Webinar: Marshes on the Move (NOAA)

NOAA Digital Coast webinar series presented Marshes on the Move: A Manager’s Guide to Understanding and Using Model Results Depicting Potential Sea Level Rise Impacts on Coastal Wetlands which was held on Wednesday, December 7, 2011. Presenter(s): Nate Herold and Nancy Cofer-Shabica, NOAA Coastal Services Center; Adam Whelchel and Roger Fuller, The Nature Conservancy. The scientific community is generally in agreement that global sea level is rising and coastal marshes are changing as a result. Understanding where and how coastal environments will change in response to sea level rise, however, is a complex modeling challenge dependent upon many factors. This webinar will help participants understand key considerations and questions to ask when presented with models and maps estimating the future condition and location of coastal wetlands in response to rising sea level. In this webinar, participants will gain a basic understanding of some key parameters and uncertainties associated with these models; hear from technical specialists regarding real world implications of model results; and learn how to more effectively incorporate modeling results into management initiatives.

SLAMM 6, Official Release

The SLAMM 6 model supports time-varying feedbacks to the vertical accretion of wetlands. Feedbacks based on wetland elevations, distance to channel, and salinity may be specified along with a time-variable turbidity factor. The salinity module has been rewritten and improved but remains fairly simple. The SLAMM 6 graphical interface has been significantly redesigned including OpenGL 3D mapping. Wetland elevation-range parameters have been brought into the model interface and the model is considerably more flexible in this regard. Elevation and salinity by land-cover statistics are automatically produced. SLAMM 6 includes a command-line mode to support externally driven sensitivity and uncertainty analyses. For more information about this release, and how to obtain the model, please visit this SLAMM Forum thread. For questions and comments about the SLAMM model please utilize the SLAMM Forum.
