The Community Surface Dynamics Modeling System (CSDMS) supports a diverse community of experts who model Earth surface processes. It does so by developing, supporting, and disseminating integrated software modules that predict the movement of fluids, and the flux (production, erosion, transport, and deposition) of sediment and solutes in landscapes and their sedimentary basins. CSDMS provides open-access to numerical models, maintains data for modelers and educational resources on earth science modeling for teachers, provides computing resources for members, offers help in advanced model coupling, and is a platform of discussion for earth science research.This project aims to enhance the CSDMS cyber-infrastructure. The current CSDMS Modeling Framework will be extended for use within a web browser, on a wider variety of computational platforms, and on other high performance computing clusters to ensure robustness and sustainability of the framework. Community-generated models will be converted into ?plug-and-play? components through the development of automated wrapping tools. Methods for quantifying model uncertainty will be adapted. Benchmarking data will be incorporated into the CSDMS modeling framework to support model inter-comparison. Finally, a robust mechanism for ingesting and utilizing semantic mediation databases will also be developed within the Modeling Framework. In addition, six new community initiatives will be pursued: 1) an Earth - ecosystem modeling initiative to capture ecosystem dynamics and ensuing interactions with landscapes, 2) a geodynamics initiative to investigate the interplay among climate, geomorphology, and tectonic processes, 3) an Anthropocene modeling initiative, to incorporate mechanistic models of human influences, 4) a coastal vulnerability modeling initiative, with emphasis on deltas and their multiple threats and stressors, 5) a continental margin modeling initiative, to capture extreme oceanic and atmospheric events generating turbidity currents in the Gulf of Mexico, and 6) a CZO Focus Research Group, to develop compatibility between CSDMS architecture and protocols and Critical Zone Observatory-developed models and data.CSDMS streamlines the computer modeling of myriad societally relevant processes, including melting glaciers, landslides, erosion, wetland evolution, water cycling, flooding, and coastal change. Through its community support mechanisms, CSDMS catalyzes the process of idea generation and hypothesis testing, enabling the rapid creation and application of models tailored to specific settings, scientific problems, and time scales. CSDMS? community approach allows the efficient development of models that are more powerful than could be developed by any single group ? redundancy is reduced, models are better vetted, the capability for innovation is expanded, and energy can be focused towards earth-surface domains that are poorly represented or controversial. CSDMS ensures that models are accessible and transparent by soliciting and publishing model documentation. Staff at the CSDMS Integration Facility convert models into modules that can be easily coupled together; this modularity gives rise to new applications for existing software. This new award will enable CSDMS to enhance its cyber-infrastructure by developing: 1) software products and approaches designed to be accessible, easy to use, and relevant, 2) new community initiatives to advance earth-surface process modeling across many disciplines, and 3) educational products and training workshops aimed at various entry levels.

社区表面动力学建模系统（CSDMS）支持模拟地球表面过程的各种专家社区。它通过开发、支持和传播综合软件模块来实现这一目标，这些模块预测流体的运动以及景观及其沉积盆地中沉积物和溶质的通量（产生、侵蚀、运输和沉积）。 CSDMS提供开放式的数值模式存取、为建模者维护数据、为教师维护地球科学建模的教育资源、为会员提供计算资源、提供高级模型耦合的帮助，以及为地球科学研究提供讨论平台。 目前的CSDMS建模框架将扩展到Web浏览器、更广泛的计算平台和其他高性能计算集群中，以确保框架的鲁棒性和可持续性。社区生成的模型将转换为？即插即用通过开发自动化包装工具，将采用量化模型不确定性的方法。基准数据将纳入CSDMS建模框架，以支持模型之间的比较。最后，还将在建模框架内开发一种用于引入和利用语义中介数据库的健壮机制。 此外，还将开展六项新的社区举措：1）地球-生态系统建模倡议，以捕获生态系统动态和随后与景观的相互作用，2）地球动力学倡议，以调查气候、地貌和构造过程之间的相互作用，3）人类世建模倡议，以纳入人类影响的机械模型，4）沿海脆弱性建模倡议，重点是三角洲及其多种威胁和压力源，5）大陆边缘建模倡议，以捕捉在墨西哥湾产生浊流的极端海洋和大气事件，以及6）CZO焦点研究小组，开发CSDMS架构和协议与临界区观测站之间的兼容性-CSDMS简化了无数社会相关过程的计算机建模，包括冰川融化，山体滑坡，侵蚀，湿地演变，水循环，洪水和海岸变化。通过其社区支持机制，CSDMS促进了想法生成和假设检验的过程，使模型的快速创建和应用能够适应特定的环境，科学问题和时间尺度。CSDMS？社区方法允许有效地开发比任何单一团体开发的模型更强大的模型？减少了冗余，更好地审查了模型，扩大了创新能力，可以将精力集中在代表性差或有争议的地球表面领域。CSDMS通过征求和发布模型文档来确保模型的可访问性和透明性。CSDMS集成设施的工作人员将模型转换为可以轻松耦合在一起的模块;这种模块化为现有软件带来了新的应用程序。 这一新奖项将使CSDMS能够通过开发以下内容来增强其网络基础设施：1）设计为可访问，易于使用和相关的软件产品和方法，2）新的社区计划，以推进跨多个学科的地球表面过程建模，以及3）针对各种入门级的教育产品和培训研讨会。
