Hi all,
I've been developing a model for Narrabeen Lagoon, NSW. It is a ICOLL system, i.e., the entrance opens and closes depending on alongshore sediment transport. The system has 4 creeks flowing in with freshwater and an oceanic boundary for tides.
In a 7 day test simulation, where I input (fake data) 1 m3/s inflow from each creek and 10 m3/s outflow from oceanic side. The initial elevation is zero. I tried this to see if the cells are drying when the water level drops.
When I pull the slf output file into Blue Kenue, and plot the animation of the DEPTH and SALINITY (for example). I can see that as the water level drops:
1. All cells are reporting some DEPTH values, so how do we know when a cell is dry?
2. A dried cell still maintains the last wet value salinity at that cell and doesn't go to NaN.
Am I doing something wrong here that the output can't be seen as drying and wetting again, i.e., in other models like FVCOM, when the cell dries, the salinity etc appear as blank cells by using masking.
Do I need to activate a minimum depth for the blanking of cells to start happening?
Or is there a output variable that helps mask dry cells (I haven't found one yet)?
I used:
TIDAL FLATS =YES
OPTION FOR THE TREATMENT OF TIDAL FLATS=2
/TREATMENT OF NEGATIVE DEPTHS=2
Any guidance would be appreciated.
Cheers,
Shiv
