Track I Center Catalyst: Collaborative Center for Landslides and Ground Failure Geohazards

山体滑坡是世界各地山区的常见灾害，它们发生在美国所有州和地区。仅在美国，每年与山体滑坡有关的损失估计超过20亿美元，造成25至50人死亡。1998年至2017年期间，全球山体滑坡造成18，000多人死亡。这一轨道一提案将使用波多黎各作为一个生活实验室，研究山体滑坡，相关的地面故障的危害，以及他们的社区影响。该提案将为轨道2中的国家中心提案开发一个主要枢纽，作为格鲁吉亚理工学院（GT）、波多黎各大学马亚圭斯分校（UPRM）和科罗拉多大学博尔德分校（CUB）之间的合作。这个主要的枢纽将作为一个模型，将研究目标与社区参与，学生教育和劳动力发展相结合。目标包括将历史上代表性不足的群体纳入尖端科学研究，向易受大规模浪费影响的社区传播滑坡科学，并培养新一代主题专家和领导者。为应急管理人员和社区领导人制定的“滑坡准备”计划将以一种有意义的方式加强滑坡准备和灾害应对最佳实践的沟通。波多黎各中心，最终成为滑坡和地面故障地质灾害合作中心，将重点研究滑坡的根本原因和触发机制，并了解地面故障造成的灾害。该中心将提供一个专门为滑坡科学量身定制的现场工作和建模工具的平台。国家中心要解决的科学问题包括：我们能预测复杂地形下的滑坡触发吗？降雨、地形、植被和滑坡风险之间的相互作用是什么？山体滑坡会促进碳的释放或捕获吗？我们能否预测事件后粗泥沙的河流通量及其对未来洪水灾害的影响？第一轨道科学目标包括发展网络基础设施，整合数据和模型，并制定了一个滑坡地质灾害预测系统为波多黎各。这个奖项反映了NSF的法定使命，并已被认为是值得的支持，通过评估使用基金会的知识价值和更广泛的影响审查标准。

Landslides are a common hazard in mountainous terrain worldwide, and they occur throughout all US states and territories. In the US alone, annual landslide-related losses have been estimated to be more than $2B with the loss of 25 to 50 lives. Worldwide landslides claimed more than 18,000 lives between 1998 and 2017. This Track I proposal will use Puerto Rico as a living laboratory to study landslides, related ground failure hazards, and their community impact. This proposal will develop a primary hub for a national center proposal in Track 2 as a collaboration between the Georgia Institute of Technology (GT), the University of Puerto Rico at Mayagüez (UPRM), and the University of Colorado Boulder (CUB). This primary hub will serve as a model for integrating research aims with community engagement, student education, and workforce development. Goals include the inclusion of historically underrepresented groups in cutting-edge scientific research, communicating landslide science to communities vulnerable to mass wasting, and preparing a new generation of subject matter experts and leaders. A “Landslide Ready” program for emergency managers and community leaders will underpin efforts to communicate landslide preparedness and hazard response best practices in a meaningful way.The Puerto Rico hub, and ultimately a Collaborative Center for Landslides and Ground Failure Geohazards, will focus research on the fundamental causes and triggering mechanisms of landslides as well as developing an understanding of hazards cascading from ground failure. The hub will provide a platform for fieldwork and modeling tools tailored specifically for landslide science. Scientific questions to be addressed by the national center include: Can we predict landslide triggering in complicated terrain? What are the interactions between rainfall, topography, and vegetation and landslide risk? Do landslides promote the release or capture of carbon? Can we forecast the post-event riverine flux of coarse sediment and its impacts on future flood hazards? Track I science objectives include developing the cyber-infrastructure for integrating data and models and formulating a landslide geohazard forecasting system for Puerto Rico.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.
