项目摘要

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.

该项目开发了用户友好且可持续的代码，可以模拟岩石圈变形以及地貌演化和地震周期。地震、洪水、山体滑坡和火山等自然灾害处于地质和人类时间尺度的交叉点；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化视为一个与长期岩石圈变形相结合的系统。包括地貌学、结构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提供的新建模功能中受益。该产品软件扩展了现有的开源代码 DES3D（3D 动态地球解算器）。借助并行计算技术实现的内部增强和可扩展性能，该软件可作为可靠的集成建模平台，可以探索构造、表面过程和地震周期之间的相互作用。该项目包括改善产品代码用户体验的措施；基于网络的输入文件生成、在线可读和可执行的有用文档和教程将使产品代码可访问且易于使用。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。基于容器的技术内置于产品代码中，无需用户干预即可创建可重现的模型包。为了确保产品代码成为现有网络基础设施的有价值的补充，该项目将积极利用进行相关研究的合作者的专业知识。该奖项由高级网络基础设施办公室颁发，并得到美国国家科学基金会理事会地球物理学项目、构造学项目、地貌学和土地利用动力学项目以及美国国家科学基金会理事会综合与协作教育与研究部的联合支持。地球科学。该奖项反映了 NSF 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。
