Hello,

I am running a model for a large lake, there is recirculation, aeration, outflow for irrigation, and inflow of urban runoff. When I run the model I get the error “ABORTING RUN DUE TO TOO MANY NEGATIVE DEPTHS” as seen bellow.

After reading the other topics relating to negative depth, I changed the time step and ensured the water depth was accurate however I still get this issue. what is the cause of this issue and how do you fix it?

Thank you for your help,

Hello jpenderghast
Usually, these issues will be related to the time step, but there are some cases also due to incorrect settings or model inputs time series, if you changed the time step and still get this issue I think you can send me the model I will check it more carefully below is my email address
