Hello. The current project I am working on requires a fairly complex SewerGEMS model and I am currently getting a high continuity error. If any of the SewerGEMS experts could take a look at my model and point out some of the areas I need to review that would be very helpful. I will attach the model ZIP. In addition to the high continuity error, several of the catchments send an error message that the calculated peak is higher than the interpolated peak.
The area of the model I have been trying to get a better handle on is the plan North area that drains to Basin A. This model needs to contain a couple of upstream ponds and channels that ultimately drain to Basin A. I have noticed that the inflow graph for Basin A is incorrect and there is a large jump at 3hours into the model run. I have not been able to determine what is causing that jump.
The cross section where channel CH-02A and CH-13 merge also has an error I noticed. In the 2-YR Scenario, CH-13 shows no flow. CH02-A has a relatively small inflow, but after the two merge at CS-5 there is a large jump in the peak flow rate. I have not been able to figure out what is causing that.
If someone has some time to take a quick look at this model and confirm that the areas I have noticed to be problem areas are most likely to be the culprit for a good portion of this model error and offer suggestions on how to fix it would be much appreciated.
Thank you in advance.
