Emergency operations center

INTRODUCTION: Considering the important and sensitive position of Emergency Operations Centers (EOC) and little scientific research has been done on the subject, the purpose of this comparative study is to identify the structural and functional requirements of EOCs. METHODS: In this comparative research, structural and functional requirements and considerations of modern EOCs were extracted to facilitate the process of managing operations and responding to disasters by studying the guidelines and standards for the design and construction of modern EOCs, as well as examining the experiences of different countries in using and operating these centers. FINDINGS: By reviewing the studies, these components were extracted as the important structural and functional requirements of these centers including: common hazards in the region, the purpose of creating an EOC, the flexibility and multi-purpose nature of the EOC, audio and visual features of the operation control room, the number of administrative and operational positions, ergonomics and allocated space, required and technologies, the existence of a space for holding group meetings as well as people's rest, the amount of allocated budget and also the conditions of people's access to modern EOC. CONCLUSION: Based on the findings, assessing the risks in the region and developing different possible scenarios, along with paying attention to the structural and functional requirements of modern EOCs based on the obtained criteria, can improve the disaster management process.

INTRODUCTION: One of the technologies that can have significant results in the field of crisis management is remote sensing, which has the ability to quickly and accurately assess floods and is considered an important and safe tool for reducing risk and responding to this hazard. METHODS: In this study, radar data was used to quickly estimate the areas affected by the flood in the Chabahar city in January 2020, and the Normalized Difference Water Index (NDWI) was used to verify the validity. FINDINGS: According to the research findings, the use of Sentinel-1 radar satellite data in critical situations such as flooding has a high potential for rapid and accurate monitoring of affected areas. Comparison of the results extracted from radar images with the NDWI based on Sentinel-2 optical images also showed that although there are differences between the two methods, a significant overlap was recorded between their results, indicating the relative validity of radar data for estimating flooded areas. CONCLUSION: Overall, it seems that the benefits of using radar images to estimate areas affected by floods are undeniable and that by optimizing the algorithms and methods used, desirable results can be achieved in line with the desired goal.
