Hi All,

i am trying to add rivers to the model. I did arrays identical with grid and in 6 points are values of mass flux (kg/m^2/s). I use real and reasonable data where incoming volume is about VOL~2000 m^3/s. I recalculated this value to mass flux (kg/m^2/s) using equation:

M_FLUX = VOL*density/area_of_the_cell.

When i started the model i got negative salinity values in the place where are the rivers. I have tried to split this volume into more cells and it helped but during the spring outflow i have got negative salinity again. The model treat the river as a sfwf, does anybody tried to apply horizontal velocity of this flux.

Volume of 2000 m^3/s is not huge but some river can have up VOL~280000 so i afraid if i will divide it into more cell i will no be enough.

Thanks,

Jaromir
