Abstract

: The demand for inexpensive and reliable warning systems has increased in recent years as a result of the increase in the number and severity of flood disasters. A new generation of low-cost sensors for flood monitoring and warning is being developed by the federal government and private sectors, in some cases collaboratively. We perform a benefit-cost analysis of this new product category, (i.e., low-cost flood inundation sensors), which can readily be deployed in a wireless or internet of things network. The use of these sensors can improve the coverage and lengthen the lead time of flood warning systems. The production costs of this new technology are only a fraction of those of existing sensors with similar capability and reliability, and operating costs are modest. Benefits depend on such factors as the ability to improve lead times of warnings to reduce property damage, deaths, and injuries from floods as well as the extent of adoption of the new sensors. Our analysis indicates a benefit – cost ratio of 1.4 to 1. However, our results are based on several assumptions. Hence, we have undertaken extensive sensitivity analyses to determine that our results are robust. DOI: 10.1061/(ASCE)NH.1527-6996.0000596. © 2022 American Society of Civil Engineers.

低成本洪水淹没传感器的成本效益分析

：近年来，由于洪水灾害的数量和严重程度的增加，对廉价可靠的预警系统的需求也在增加。联邦政府和私营部门正在开发新一代低成本的洪水监测和预警传感器，在某些情况下是合作开发的。我们对这一新产品类别（即低成本洪水淹没传感器）进行了效益成本分析，该产品可以很容易地部署在无线或物联网网络中。使用这些传感器可以提高洪水预警系统的覆盖范围并延长交付周期。这项新技术的生产成本只是具有类似能力和可靠性的现有传感器的一小部分，运营成本也不高。收益取决于以下因素，如提高警报提前期以减少洪水造成的财产损失、死亡和伤害的能力，以及新传感器的采用程度。我们的分析表明，效益成本比为1.4比1。然而，我们的结果是基于几个假设的。因此，我们进行了广泛的敏感性分析，以确定我们的结果是稳健的。DOI:10.1061/（ASCE）NH.1527-6996.0000596。©2022美国土木工程师学会。

期刊介绍： The Natural Hazards Review addresses the range of events, processes, and consequences that occur when natural hazards interact with the physical, social, economic, and engineered dimensions of communities and the people who live, work, and play in them. As these conditions interact and change, the impact on human communities increases in size, scale, and scope. Such interactions necessarily need to be analyzed from an interdisciplinary perspective that includes both social and technical measures. For decision makers, the risk presents the challenge of managing known hazards, but unknown consequences in time of occurrence, scale of impact, and level of disruption in actual communities with limited resources. The journal is dedicated to bringing together the physical, social, and behavioral sciences; engineering; and the regulatory and policy environments to provide a forum for cutting edge, holistic, and cross-disciplinary approaches to anticipating risk, loss, and cost reduction from natural hazards. The journal welcomes rigorous research on the intersection between social and technical systems that advances concepts of resilience within lifeline and infrastructure systems and the organizations that manage them for all hazards. It offers a professional forum for researchers and practitioners working together to publish the results of truly interdisciplinary and partnered approaches to the anticipation of risk, loss reduction, and community resilience. Engineering topics covered include the characterization of hazard forces and the planning, design, construction, maintenance, performance, and use of structures in the physical environment. Social and behavioral sciences topics include analysis of the impact of hazards on communities and the organizations that seek to mitigate and manage response to hazards.
