PondPack User Notification concerning Peak and Allowable Flows

thomas_downer

Upon running a Modified Ration Method analysis, I am getting the Error Notification below and cannot figure out exactly what it means by the Allowable Flow and how it is computing this value, it does not correlate to any calculations I've done by hand.  Any ideas on how to fix this?

Any help would be greatly appreciated.

Thanks,

    Sorry, the screen capture did not come out.

    The Error Notification reads: 

    Message ID:  -1 

    Scenario: Pre-Development 100 Yr. 

    Element Type:  Catchment 

    Element ID:  31

    Label:  DA-1

    Time (hours):  N/A

    Message:  The flow (peak), 24.85 ft³/s, is less than the flow (allowable), 32.91 ft³/s.

    Source:  Engine Fatal Error

    I managed to find the issue and fix the problem. For some reason, if I create a new Hydrology Alternative and associate it with a previously created Scenario, it will duplicate my Pre-Development C/Area values and also my Pre-Development Tc collection values multiple times, giving me erroneous calculations. I have to physically go in and delete the duplicated values.

    Hi Thomas,

    I spent a few minutes trying to reproduce the issue you describe in PondPack 08.11.01.56 and was not able to. Are you able to provide a copy of the model along with steps to reproduce the duplication you described?

    Jesse,

    I'm going to go back through the model again today and see if I have the same results (issues). If so, then I'll post a zip file with the model and the steps immediately leading to the duplication.

    Thanks.

    I'm looking at my alternatives and they are as usual. However, there are duplicated values in my Catchment Properties. I uploaded my model to this thread for you to take a look at, and  below is a screenshot of what I am seeing:
