Can anyone please explain about these two different errors as shown in the screen capture.
The user notification in the image you provided references catch basins that don't have subsurface elements attached to them. When flow enters a catch basin it will then be subsurface flow. If a conduit is connected to the catch basin, then it can convey that subsurface flow. Without the conduit attached, the subsurface flow will have nowhere to go. This is why the message states that the captured subsurface flows are lost.

If there are conduits attached to these catch basins, they will need to connect to an outfall to be "valid".
Make sure there aren't any overlapping nodes that create a disconnection in the network.
You can use Network Navigator to locate elements that are disconnected from the outfall.
To do this:
1. Go to View > Navigator
2. Click the ">" icon > Network Trace > Find Disconnected
3. For the "Find Elements Disconnected From" input field, choose "Select..." > click on the outfall element > Click OK.
4. The Network Navigator dialog will then list all elements that are disconnected from that outfall.
5. Click the highlight icon in the Network Navigator dialog to highlight all of the returned elements.
This should make it easy to locate where the disconnection is in the model.
The Network Navigator, Network Review query "Orphaned Nodes" may help as well.
The following article was written for the different products, but it does a good job at explaining how to use the tool and includes a video demonstration.
Using Network Navigator
Actually I connect that catch basin with gutter.
Also, I have hard my hard time to figure out some error in my model. Can you please help me to figure out.
There is flow in my gutter but it is not coming out from outfall and seems lost from somewhere.
I also insert some fake catch basins with percent capture 0.001 to start my gutter somewhere like GU16, GU 17 etc.
Are you saying the the flow results at the outfall are zero? Have you tried graphing the results to confirm if there is flow at other time steps?
The graph I mentioned can be ignored, since this is StormCAD.
I took a look at your model and this appears to be working as expected. The flow report at the outfall is flow related to channels or conduits. The gutter flow is still reported in the property field "Lost Surface Rational Flow".
I just wanna my model setup is good or not. Because I am getting high spread. I can only use up to 9.5 ft. When I used flow master with same data the spread is different and too low.If this model is working i will go for further design new sections.
Also, Once I rum automated design can I adjust the value manually? After adjusting I have to just analyse the network or I have re-run the design? I have four constraints velocity, cover, slope and spread, Is there any way to assign it in correct order because after assigning all constraints and set design inverts and pipe it gave random pipe slope to adjust constraints after design. I went through that guide "how to apply constraints " but it is still not working.
Please suggest me for my user notifications in my model, that is ok or still I have to correct it?
