Upcoming Workshops

Chesapeake Modeling Symposium 2016

Symposium Theme - "Chesapeake Challenge: Advancing transparency and communication through community modeling."

We will be updating this page frequently so check back soon!

Numerical models are used extensively for marine research and also to guide management efforts in Chesapeake Bay and around the world. Many of these models are very complex. For example, the Chesapeake Bay Program modeling system is composed of a set of sub-models of the airshed, watershed and estuary and it also includes living resource components such as submerged aquatic vegetation, oysters and fish. Each of these sub-models consists of a complex system of equations that have been developed implemented by experts in each field. Combined, the CBP modeling system is too complex for one person to fully comprehend, yet we have to rely on this system to guide crucial management decisions that directly impact numerous stakeholder groups. One way to increase the transparency of complex models is through the use of open source and community modeling approaches that allow direct access to the code and encourage broad participation in the model development process. But these approaches create some significant challenges and they do not address the issue of how to increase transparency with stakeholder groups. For the latter we may need to employ new participatory modeling methods that directly engage stakeholders in the model development and/or application process.

By bringing together modelers, managers, scientists, and stakeholders for a series of plenary talks, panel discussions, and special sessions, the 2016 Chesapeake Modeling Symposium (ChesMS16) will focus on the challenge of increasing communication and transparency in the model development and application process through open source, community and participatory modeling.


Prior Workshops

Chesapeake Modeling Symposium 2014

Symposium Theme - Chesapeake Frontiers: Modeling the Watershed,Estuary, Living Resources, and the Socio-Economic System

Environmental models are increasingly taking on higher profile roles in the management process. Numerical models have been used extensively to guide management efforts in Chesapeake Bay. These models include simulations of the airshed, watershed and estuary and have included living resource components such as submerged aquatic vegetation and fish. Although these models are some of the most advanced in the world, many challenges remain. These include the need for higher spatial resolution and better mechanistic representations of physical, biological and chemical processes in the airshed, watershed and estuary. More flexible approaches are also needed for representing management impacts on living resources and particularly higher trophic levels. Linking these models to human impacts and socio-economic systems is another challenge that has not yet been addressed. More flexible (modular) approaches could also facilitate the use of multiple models. However, the development of increasingly complex end-to-end models that are difficult to validate, understand and diagnose also points to the need to develop alternative simplified empirical and mechanistic models for specific management applications.

Chesapeake Modeling Symposium 2012

The 2012 Chesapeake Modeling Symposium will attempt to shed light on these emerging concerns and conflicts as they relate to regulatory thresholds and the environmental models that are used to set them, focusing on topics such as understanding, communication, and credibility. By bringing together modelers, managers, scientists, and stakeholders for a series of plenary talks, panel discussions, and special sessions, we hope to highlight the unique issues and concerns of each of these groups and provide a venue for open dialogue that will hopefully lead to greater understanding and adoption of these and other models.

CCMP Hydrodynamic Model Workshop

A joint CCMP, CSDMS, CBP, and US IOOS Modeling Testbed and Chesapeake STAC Hydrodynamic Modeling Workshop will be convened at the Smithsonian Environmental Research Center, June 9-10, 2011. The purpose of this workshop will be to review state-of-the-art coastal and estuarine hydrodynamic modeling and compare the strengths and weaknesses of different model grids and their ability to simulate physical properties such as temperature and salinity variability and stratification.

The agenda for the workshop is listed below.

Day 1

Day 2

Chesapeake Modeling Symposium 2010

ChesMS ‘10 was the second symposium convened by CCMP. ChesMS ‘08 was focused on highlighting and communicating new and innovative Chesapeake ecosystem open source models and building the existing library of available models and tools. ChesMS ’10 expanded on this by continuing to showcase new modeling efforts while also demonstrating how new and existing models can be applied to aid in Management, Research and Restoration decision support. By bringing together the model developer and user communities at the symposium, we fostered greater intra group understanding and communication. This will lead to a more product focused model development and a more intelligent use of these models. learn more, visit the ChesMS'10 Symposium Homepage!

Chesapeake Modeling Symposium 2008

The symposium is intended to facilitate the development of an inventory of models and data sets, and stimulate collaborative research on data processing and modeling. The resulting inventory of modeling tools and data will be made available through the CCMP web pages, in attempt to stimulate cross-pollination across modeling teams and paradigms and encourage future community modeling efforts. It is our hope that this will lead to the development of more comprehensive and integrated modeling tools for the Bay and its watershed, as well as for other watersheds around the country. learn more, visit the CheMS'08 Workshop Homepage!


AD Model Builder Programming Course

CCMP hosted a programming course for the AD Model Builder (ADMB) in March, 2007. AMDB is a software tool developed specifically for non-linear parameter estimation, which facilitates efficient formulation of statistical models & more.

Chesapeake Models and Data Distribution Workshop

This is an exciting time to be working in the Chesapeake Basin environmental science. Over the past few months several major programs have been started which will transform our way of working in the Chesapeake. Community models and data access methodologies are being developed which will enable all Chesapeake researchers to significantly expand their capabilities. A common thread to many of these programs is the integration of systems across the whole Chesapeake watershed or bay. The scope of the programs will involve more collaborative work than ever before. We wish to hold an informational workshop at which the preliminary plans of these different programs can be shared and integrated.

The one day workshop will introduce the community to the various programs and provide a venue for sharing ideas and ambitions. This will be a small workshop, so prior registration will be required. Please request registration from

Ecopath with Ecosim (EwE) Programming Course -- August 28-31, 2006

The Ecopath with Ecosim (EwE) software is being redesigned and restructured. To introduce the user community of modelers/programmers to the newly redesigned software, the University of British Columbia is offering a short course on the programming/code underlying EwE. This course differs considerably from usual EwE Workshops, which usually focus on data and parameterization for running models built using the EwE software.

This programming course content will focus on the algorithms and programming structure of the code underlying EwE and training users to use the new structure and dynamic libraries to create their own modules and functionalities for the EwE software using Microsoft Visual Studio.

This first EwE programming course will be held in Annapolis, Maryland and is sponsored by the Chesapeake Community Modeling Program, the Lenfest Ocean Program, the Chesapeake Research Consortium, the Sea Around Us Project, and the NOAA Chesapeake Bay Office.

W14: Building a Community Modeling Culture

Overview: Everyone agrees and demands that their researchers should share methods, data and models more easily within their community and with outsiders. Why then, don't cooperative modeling communities arise spontaneously and grow vigorously? Modeling systems and the science behind them have grown out of individual laboratories, often communicating results only after extensive peer review and verification efforts have been completed. While this is laudable from the standpoint of the rigorous scientific method, it is contrary to what is desired to produce an open-source software system as professed by E. Raymond in "The Cathedral and the Bazaar". There are working examples of vigorous community open source projects and examples which are less successful.

Similar issues apply to education. How much of content and interactivity are we willing to share? How can education and research become an open source, shared experience?

This workshop will explore sociological questions of motivation and communication about the development of Community Modeling Systems.
