“…The component-based approach for assessing industrial flood vulnerability assessment is outlined in Figure 1. While traditional flood loss assessment methods (e.g., Kates, 1968;Penning-Rowsell and Chatterton, 1977;Su et al, 2005;Sangrey et al, 1975) and recent implementations such as Hazus (FEMA, 2021) involves the use of depthdamage curves to determine facility-level damage based on an input flood depth, the component-based approach here involves a three-phase process. In Phase 1, flood parameters are identified, and facility and construction information are collected and loaded into databases.…”

Much of the U.S. petrochemical infrastructure is heavily concentrated along the western coast of the Gulf of Mexico within the impact zone of major tropical cyclone events. Flood impacts of recent tropical disturbances have been exacerbated by an overall lack of recognition of the vulnerabilities to process systems from water intrusion, as well as insufficient disaster mitigation planning. Vulnerability assessment methods currently call for the aggregation of qualitative data to survey the susceptibility of industrial systems to floodwater damage. A means to quantify these consequences is less often employed, resulting in a poor translation of the threat of flood hazards to a crucial element of the economy. This paper reviews flood damage assessment for industrial facilities and presents a component-level conceptual methodology to assess the consequences of flood events. To more effectively communicate loss potential from flood events, the proposed methodology utilizes synthetic estimation to calculate repair requirements, shutdown time, and direct cost.

“…In the case of historical regions with multiple TSFs, it is not easy to undertake a comprehensive risk assessment, due to the high cost particularly for sampling and laboratory analysis. On the other hand, in recent years computer‐based flood mapping techniques have been proposed as a valuable approach to understanding and mitigating the potential effects of floods at local and regional scales (e.g., Gouldby et al, 2008; Lamb et al, 2010; Merz et al, 2007; Su et al, 2005). Therefore, the use of computer‐based flood mapping approaches can help to prioritise sites that warrant a comprehensive risk assessment that would include all three steps listed above.…”

Minimizing environmental pollution from Tailings Storage Facilities (TSFs) is one of the key goals of the mining sector. While much attention is given to risks from potential catastrophic failures of large TSFs, there is also a need to assess risks due to noncatastrophic but more frequent releases of contaminants. In response to this need, this article proposes a method for prioritizing TSFs in terms of flood exposure, based on flood maps produced by the Shallow Water Integrated Flood Tool. The method was implemented using a case study of a flood event in the Copiap o city region (Atacama, Chile). A sensitivity analysis was carried out to evaluate the influence of different model configurations and input parameters. The results showed that 10% of all the TSFs in the case study region were exposed to flood waters due to the fluvial dynamics of the Copiapo River. Additionally, the sensitivity analysis revealed that in the event of extreme local precipitation, capable of generating runoff, up to 88% of all the TSFs could have some degree of flood exposure. The results also suggest that flood simulations using satellite-derived terrain data at moderate resolution can be used for a preliminary large-scale assessment of TSF flood exposure.
