Collaborative Research: SI2-SSE: Component-Based Software Architecture for Computational Landscape Modeling

目前，整体计算景观模型还没有广泛采用的软件惯例。为了填补这一重要空白，该项目通过引入基于组件的软件开发方法来适应和增强现有的景观建模代码。 该项目调整和增强了现有的模型-- CHILD（斜坡综合景观开发）--以提供一套可互操作的独立建模组件，这些组件提供了灵活的模块化景观建模方法，这些方法与NSF资助的社区表面动力学建模系统（CSDMS）基础设施完全兼容。 雅阁CSDMS的架构，将开发的软件也将采用通用组件架构软件架构的标准和工具。 包括一个接口的设计，用于与开发的组件进行通信。 最终结果将是一组独立的、可互操作的C++软件建模模块，这些模块与CSDMS建模工具包以及CCA结构的标准和工具兼容。 该软件将根据野火后侵蚀的数据进行测试。选择这种方法是为了给用户提供最大的灵活性，允许他们即插即用，将选定的计算模块无缝连接在一起，使组件的自定义组合能够支持各种研究主题的建模。 工作将包括开发一个网格引擎，以处理规则和非结构化网格和时空降雨输入接口，以及一个表面水文组件，沉积物侵蚀沉积组件，植被组件和模拟驱动程序。如果成功的话，这个项目将通过建立一个新的建模平台和为科学创建必要的软件基础设施来影响地球和环境科学的许多分支，其应用范围包括水文学，土壤侵蚀，构造学，地貌学，植被生态学，地层学和行星科学。 这项工作的更广泛影响包括为本科生和高中生创建课堂建模练习，以及支持在STEM领域性别代表性不足且在EPSCoR州机构任职的PI。 它还包括为研究生和博士后以及来自新奥尔良地区历史上的黑人大学泽维尔大学的少数民族本科生提供计算地球科学方面的劳动力培训。

Presently there are no widely adopted software conventions for holistic computational landscape models. To fill this important gap this project adapts and enhances existing landscape modeling codes by introducing a component-based approach to software development. This project adapts and enhances an existing model -- CHILD (Channel-Hill slope Integrated Landscape Development) -- to provide a set of interoperable, independent modeling components that provide flexible and modular approaches to landscape modeling which are fully compatible with the NSF-funded Community Surface Dynamics Modeling System CSDMS) infrastructure. In accord with the CSDMS architecture, the software to be developed will also employ the standards and tools of the Common Component Architecture (CCA) software architecture. Included is the design of an interface for communication with and between the developed components. The end result will be a set of independent, interoperable C++ software modeling modules that are compatible with the CSDMS modeling toolkit as well as the standards and tools of the CCA structure. The software will be tested against data on post-wildfire erosion.This approach was selected to provide maximum flexibility to users by allowing them to plug-and-play, seamlessly linking together selected computing modules to enable custom combinations of components to support modeling for a wide variety of research topics. Work will include the development of a gridding engine to handle both regular and unstructured meshes and an interface for space-time rainfall input, as well as a surface hydrology component, a sediment erosion-deposition component, a vegetation component, and a simulation driver. If successful this project will impact many branches of the Earth and environmental sciences by building a new modeling platform and creating essential software infrastructure for science with applications that span hydrology, soil erosion, tectonics, geomorphology, vegetation ecology, stratigraphy, and planetary science. Broader impacts of the work include creation of classroom modeling exercises for both undergraduate and high schools students, and support of a PI whose gender is under-represented in the STEM fields and who is employed at an institution in an EPSCoR state. It also includes workforce-training in computational geoscience for graduate students and a postdoc as well as minority undergraduates from Xavier University, a Historically Black University in the New Orleans area.
