Boundary condition in DelWAQ, how to apply Neumann conditions

Youngling Posts: 6 Join Date: 6/16/19 Recent Posts
I am trying to run some water quality simulations with DelWAQ module. For several boundary conditions I plan to set Neumann conditions, however I could only find a way to specify constants or time series of values to the boundary. I wonder how I could set the boundary condition to a Neumann condition? Many thanks in advance.

Best,

Hi Chao,

Unfortunately there is no direct way that I'm aware of to apply a Neumann boundary condition in Delwaq. You would first have to calcluate the relation of each parameter outside of Delwaq, using scripting for instance, and provide the boundary as a time series.
