Terrestrial
Terrestrial Working Group
Introduction
The Terrestrial Working Group 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 group last met on February 2-3, 2009. For more information about the meeting visit: Terrestrial WG 2009.

Greg Tucker earned a Bachelor's degree in Anthropology from Brown University in 1988. After working as a field archaeologist, he attended Penn State University, receiving his Ph.D. in Geosciences in 1996. After spending time as a postdoctoral research associate in the Department of Civil and Environmental Engineering at MIT, he served on the faculty of the School of Geography and the Environment at Oxford University from 2000 to 2003. In 2004 he joined the Cooperative Institute for Research in Environmental Sciences and the Department of Geological Sciences at the University of Colorado. His current research focuses on the dynamics of drainage basin evolution and the development and testing of numerical landscape evolution models. He is also interested in the statistical-physics underpinnings of sediment transport on hillslopes and in channels. He is an associate editor for the Journal of Geophysical Research--Earth Surface and serves on the editorial board of Earth Surface Processes and Landforms.
Announcements
The next meeting of the Terrestrial Working Group will be held jointly with the Marine Working Group and is being planned for October 26-28, 2009 at the CSDMS Integration Facility in Boulder, Colorado. A tentative agenda will be posted in the next couple of weeks. If you are interested to attend, please contact either Working Group Chair.
