项目摘要
This proposal focuses on advancing the breadth and depth of understanding of the hazards associated with pyroclastic density currents (PDCs). The proposed study will focus on five overarching goals: 1) developing a general physical/sedimentological model applicable to all types of PDCs; 2) evaluate the accuracy of numerical models in representing PDC-related phenomena through community-based validation and benchmarking exercises; 3) drive future research on PDC hazard assessment (e.g., "validation" experiments, field measurements, uncertainty analysis); 4) provide a community-wide interpretation framework for volcanic flow hazard assessment studies; 5) developing quantitative skills in geoscience education and increasing awareness of the community about the potential and limits of numerical tools ("model literacy") and the complementarity of experimental (both laboratory and field based) and numerical studies. This framework will provide critical information about the uncertainties in hazard assessments that depend on these models. The drive for this knowledge stems from the limited success of current hazard assessment studies to capture the real hazard potential of such volcanic flows. The broader goals for the proposed work are: (1) bringing multi-disciplinary teams together to discuss the relationship between field studies, computational modeling and hazard assessment; (2) increasing familiarity with and limitations of computational modeling tools to both geoscience students and the broader community; and (3) tailoring the hazard assessment to the needs of the user communities.The general approach is based on an iterative process of integrating data, theories and models. In this process, the data collection (through field investigations, laboratory experiments, remote sensing, monitoring and numerical modeling) allow investigators to revisit and revise scientific theories and principles (for example, a general physical/sedimentological PDC model), which then serve as a basis for computational and experimental models (through calibration, validation, benchmarking and prediction) that can then be applied to the collected data to improve the understanding of the dynamics of PDCs, as well as their hazard assessment studies. This integrative study will follow the methodology proposed for the validation of computational fluid dynamics codes designed to simulate complex industrial and technological systems, based on a hierarchical process of comparing numerical models with experiments and observations. In addition, the Spreadsheets across the Curriculum (SSAC) educational model (https://serc.carleton.edu/sp/ssac/index.html) will be integrated into the VHub cyberinfrastructure (www.vhub.org) to: (1) enhance computational literacy in the geosciences by promoting problem-solving using a structured environment, (2) develop, share and disseminate all activities and deliverables related to model validation and benchmarking efforts that will serve as a basis to drive future research on volcanic flow hazard assessment studies.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
本提案的重点是推进与火山碎屑密度电流(PDCs)相关的危害的理解的广度和深度。建议的研究将集中在五个总体目标上:1)建立一个适用于所有类型pdc的一般物理/沉积学模型;2)通过基于社区的验证和基准测试,评估数值模型在表征pdc相关现象方面的准确性;3)推动PDC危害评估的未来研究(如“验证”实验、现场测量、不确定度分析);4)为火山流危害评估研究提供社区范围的解释框架;5)在地球科学教育中发展定量技能,提高社区对数值工具的潜力和局限性的认识(“模型素养”),以及实验(实验室和实地)和数值研究的互补性。该框架将提供关于依赖于这些模型的危害评估的不确定性的关键信息。推动这种知识的动力源于目前的危害评估研究在捕捉这种火山流的真正潜在危害方面取得的有限成功。拟议工作的更广泛目标是:(1)将多学科团队聚集在一起,讨论实地研究、计算建模和危害评估之间的关系;(2)提高地球科学学生和更广泛的社区对计算建模工具的熟悉程度和局限性;(3)根据用户群体的需要调整危害评估。一般的方法是基于整合数据、理论和模型的迭代过程。在这个过程中,数据收集(通过实地调查、实验室实验、遥感、监测和数值模拟)使研究人员能够重新审视和修改科学理论和原理(例如,一般的物理/沉积PDC模型),然后作为计算和实验模型的基础(通过校准、验证、基准和预测),然后可以应用于收集的数据,以提高对PDCs动态的理解,以及它们的危害评估研究。这项综合研究将遵循为模拟复杂工业和技术系统而设计的计算流体动力学代码的验证所提出的方法,该方法基于将数值模型与实验和观察相比较的分层过程。此外,跨课程电子表格(SSAC)教育模式(https://serc.carleton.edu/sp/ssac/index.html)将整合到VHub网络基础设施(www.vhub.org)中,以便:(1)通过促进使用结构化环境解决问题来提高地球科学的计算素养;(2)开发、分享和传播与模型验证和基准工作相关的所有活动和可交付成果,这些活动和可交付成果将作为推动未来火山流危害评估研究的基础。该奖项反映了美国国家科学基金会的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
