Template:Drop box What are the different CSDMS groups
The Terrestrial Working Group (currently 1075 members) deals with erosion, sediment and solute transport, and deposition on land. The processes concerned are wide ranging, from the sculpting of glacial landscapes to the formation of soil and the transport of erosional materials to the coastline.
The Group's working goals include:
- Evaluate present knowledge of processes in terrestrial environments (mountains, plains, deserts, jungles, etc., as well as human impacts in these settings) and identify the numerical models presently in use.
- Identify gaps in knowledge and areas where model development is needed. Such gaps include processes about which very little is known -- such as the dynamics of bedrock landscapes and the evolution of grain size populations -- and processes that are partly understood but for which numerical codes are under-developed.
- Define and address interesting and relevant proof-of-concept questions. These are science questions that use the CSDMS paradigm to improve our understanding of landscape evolution and its links with the atmosphere, lithosphere, biosphere, hydrosphere, and cryosphere. Proof-of-concept questions range from decadal to geological in time scale, and from small watersheds to mountain ranges in spatial scale.
- Work with the community to populate the CSDMS model toolkit with models and software tools of all types. These include large, multi-faceted landscape evolution models as well as simple, semi-analytical representations of a single process, hydrodynamic codes such as open-channel flow in 1D and 2D, tools for digital-terrain data processing, and a great many others -- any software, in fact, that can help the community better understand the dynamics of the earth's changing landscapes.
The Coastal Working Group (currently 806 members) deals with delta, estuary, bays and lagoons, and nearshore challenges.
Its working goals are to:
- Evaluate present knowledge of processes in coastal environments (nearshore, inner shelf, barrier islands, sandy coastlines, rocky coastlines, estuaries, lagoons and marshes, eolian, deltas)— including the human component of those systems (i.e. direct couplings between human manipulations and landscape evolution in deltas and coastlines)—and identify the numerical models presently in use.
- Identify gaps in knowledge and areas where model development is needed—both poorly understood phenomena requiring basic research and exploratory modeling, and better understood systems for which model reliability should be improved.
- Define and address interesting and relevant proof-of-concept questions—questions that require linking together models of different environments, preferably spanning between coastal and terrestrial or marine environments.
- Work with the community to populate the CSDMS model toolkit with models of all sorts, ranging from analytical and simplified numerical models that can be shared with the scientific community in stand-alone form, to numerical models that can be linked to models of other environments, via CSDMS, to allow new sorts of questions to be addressed.
The Marine Working Group (currently 491 members) deals with shelf, carbonate, slope, and deep marine challenges.
CSDMS plans on strong and fully integrated Education and Knowledge Transfer components. CSDMS EKT (currently 363 members) will focus its knowledge transfer efforts on three CSDMS end-user groups: researchers, planners, and educators. CSDMS will target:
- Researchers with model and visualization tools for the testing of hypotheses in support of data interpretation, and development of field programs. The archiving of benchmark data sets, documented source code, and the ability to download models with user-friendly graphical interfaces are key components of the Center's knowledge transfer objective.
- Planners with decision-making tools to run scenarios, and relate GIS output to environmental factors and land use while quantifying uncertainties.
- Educators with pre-packaged models to help illustrate surface processes, tools to build intuition with “what-if”-type model runs, case studies that integrate field data and model simulations, and prepare exploratory exercises for students. The Web-Data Specialist and EKT Specialist will be expected to work closely together and will be carefully selected to have good popular-science writing skills.
Our principal Education audiences are university students, professionals, teachers at the secondary school and college levels, and the general public. Resources to support this effort will not become available until the third year of the CSDMS effort, due to NSF budget reductions. CSDMS will jump-start our Education and KT activities by coordinating them closely with the EKT programs at the National Center for Earth-surface Dynamics (NCED), a funded NSF Science and Technology Center devoted to developing a predictive, quantitative understanding of the processes that shape the Earth's Surface.

The Cyberinformatics and Numerics Working Group (currently 311 members) deals with technical computational aspects of the CSDMS, ensures that the modeling system properly functions and is accessible to users; software protocols are maintained, along with model standardization and visualization; and works with our cyberinformatic partners.
Welcome to the CSDMS Hydrology Focus Research Group (FRG). The Hydrology FRG is a research group (currently 837 members), that is additionally co-sponsored by CUAHSI, the Consortium of Universities for the Advancement of Hydrologic Science, Inc. Our goal is to provide input to the CSDMS effort on how to best represent hydrological processes and models within CSDMS. Another role that the Hydrology FRG will play is to facilitate links to other community hydrologic modeling activities, including those led by CUAHSI.
The Carbonates and Biogenics Focus Research Group (C-FRG) (currently 161 members) has been created with the aim of identifying and then addressing the grand challenges for fundamental research on ancient and recent carbonates and biogenics systems. This aim will be accomplished through creation of the next generation of numerical carbonate and biogenic process models under the umbrella of the CSDMS initiative. The initiative is driven by the idea that open-source numerical models and associated quantitative datasets can be state-of-the-art repositories for our knowledge of how carbonate and biogenic systems work, as well as being experimental tools to apply to develop and enhance that knowledge.
A first step in addressing this aim occurred in February 2008 when various members of the carbonate community attended a workshop at the Colorado School of Mines. The purposes of the workshop were to identify grand challenges for fundamental research on ancient and recent carbonate systems, and to identify promising areas for advancing the next generation of numerical process models to enhance our ability to meaningfully and accurately model carbonate systems. Thirty-one attendees from academia and industry worked to initiate a carbonate community across a broad spectrum of disciplines, including sedimentology, stratigraphy, geobiology, oceanography, paleoclimatology, numerical process modeling, and carbonate diagenesis. More about the meeting and its results are on the web, at: Carbonate systems
The next steps planned to advance the group’s aims were to:
- develop the carbonate community
- upload existing model code and information into the CSDMS repository so that people can start to use and further develop the various carbonate numerical models
- upload useful data on carbonate systems (e.g. digitized maps of modern and ancient systems, geochemical data, bed thickness data from outcrop and core analysis, and so on) to the CSDMS data repository
- meet with a small, focused group in early 2009 to tie up loose ends from the last meeting, and, most importantly, to draft a series of research proposals to be submitted to NSF and elsewhere, to fund the first stages of C-FRG research.
To meet these steps, the Carbonate Focus Research Group met again in January 26-27, 2009 at the CSDMS Integration Facility. The specific purpose of this meeting was to further build the carbonate focused research group research programme by doing two things:
- Preparing one or more draft proposal to NSF to fund research programs focused on development of next-generation carbonate numerical forward models. Although the focus of these proposals will be model development, the proposed work could also cover aspects of data gathering, concept development, and quantitative analysis of modern and ancient carbonates to support generation of meaningful, useful models; and
- Deciding on the best structure and working practices for the group to achieve the stated aims.
See Carbonate FRG 2009 for more information about the second meeting.

This is the first Geographically-Focused Research Group (GFRG) (currently 122 members) associated with CSDMS. The group is a partnership between CSDMS and the Chesapeake Community Modeling Program (CCMP, http://ches.communitymodeling.org/) currently run by the Chesapeake Research Consortium.
CCMP developed as the Chesapeake Bay research community came together to cooperatively build an open source system of watershed and estuary models. Through support from CRC member institutions and the NOAA Chesapeake Bay Office, CCMP modelers have committed to developing a modeling framework that will enable free and open access to code specific to the Chesapeake Bay region. As a complementary activity to the Chesapeake Bay Program (CBP) modeling program, the Chesapeake Community Model Program will strive to develop a comprehensive model consisting of interchangeable individual modules covering all aspects of hydrodynamics, ecosystem dynamics, trophic exchanges, and watershed interactions towards a future linked watershed-estuary model. There are obvious areas of overlap between CSDMS and CCMP, and the CSDMS Chesapeake FRG intends to capitalize on synergies from both programs. We continue to solicit members of the Working Group, and your participation would be welcome.
Our first meeting was held at the Chesapeake Bay Program Office, Annapolis, MD, on April 3, 2009, and our second meeting was held at the Virginia Institute of Marine Science, Gloucester Point, VA, on November 10, 2009. These meetings aimed to get attendees up to speed on the model integration pathway that CSDMS is employing and to solicit guidance in developing short, intermediate and longer term goals for the Chesapeake FRG.
