SBIR Phase I: One pass dike and levee characterization system

这个小企业创新研究（SBIR）第一阶段项目将开发一个堤防表征系统。卡特里娜飓风和丽塔飓风以及2008年中西部地区的洪水和决堤清楚地表明了美国堤坝失效的影响，以及主动评估和修复堤坝的必要性。目前的堤防评估方法昂贵、费时，而且通常只能提供稀疏的数据。将在该SBIR下开发的系统将提供有关堤防地下和地表性质的值和变化的近实时的可操作信息。这将通过半自主地收集和处理空间和时间上一致的多传感器数据集来完成。数据处理将通过多传感器数据集的联合反演和自动解释来完成。信息将通过网络界面提供给堤坝和防洪堤的利益相关者，并允许利益相关者根据财产价值和变化做出明智的、基于数据的纠正行动决策。这一系统将大大改善堤防评估工作。该项目的更广泛的影响/商业潜力将是提供比现有方法质量更高、成本更低的堤防和堤防特征的潜力，以及对堤防性能的相关信心。在美国以及荷兰、英国、中国和日本等其他国家，防洪堤共同保护着数千万人的生命和价值数万亿美元的财产。目前，堤防评估的成本在每英里5万到30万美元之间。由于美国的堤坝库存超过10万英里，评估这些堤坝和堤坝的成本给联邦政府、各州和社区带来了巨大的困难，而预算限制有时会导致延迟评估，从而带来潜在的致命和昂贵的后果。该系统将在这里开发，将提供一次高质量，价格合理（约3000美元/英里），随时可以获得有关堤坝和防洪堤地下和地表特性的近实时全面信息。这将使利益相关者能够就堤防质量、纠正措施的需要和位置做出明智的决定。由此产生的关于堤坝强度的科学和基于数据的知识将为社会带来广泛的利益。

This Small Business Innovation Research (SBIR) Phase I project will develop a dike and levee characterization system. Hurricane Katrina and Rita and the flooding and breaching of levees in the Midwest in 2008 clearly demonstrated the impact of levee failures in the US, and the need for proactive levee assessment and repair. Current approaches to dike and levee assessments are expensive, invasive and lengthy and generally only provide sparse data. The system which will be developed under this SBIR will provide actionable information in near real time on the values of, and changes in, subsurface and surface properties of dikes and levees. This will be done by semi autonomously collecting and processing spatially and temporally coincident multi sensor datasets. Data processing will be done through joint inversion and automated interpretation of multi sensor datasets. Information will be made available to stakeholders in dikes and levees through a web interface, and will allow stakeholders to make informed and data based decisions on the need for corrective actions based on property values and changes. This system should substantially improve dike and levee assessment practices.The broader impact/commercial potential of this project will be the potential to provide dike and levee characterization with improved quality and for substantially lower costs than current approaches, and the associated confidence in levee performance. In the US and in other countries such as the Netherlands, the UK, China and Japan levees and dikes collectively protect tens of millions of lives and trillions of dollars' worth of property. Currently dike and levee assessment costs between $50,000 and $300,000 per mile. As the US levee inventory is over 100,000 miles, the costs to assess these dikes and levees pose significant hardship for the federal government, states and communities, and budget constraints sometime result in deferred assessments with potential deadly and expensive consequences. The system which will be developed here will provide in a single pass high quality, affordable (approximately $3000/mile), readily accessible comprehensive information on dike and levee subsurface and surface properties in near real time. This will allow stakeholders to make informed decisions on dike quality and the need for, and location of any corrective actions. The resulting science and data based knowledge about levee strength will provide broad benefits to society.
