  1. Cyberinfrastructure and Numerics: Strategic Plan 2013-1017EckartMeiburg

  2. Research interests of Cyber WG members present at CSDMS 2.0 • Central scientific application around which our efforts can crystallize: Computational fluid dynamics and sediment transport • Have available a suite of sophisticated computational codes to cover range of length scales: Grain-scale code (Biegert, Borden and Meiburg), Open Foam including particles (Schmeeckle, Liu, Hsu), TURBINS (Nasr-Azadani and Meiburg), TURBINS-LES (Radhakrishnan and Meiburg), Delft 3D (Jagers), ROMS (Arango). • Expertise on Cyberinfrastructure: software componentization, coupling, interoperability, standards, semantics, algorithms, databases, social networks, hardware … • Possible extension to ecology: coupling of fluid dynamics/sediment transport with vegetation, larvae transport, transport of nutrients and pollutants …

  3. Key directions and long-term goals • Make existing models accessible and useful to the widest possible community • Create legacy databases that can benefit wide research community • Develop nested models to address multiscalephenomena • Help improve capabilities of reduced complexity models • Uncertainty quantification • Perform model inter-comparisons • Develop strong ties with EarthCube (Scott Peckham, Boyana Norris, Anna Kelbert)

  4. Medium term goals • Perform model inter-comparisons between TURBINS, Open Foam, LES, RANS models for a few canonical sediment transport problems • Target one or two of the above codes for creating demo examples of computational models and databases that address the needs of the community, such as: - Standardized way of accessing models/databases - Easy access even from developing countries (outreach) - Databases need to be interoperable (“internet of things”) - Ability to query datasets for various quantities (velocities, sediment concentrations etc.) at arbitrary locations - Allow for easy visualization of databases

  5. Medium term goals (cont’d) - Accommodate large data files (bring model to the data, instead of the other way around?) - Searchable in automated fashion (semantics) - Ability to feed real-life data into ongoing simulations (such as updated rainfall statistics) - Employ social networking tools to build user communities, track user experience, create discussion forums (Google groups) • Continue to provide Python, MATLAB, Octave clinics, offer Q&A sessions, post on YouTube • Create systematic infrastructure for performing model comparisons

  6. “Earth-on-a-Chip:”Advanced modeling concepts in support of the environment, water and energy resources
