Impact of future environmental conditions on flood protection and transportation soil slope infrastructure

几乎每天都有全球新闻报道地球上的一些地区正在经历或从极端天气条件中恢复过来。在许多情况下，这些极端天气条件导致或促成某种形式的自然灾害。近年来，加拿大经历了许多自然灾害，如1997年的红河洪水和1996年魁北克省的萨格奈洪水。在这些极端事件中，防洪系统的作用是将事件的影响降到最低，运输系统通过部署资源和疏散市民来保护我们的社区。许多人认为，极端天气事件的频率和强度正在增加。全球变暖和气候变化经常被认为是极端天气事件增加的可能原因。尽管对这些变化的起源存在相当大的分歧，但越来越多的人认为，气候变化正在以某种形式发生，工程师在设计时需要考虑到这一点，以确保我们的防洪和交通基础设施为未来的情况做好准备。该提案将开发工具来测量马尼托巴省两个地点由当地天气条件引起的湿度运动。将根据两个地点的测量结果制定和校准一个数值模型。该数值模型将用于预测所提出的气候变化模型对防洪和交通土坡基础设施的影响。利用预测结果，将开发一个决策支持工具，以帮助规划者和政府机构制定政策，根据极端天气事件期间可接受的风险水平，升级防洪和交通基础设施。这将有助于确保公共资金的最佳支出，以准备我们的防洪和交通基础设施，以应对未来环境设计条件的潜在变化。

Almost daily global news reports some area of the planet that is experiencing or recovering from extreme weather conditions.  In many cases these extreme weather conditions lead to or contribute to some form of natural disaster.  Canada has experienced its share of natural disasters in recent years such as the Red River Flood of 1997 and the 1996 Saguenay Flood in Quebec.  During these extreme events flood protection systems acted to minimize impacts of the events and transportation systems were essential for operations to protect our communities through deployment of resources and evacuation of citizens.Many argue that the frequency and magnitude of extreme weather events is increasing.  Global warming and climate change have often been identified as possible causes to the increase in extreme weather events.  Though there is considerable disagreement regarding the origin of these changes, there is growing agreement that climate change is occurring in some form and needs to be considered by engineers in design to ensure our flood protection and transportation infrastructure are prepared for future conditions.This proposal will develop tools to measure moisture movements at two sites in Manitoba caused by the local weather conditions.  A numerical model will be developed and calibrated based on the measurements from the two sites.  The numerical model will be used predict the impact of proposed climate change models on flood protection and transportation soil slope infrastructure.  Using the results of the predictions, a decision support tool will be developed to help planners and government agencies develop policies to upgrade flood protection and transportation infrastructure based on accepted risk levels during extreme weather events.  This will help ensure optimal spending of public funds to prepare our flood protection and transportation infrastructure for potential future changes in environmental design conditions.
