PondPack V8i - 0 Flow for a post development scenario

I need to generate a hydrograph at a POI for a pre- and post-development scenario for a typical 2-yr 24hr storm. When I obtain a hydrograph for my pre-development scenario it generates an appropriate hydrograph. However, when I try to generate a hydrograph for my post development scenario, it does not generate a hydrograph at all. It shows a flow of 0 ft^3/s for the entire duration. I don't understand what is happening, as I have the correct storms in my "Global storm data" and from what I understand, they should be applied to all scenarios.

I am fairly new to this program and have gone through most of the tutorials on Bentley's LMS, but I cannot find a solution to this specific question.

In addition, is there a way to generate a combined hydrograph of lets say a pre and post 2 year storm event at a specific POI?

Thanks,

Tim

  • Hello Tim,

    We may need to see a copy of the model to look into this issue. There are two options for sharing your model files on BE Communities. If you would like the files to be visible to other members, compress the files into a zip file and upload them as an attachment using the ‘Advanced Reply editor’ before posting. If your data is confidential, you can follow the instructions in the link below to send it to us via Bentley Sharefile. Files uploaded to Sharefile can only be viewed by Bentley.

  • Hello Tim,

    For the results, all of the outfalls appear to have hydrographs. One outfall (POI E) is not connected to an active element and has no data at all. If that was the element in question, make sure the catchment connected to it is active. Otherwse, was there a specific location where you are not seeing results?

    As for the question on viewing the pre- and post-development hydrographs for a given element, that is possible as long as both scenarios are computed. Once both are computed, create a graph for the element you want to view. For instance, right-click on POI D and choose Graph. In the Graph Series Options dialog, look a the Scenarios section all the way to the left. Select the scenarios you want to view, such as the "Pre- 2 Year" and "Post- 2 Year", then click Okay. A graph with data for both scenarios will be displayed on one graph.

    Regards,
    Scott
