DELWAQ offers intricate calculation algorithms that allow you for example to split up a measured value of total nitrogen into the modelled substances PON1, NH4 and NO3;deal with different location names in the input data and your model: you do not have to carry out cumbersome “search and replace” actions.

Thanks for your answer but my concern is that whether the calculation time will increase significantly if I include more processes and substances (for example BOD or algae)

DELWAQ simulation time approximation

I've set up an estuarine hydrodynamic model with Delft3D (rectangular grid) which I will use for D-WAQ simulation.
Specification:
+ Grid dimension 242x284.
+ Hydrodynamics time step: 0.2 min.
+ Simulation duration: 1 month.
For D-WAQ, I want to simulate DO, NH4, NO2, NO3.
I understand that how fast I can calculate the result is relative to PC spec (I7 9700K 3.7GHz , 32GB RAM). For me, the FLOW simulation took about 2 hours to complete (Single core).
My question is:
1/ How long would it take for me to run the simulation in D-WAQ with the minimum step of DelWAQ is 1-hour interval result? just approximation is good
2/ Would the computation time vary significantly (for one-month simulation just like hydrodynamics) if I include more processes in the D-WAQ besides these substances?
Thanks!
