Applying different bed friction in the ADCIRC domain

[ahmadmukhlisfirdaus]

dear all,

Currently I'm using Adcirc on SMS Aquaveo for tidal energy modeling. I have problem in applying different bed resistance in the model domain. Based on Adcirc source code, I could applied it on fort.13 file. I used this method but I found that it is so difficult since I ave to track the node number one by one.

Anyone here know how to apply it in the model domain using spatial attributes? Or are there any other method to create fort.13 file in Adcirc?
