1464308SonderThis EAGER grant will suport exploration of experimental, design, and management concepts for a potential user facility to allow for unprecedented in scale (10-100 m) experimental simulation of terrestrial mass flows (5-10 t of material). An envisioned mass flow apparatus (MFA) on the size scale and with capabilities hoped for (e.g., multiple material release modalities, variable ramp inclination and surface topography as well as a range of ramp embedded sensing modalities) was a concept recommendation of a recent NSF supported workshop that engaged an international community of volcanologists. As such the PIs will first target the considerations necessary to simulate pyroclastic flows though the MFA would be suitable for experimental study of landslides. The MFA would allow for study of mixed phase mass flows where initial boundary conditions are controlled and the resultant deposits would be studied to help improve numerical models of the behavior of mass flows and to ultimately use those models to help mitigate mass flow hazards. Topics to be further studied using EAGER support include: 1) the sourcing, handling, delivery and preparation of suitable starting materials for target simulations; 2) design of the variable inclination ramp, provision for modification of surface morphology and integration of specific sensing modalities and engineering consideration of the ramps structural design and response to dynamic loads of the mass scales envisioned; 3) consideration of management issues (e.g., time and costs of experiment set up and clean up, scheduling, cost recovery estimates for target experiment types and longer term usage considerations ? maintenance.) The envisioned MFA offers a potentially transformative experimental resource for study of hazardous mass flows under controlled settings at unprecedented scales and with sensing capabilities that cannot be applied in situ under natural conditions. This EAGER grant will support the additional exploratory considerations necessary to refine MFA design consideration and management concepts that could result in a tractable MFA that could support broad use by the geoscience community.

1464308Sonder 这项 EAGER 赠款将支持对潜在用户设施的实验、设计和管理概念的探索，以便对陆地质量流（5-10 吨物质）进行前所未有的规模（10-100 m）实验模拟。 预期的质量流量装置 (MFA) 具有所需的尺寸和功能（例如，多种材料释放模式、可变坡道倾角和表面形貌以及一系列坡道嵌入式传感模式），这是最近 NSF 的概念推荐支持国际火山学家参与的研讨会。 因此，虽然 MFA 适用于滑坡的实验研究，但 PI 将首先考虑模拟火山碎屑流所需的考虑因素。 MFA 将允许研究混合相质量流，其中初始边界条件受到控制，并对所得沉积物进行研究，以帮助改进质量流行为的数值模型，并最终使用这些模型来帮助减轻质量流危险。 使用 EAGER 支持进一步研究的主题包括： 1) 用于目标模拟的合适起始材料的采购、处理、交付和准备； 2) 可变倾角坡道的设计，提供表面形态的修改和特定传感模式的集成以及坡道结构设计的工程考虑以及对预期质量尺度的动态载荷的响应； 3）考虑管理问题（例如，实验设置和清理的时间和成本、调度、目标实验类型的成本回收估计以及长期使用考虑因素？维护。）设想的 MFA 为研究提供了潜在的变革性实验资源在受控环境下以前所未有的规模检测危险物质流，其传感能力无法在自然条件下就地应用。 这笔 EAGER 拨款将支持完善 MFA 设计考虑和管理概念所需的额外探索性考虑，从而形成易于处理的 MFA，支持地球科学界的广泛使用。
