Dear Jonathan,

Thank you very much. I have tried your solutions, as well as tried the older version of Delphi (Delphi XE8 - I have used this one to modify SLAMM 6.2 without any problems), but I got another error related to overloaded. Please see the attached photo herewith. Do you know how to fix this problem? Thank you very much.

Dear all,
I need to modify some codes, but when I compile the project it said that (I used RAD Studio 10.3):

I did some searches on google but still couldn't find the address. Anyone knows this error please help me? Thank you very much.

Thank you Macro.
I think I may not increase tidal flat erosion rate as well change the erosion function of marsh to open water instead of tidal flat, this is not reality although this is a possible solution to manage erosion problem so far. I think the best solution is that marsh erosion rate should be taken into account within the tidal range rather than be adjacent to open water, erosion should be trigger under the effects of tidal (including SLR).

Hi Marco,

Thank you very much for your response.
Based on the technical documentation, "Erosion is only predicted to occur at a land-cover to open water interface... The marsh erosion parameter pertain to the interface between open water and regularly- and irregularly-flooded marshes as well as transitional marshes.", in my simulation, Irregular.Flooded Marsh is adjacent to Open Water. The obtained results show that Irregular.Flooded Marsh is always inundated and converted to Regularly.Flooded Marsh then converted to Tidal Flat (this conclusion is drawn based on the table 3, showing that Inundation occurs dominantly) even though I already set 0.14m, or 1, or even 10m for erosion rate of marsh, this also means marsh erosion rate is not taken into account. I did try many cases, moved irreg. Flooded marsh to higher or lower elevation and other positions, but it's still inundated and converted to Regularly.Flooded marsh after simulated. I'm wondering whether the problem is my input data or SLAMM because I've read a lot of topics related to this problem in the forum. Thank you very much.

PS: My DEM resolution is 1m.

Hi all,

I have a question about erosion and accretion rate. Are they (erosion and accretion) always taken into account no matter a cell is inundated by SLR or not, right? or they are only taken into account when a cell is inundated?

Thank you very much.

Ok. Thank you very much.

Thank you for your reply. So that means Tidal creek wont convert to any categories and it will be stable throughout the simulation, right?

Hi everybody,

I have an inquiry about Tidal Creek (Category #18 in SLAMM). I've read the SLAMM technical documentation, but I didn't find any information about the conversion of this category. It doesn't appear in the Table 3 (p. 40), so I don't know which categories it will convert to if eroded or inundated, and is it static?

Thank you.

Hi,
Thanks for your quick response.

Hi,
I know that SLAMM has 26 categories. Is it possible for me to add more categories or edit them?
Thanks.

Thanks a lot.

Thanks for your response.

I understand what you meant. However, my regional SLR scenario curve may be different with IPCC's one, and this scenario is for period of 2010-2100, so I cant use regional SLR scenario at the moment but IPCC's.
I'm a programmer as well, is it possible for me to recode the open source in order to take the regional SLR scenario into account?

Thanks

Hi everybody,

I'm using SLAMM for my study. I have an inquiry about SLR scenario. Is it possible for me to use another SLR scenario other than IPCC's? More specifically, I have regional SLR scenario (in Canada), it starts from 2010 to 2100 (of course my input data - NWI photo's date is 2012). However, SLAMM uses SLR scenario from IPCC and it starts from 1990 to 2100. So, what I want to know is that If I can use my own scenario and change the starting year (2010 in my study), because in SLAMM, they are fixed (the scenarios and starting date).

Thanks for your helps.
