About CSDMS

A brief introduction of how your research can benefit from CSDMS
 
 The Community Surface Dynamics Modeling System (CSDMS) deals with the Earth's surface - the ever-changing, dynamic interface between lithosphere, hydrosphere, cryosphere, and atmosphere. We are a diverse community of experts promoting the modeling of earth surface processes 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:
* Produces protocols for community-generated, continuously evolving, open software
* Distributes software tools and models
* Provides cyber-infrastructure to promote the quantitative modeling of earth surface processes
* Addresses the challenging problems of surface-dynamic systems: self-organization, localization, thresholds, strong linkages, scale invariance, and interwoven biology & geochemistry
* Enables the rapid development and application of linked dynamic models tailored to specific landscape basin evolution (LBE) problems at specific temporal and spatial scales
* Partners with related computational and scientific programs to eliminate duplication of effort and to provide an intellectually stimulating environment
* Supports a strong linkage between what is predicted by CSDMS codes and what is observed, both in nature and in physical experiments
*Supports the imperatives in Earth Science research: 
:# discovery, use, and conservation of natural resources;
:# characterization and mitigation of natural hazards;
:# geotechnical support of commercial and infrastructure development;
:# stewardship of the environment; and
:# terrestrial surveillance for global security.

About Chesapeake WG

__NOCACHE__
Goals
This is the first Geographically-Focused Research Group (GFRG) (currently 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.
If you are interested in learning more about these meetings, please visit the Chesapeake FRG Reports page. If you would like to participate in the discussions and meetings of the CSDMS Chesapeake Focus Research Group, we invite you to join the group through the link below.

About Coastal Vulnerability Initiative

__NOCACHE__
Goals
Welcome to the CSDMS Coastal Vulnerability Initiative page. The Coastal Vulnerability Initiative (currently members) is focuses on deltas and their multiple threats and stresses. With most of the world’s megacities and a majority of the world’s population living near the coast, sealevel rise and other environmental stressors are expected to have profound societal and economic consequences globally and could lead to large (between 25% and 70%) losses of the world’s wetlands. Globally, trapping of sediment in reservoirs and channeling of river flows by levees and other structures has significantly reduced the natural supply of terrestrial sediment to the coastal zone, resulting in sinking deltas and eroding coastlines.
The National Research Council 2012 report recommends interdisciplinary research on coastal environments to lay the groundwork for understanding and forecasting the response of coastal landscapes to sea-level rise, climate change, and human and natural disturbance. For this initiative, CSDMS is currently participating in two large community efforts: 
# Frontiers of Earth System Dynamics Delta Dynamics Collaboratory (NSF funded), and
# Global scale assessment of threatened river delta systems (NASA funded).
The two projects are mutually supportive, with the latter providing a geographically global perspective.

About Continental Margin Initiative

__NOCACHE__
Goals
Welcome to the CSDMS Continental Margin Initiative page. The goal of the Continental Margin Initiative (currently members) is to capture extreme oceanic and atmospheric events generating turbidity currents in the Gulf of Mexico. Most agencies use models to address practical applied problems, for example: operational forecasts; regulatory assessments, permitting, risk assessments, remedial action plans, emergency response, and outreach to stakeholders. They rely on models developed or are funded in-house, for reasons of quality control, specificity, familiarity (with the developers, agency users, and contractors), and cost of changing. Still, the CSDMS community and its products might offer agencies coupled models that these same agencies might like to see developed.
As a proof of concept, and with support of the Marine Working Group, CSDMS will help couple a high resolution large-eddy-simulation (LES) turbidity current model to a coarser resolution Reynolds-averaged Navier-Stokes (RANS) ocean circulation model ROMS with the Community Surface Transport Model enabled. This LES-RANS model coupling will employ CMT and also couple with other data and model components. The project is funded through a Rutgers University cooperative agreement with the Bureau of Ocean Energy Management (BOEM), and CSDMS will use this opportunity as a proof-of-concept at getting academic (research grade) models into an operational workflow.

About Interoperability Initiative

__NOCACHE__
Goals
Welcome to the CSDMS Exploring interoperability of open modeling platforms initiative page. The goal of the Exploring interoperability of open modeling platforms Initiative (currently members) is to make models interoperable between modeling platforms. Open modeling platforms (e.g. CSDMS, OpenGMS, HydroShare) are increasingly emerging to encourage scientists to apply numerical models for their research. Through these platforms it becomes easier to run models in a stand-alone or coupled configuration. To do so, models are configured or wrapped according to specific platform standards. However, each open modeling platform has its own set of standards. This new initiative is proposed to explore interoperability for open modeling platforms to enable resource exchange. Technical issues include designing model standards and specifications that can be used across different platforms, developing a generic wrapper on top of the existing wrapper under one generic platform, etc.

About RNMI Initiative

__NOCACHE__
Goals
Welcome to the CSDMS River Network Modeling Initiative page. The River Network Modeling Initiative (currently members) develops and applies modeling tools for river channel evolution, including sediment supply and transport. The initiative supports applications in basic and applied research and on timescales of <1 year to geologic timescales. While raster-based landscape evolution models and single river profile morphodynamic models are common, network-based approaches for sediment transport and channel evolution are comparatively rare. Yet this type of representation is better suited for fluvial sediment transport processes.
Initiative products include the Landlab NetworkModelGrid and the NetworkSedimentTransporter component. Ongoing work seeks to expand modeling tools, example applications, and trainings. Specifically, we aim to:
* Create a suite of generalized tools and tutorials to enable widespread use of network-based sediment transport and river channel evolution models among the surface process community.
* Compile synthesis examples that either showcase capabilities of initiative products in the context of real-world examples, or highlight infrastructure needs.
* Improve the coupling between 2D mesh and network models.
* Foster community among groups and individuals working on sediment pulse and landscape-scale fluvial sediment transport modeling via workshops and hackathons.
We welcome engagement from all interested individuals and groups.

About Terrestrial WG

__NOCACHE__
Goals
The Terrestrial Working Group (currently 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.

Abstract AAPG 2010

Vertical change in a delta’s surface relative to local mean sea level, DRSL, is determined by five factors:
 DRSL = A - DE - Cn - CA ± M. 
A delta’s Aggradation Rate (A) is determined from the volume of sediment delivered to and retained on the subaerial delta surface as new sedimentary layers, and typically varies from 1 to 50 mm/y. Dam interception of upstream river-borne sediment presently leaves modern rivers with relatively clean water, reduced flood magnitude, discharged within fewer distributary channels armored with artificial levees. Flooding from ocean surges can sometimes contribute turbid water. DE, the Eustatic Sea Level Rate, is influenced by fluctuations in the storage of terrestrial water (e.g. glaciers, ice sheets, groundwater, lakes, and reservoirs), and fluctuations in ocean water expansion due to temperature. Today DE contributes 1.8 to 3 mm/y under the influence of global warming. Deltaic shorelines are experiencing extraordinary rates of relative sea level rise due to non-eustatic forcing. Natural Compaction (Cn), or Accelerated Compaction (CA) reduce the volume of deltaic deposits respectively through:
* dewatering, grain-packing realignment, and organic matter oxidation (typically ≤3 mm/y); and
* subsurface mining (oil, gas or groundwater), human-influenced soil drainage and accelerated oxidation.
CA can exceed Cn by an order of magnitude. M is the typically downward vertical movement of the land surface as influenced by the redistribution of earth masses (e.g. sea level fluctuations, growth of delta deposits, growth or shrinkage of nearby ice masses, tectonics, and deep-seated thermal subsidence). M is highly variable spatially but rates are typically between 0 and -5 mm/y. A majority of the modern deltas are now sinking at rates many times faster than global sea level is rising. Categories identified include those where:
# Reduced aggradation that can no longer keep up with local sea level rise (Brahmani, Godavari, Indus, Mahanadi, Parana, and Vistula);
# Reduction in aggradation plus accelerated compaction are overwhelming global sea level rise rates (Ganges, Irrawaddy, Magdalena, Mekong, Mississippi, Niger, Nile, and Tigris); and
# Delta aggradation has ceased and/or anthropogenic compaction is very high (Chao Phraya, Colorado, Krishna, Nile, Pearl, Po, Rhone, Sao Francisco, Tone, Yangtze and the Yellow).
