CivilStorm

I have a catchment connected to an outfall node.  After running the model the report option outputs N/A for all results.  I was specifically checking to see if the catchment peak flow out matched the outfall node peak flow in.  The graph and data table options work as expected for the same outfall node, so it appears the model is working. 

Other outfall nodes connected to a conduit from a pond outfall do not seem to have the problem and report data as expected. 

Is there a solution to make the report function not output N/A for catchments connected directly to nodes?

  • Hello David,

    Could you provide a screenshot of what you are looking at, and your CivilStorm version number?

    If you are referring to the results at the outfall node element, results like hydraulic grade and depth cannot be calculated if there is no attached conduit, as there is no pipe geometry to base them on.

    The outfall "Flow (total out)" result should still be showing a value (and you should be able to graph flow as well), but if you are referring to the "Flow (out to links maximum)" result, this will show as "N/A" if there are no links (conduit or channel) adjacent to the outfall. If you simply have one catchment connected to one outfall, then you can look at the "Flow (maximum)" result. Otherwise, you will need to place a link element for the catchment to discharge to. For example if it discharges to a ditch, you could use a Cross Section node element > channel > outfall, with the cross section set as the catchment's outflow node.

    Also, make sure you have "Always compute hydrology?" checked.

    If this does not help, please provide your CivilStorm version number and a copy of the model file, with steps to reproduce:
