Elements: Developing an integrated modeling platform for tectonics, earthquake cycles and surface processes

该项目开发了用户友好和可持续的代码，可以模拟岩石圈的变形以及地貌演变和地震周期。地震、洪水、滑坡和火山等自然灾害处于地质和人类时间尺度的交汇处；模拟不同地质过程之间相互作用的能力为研究全球变化如何在人类时间尺度上扰乱这些过程提供了基线。该项目的目标是将地震周期和地貌演变视为一个与岩石圈长期变形相结合的系统。包括地貌学、构造地质学和地震物理学在内的多个研究团体预计将从该项目实现的新的建模能力中受益。该产品软件扩展了现有的开源代码DES3D(3D中的动态地球解算器)。通过并行计算技术实现的内部增强和可扩展性能，该软件作为一个可靠的集成建模平台发挥作用，可以探索构造、地表过程和地震周期之间的相互作用。该项目包括改善用户对产品代码的体验的措施；基于网络的输入文件生成、可在线阅读和执行的有用文档和教程将使产品代码易于访问和使用。为了促进产品代码的持续开发和维护，采用了现代软件工程实践。基于容器的技术被内置到产品代码中，以创建模型的可复制包装，而无需用户干预。为了确保产品代码将成为现有网络基础设施的宝贵补充，该项目将积极利用进行相关研究的合作者的专业知识。这项由先进数字基础设施办公室颁发的奖项由地球科学部的地球物理计划、构造学计划、地貌学和土地利用动力学计划以及美国国家科学基金会地球科学局内的综合和协作教育与研究司共同支持。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智力价值和更广泛的影响审查标准进行评估，被认为值得支持。

This project develops user-friendly and sustainable code that can simulate lithospheric deformations coupled with landscape evolution and earthquake cycles. Natural hazards such as earthquakes, flooding, landslides, and volcanoes sit at the intersection of geologic and human time scales; the ability to simulate interactions among diverse geologic processes provides a baseline to study how global changes are perturbing these processes on human time scales. The goal of the project is to view earthquake cycles and landscape evolution as a system coupled with long-term lithospheric deformation. Multiple research communities including geomorphology, structural geology and earthquake physics are expected to benefit from the new modeling capability this project enables. The product software extends existing open-source code, DES3D (Dynamic Earth Solver in 3D). With internal enhancements and scalable performance enabled by parallel computing technology, the software functions as a reliable integrated modeling platform that can explore interplay between tectonics, surface processes and earthquake cycles. The project includes measures to improve user experience with the product code; Web-based input file generation, useful documentation and tutorials readable and executable online will make the product code accessible and easy to use. To facilitate sustained development and maintenance of the product code, modern software engineering practices are adopted. Container-based technology is built into the product code to create reproducible packages of a model without user intervention. To ensure that the product code will be a valuable addition to the existing cyberinfrastructure, this project will actively leverage expertise from collaborators who have conducted related research. This award by the Office of Advanced Cyberinfrastructure is jointly supported by the Geophysics Program, the Tectonics Program, the Geomorphology and Land-Use Dynamics Program of the Division of Earth Sciences, and the Division of Integrative and Collaborative Education and Research within the NSF Directorate for Geosciences.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.
