WAQ-Mass Balances- zero contribution of Bo+Lo

2023-01-16T08:36:35Z

Hello,

I run a basic WAQ pollution scenario in a marine area (no tide). The .hyd file is created by FLOW and basic processes are loaded via the .sub file. Boundary conditions are set as time series and discharges are set in the plot area (constant in time)-both manually. Atmospheric deposition occurs as well-set by a segment function file. Results look normal and logical (.ada file), with the contribution of the discharges and open boundaries visually seen in all output files. Despite that, in the mass balances output file (.prn), the contribution of open boundaries and waste loads is zero for all pollutants, which is not what I expect. I attach an image.

Cd _dAtmDepCd 0.14935E+04 0.00000E+00
SUM OF ALL TERMS 0.29054E+08 -0.29054E+08

I use Deltares, Delft3D-WAQ GUI, Version 4.00.00.57433, Aug 16 2018 to create the scenario and Deltares, DELWAQ Version 5.06.00.7094, Mar 29 2017 to run the simulation.

Thanks for any suggestions that may lead to resolve this!
