Re: Minus sediment concentration in river sediment case
Very strange!! ZQ told me to move river point seaward to see what will happen. I tried it, same abnormal salt result. However, I tried to move river point landward. Now the model runs nearly one month, the salt is good and the river flow into sea too. But this means I put the river cell in land. I ...

Re: Minus sediment concentration in river sediment case
Hey, I had run your model and I have got the same problem of negative sediment values but I got TS influence from one river. http://alunoca.io.usp.br/~coelho/temp/salt.png The thing is that your model domain is very huge. I don't know if this is really the problem but your Dx and Dy is 18 km. My sug...

Re: Minus sediment concentration in river sediment case
There are 3 kind of sand in my model. I just 2 kind of sand from rivers, the third kind of sand doesn't come from rivers. So I set river_sand_03 zero. I tried your new river forcing file and found that there is sand coming from the river. I tried my old river forcing again, and found there is also ...

Re: Minus sediment concentration in river sediment case
Seems that everything is fine. Try to put all the 20 levels of river_Vshape = 0.05(attached) and see if you find any sand coming from the rivers.
Your river_sand_03 is always zero. Is that correct?

Re: Minus sediment concentration in river sediment case
GET_NGFLD - river runoff XI-positions at RHO-points (Min = 3.40000000E+01 Max = 3.40000000E+01) GET_NGFLD - river runoff ETA-positions at RHO-points (Min = 7.20000000E+01 Max = 7.20000000E+01) The Min and Max values for XI-positions and ETA-positions are the same. Are you sure you are using two riv...

Re: Minus sediment concentration in river sediment case
The river is located beside two land points. Did you mean the river should not near to land point? But another river is located beside three land points, its concentration is positive. I mean that the river should be near to land point. I had some problems with rivers located not exactly beside a l...

Re: Minus sediment concentration in river sediment case
Did you check if your river is located beside a land point? Maybe the negative sediment values are because of that.
