Using SLAMM / Re: Latest Versions of SLAMM
Last post by Jonathan S. Clough - June 21, 2017, 03:05:16 PM
We're up to Build 239

Editable Max Fetch for Marsh -- Marsh horizontal erosion rates will now be applied when this editable marsh fetch has been exceeded for each marsh cell (previously this was hard-wired at 9km and this value will be loaded into older SLAMM6 simulations.).  This may be edited on a subsite by subsite basis.  This parameter is not relevant if the wave-energy erosion submodel is being utilized.

Also the "Last year of simulation variable" is always utilized even if "run specific years" is selected.  The interface was modified to make this more clear.

Now on GitHub https://github.com/WarrenPinnacle/SLAMM6.7

Editable Max Fetch Threshold for Marsh Erosion -- Marsh horizontal erosion rates will now be applied when an editable marsh fetch has been exceeded for each marsh cell (previously this was hard-wired at 9km and this value will be loaded as a default into older SLAMM6 simulations.).  The threshold may be edited on a subsite by subsite basis.  (This parameter is not relevant if the wave-energy erosion submodel is being utilized.)

We meant to add this as a feature of SLAMM 6.7 initially, but got so caught up in the new fancy wave power formulation that we forgot to modify the basic model.

Also -- the "Last year of simulation" variable is always utilized even if "run specific years is selected."  The interface was modified to make this more clear.

Using SLAMM / Re: Storm Surge Raster?
Last post by Jonathan S. Clough - May 04, 2017, 05:01:32 PM
Have you examined the users guide?  The input required is cell-specific flooding heights in units of NAVD88.  If you only have current storm surge height SLR will be added to it.  If you have SLR-specific maps those can also be accommodated though the file naming convention is rather inflexible.

What is your specific question?  Probably it would be best to start with the storm surge data that you have available and consider how to process that into the required raster format.

Using SLAMM / Storm Surge Raster?

I was curious if anyone has used this feature during model running? If so, how did you go about the creation of the raster? I noticed WP used something similar on their NROC project.

Hi Jonathan,

I am not sure what you mean by optimization? Is it the "track all cells" checkbox? If so, I did that and still, it gives me "999" No data for the dry land cells. I tried to convert blank to dry land and it would not track that either. One small success was filling the cells with upper dry land, even though received no elevation data. I've attached the pre-fill image here.

More recent NWI shapefiles do not specifically identify dry land; dry land registers as "no-data" in the NWI dataset (as it are not wetlands!).  (Historic data sometimes used the "U" designation for upland.)

Because of this, dry land needs to be manually added using the "turn blank to dry land" button.  For that to work, optimization needs to be turned off in the file setup window.  Also elevation data need to be present as it is how the model discerns dry land from open water when adding dry land.  Another option is to use the "fill cells" feature, but dry land usually bleeds into open ocean in that case.

Hope this is helpful -- send a screen capture or more information if not, please.  Best -- Jonathan

Thanks for the reply Marco.

I think what I meant was, do I need to add a cell into the NWI/SLAMM table to denote dry land much like I would do for any missing wetland class types? Does that make sense?

I am not sure I have completely understood the question.

If you have already a land cover layer with dry land cells then the problem may be in the elevation layer.

If your land cover layer has blank cells in the dry land portions, then the problem may be that you have some optimization selected in the File Setup window. First, you have to select "Track all cells" in the File Setup window. After loading the map you should be able to see the elevations in the blank cells and then convert blank to dry land. After saving the new land cover layer with filled dryland you can select again the optimization you desire in the File Setup window.

If you do not solve the problem, probably it would be best to have a look at the elevation and land cover layers.

Using SLAMM / Issue registering elevation of...
Last post by pse1999 - April 17, 2017, 03:21:47 PM
I was just curious if anyone could help with an issue I am having in SLAMM reading elevations on the dry land portions of my Study Area. It appears that whenever I hover over it, it reads "999" which is essentially no data. Is there something I have to do to the crossover table or to one of the input layers? Turn blank to dry land doesn't appear to be effective either.

Thanks in advanced!

SLAMM 6.7 is now on GitHub!

https://github.com/WarrenPinnacle/SLAMM6.7

Build 236 is now available with a few minor bug fixes:


  • Connectivity to inland-open water was inadvertently considered equivalent to connectivity to tidal water.  That has been corrected.

  • Conversion from SLB files to ASC files was fixed



The 64-bit installer is here:  https://github.com/WarrenPinnacle/SLAMM6.7/tree/master/INSTALL
