We are using SLAMM version 6.7 and wanted to make sure the following holds on this version:
this version considers historical SLR rate or Uplift/Subsidence raster and marsh accretion rate in order to calculate the marsh elevations in relation to sea level as explained in Accretion or surface elevation change. So, it means the elevation output of SLAMM incorporates both these rates in marsh area and the first rate (historic SLR rate or Uplift/Subsidence raster) in open water and upland area?
unlike mentioned on Elevation output, the elevation output is converted back into NAVD88 on this version?
We are working on a large study area and are thinking of making use of High Performance Computing (HPC) cluster that we have in campus. The operating system in the HPC is Linux. So, we need to compile SLAMM on Linux. I wanted to get some idea about the possibility of using SLAMM in Linux before I start digging into the Delphi compiler in Linux. Has anyone tried SLAMM on Linux? What would be the best approach to get started for it to make it work?
We are having an issue with Erosion in SLAMM that we are running in Galveston Bay. SLAMM is not triggering marsh and beach erosion in areas where wetlands are adjacent to water and the maximum fetch threshold is reached. We ran a sensitivity analysis varying erosion rates (marsh, swamp, and tidal flat) by +/- 15%, which resulted in no change to model output from the base case. Following the post in SLAMM forum, we attempted to force SLAMM to trigger erosion by converting the Estuarine Open Water class to Open Ocean since SLAMM will assume max fetch is infinite when the last cell on the edge of the map is Open Ocean, but erosion still isn't occurring. Similarly, we also tried to run the model with the reclassified water and run the sensitivity analysis with the reclassified water, but it also does not make much difference. We wanted to make changes on SLAMM code to see if decreasing the fetch length from 9 km may be useful. Can you please point me to the place in the code where I can make changes to it?
