥感技术(机载 地形测深激光雷达)，以协助帕森斯投资公司确定其资产在 利物浦对洪灾以及利物浦市中心的影响，并提出适应策略。具体来说， AGRG将购买默西河从利物浦到奥特雷特的一段地形测深激光雷达， 它排入大西洋，用作洪水模型的输入高程数据。新的激光雷达传感器，拥有 由NSCC，能够测量河道水深和利物浦的陆地地形，捕获 沿关键陆地-水域边界的无缝高程数据。此外，研究地点的大型模型将 建造和运行，以调查过去和未来气候变化(即， 海平面上升)。这些结果将有助于帕森斯投资公司和该镇的其他利益相关者 投资界了解这一地区的沿海脆弱性和未来投资 机会，并调查在洪水风险预测中使用详细航道水深测量的好处。
