I am trying to figure out how big my pipes need to be for a storm sewer that I already have set elevations for. Every time I input the pipe and rim elevations for the network in the data tab it changes the inputs back to saying design. How do I set my own elevations for the pipe network?

I am having issues with importing / updating existing storm network.
The problem is when I update the storm network, All the outlets are added as new structures. It does not update the existing headwall / end sections.
I then have to go thru and delete the added (null) outlet structure. Then, reattach the existing outlets to the pipe network to show up in the structure data table correctly.
I have set the migration defaults to my part list and the pipes come in as expected but all the structures come in as null? I even went as far as setting every option to my rect junction NF and they still come in as null? What did I miss?

View 5 Replies View RelatedI am working on modeling a pond riser. I had one model with a series of small round perforations in the riser and I needed to look at a version that used larger, square cut-outs in the riser. So, I performed a "save-as" and adjusted my orifices to match my new model requirements. When I attempted to run the model, I received the following error: "ERROR 537 : Unable to perform multiple storm analysis, no storm was selected.".
I have encountered this one time before and was able to go back to the first model and start over. However, now, even when I run the first model (small round perfs), I receive the same error.
I have a storm event assigned for both models but the program does not seem to recognize this any longer.

I need creating a view up a storm pipe. We had the inside of a large diameter pipe scanned. Now I need to be able to create a view looking directly up the pipe. Is there a way to set the view so that the what I am seeing is the view from the center of the downstream end of the pipe looking to the center of the upstream end of the pipe?

See jpeg below.
I have set up a table style to display the type of structure, top of casting, and invert in and out elevations. I have also added a column to display the depth (rim to sump height). When the structure is a headwall, no depth is needed; however, the table displays this data as "???". Is there a way to only show depths greater than zero within the table editor for rim to sump height?
View 2 Replies View RelatedI have a storm crossing shown on a road profile, and the ellipse that represents the storm pipe is only showing part of the inner wall (I've attached an image). This pipe is skewed slightly, but the entire pipe crosses the road alignment, and this should not make any difference.
Also, is there any way, yet, (I'm using C3D 2011) to have the label show not only the pipe name, but also the invert where the pipe crosses the road alignment, and remain dynamic,? In other words, without having to edit the label text, and lose the dynamic capability. Land Desktop would do this, but it was not dynamic, of course.

I need to model a diversion manhole in a storm sewer system. The diversion will take X cfs from the system and send it to a water quality treatment facility. After leaving the WQ facility, it will be returned to the storm sewer system at the next manhole downstream.
I tried in Hydraflow but it doesn't look like diversions are possible. Thought about modeling up to the diversion manhole and taking that data into some other program, and then coming back into a second Hydraflow model that handles the downstream bit.
Typically when we have station offset for a storm structure shown to center of structure. How do you handle station offset with a storm structure label for say back of curb.

I have recieved a survey and I am now ready to begin my design. BUT, when I try and create a "pipe network", I am unable to connect the plan view with the profile. I have everything on both the plan and profile (water, sanny, gas, cuvlerts, etc etc) which was provided by the surveyor.

As I know we can import and export storm and sewer pipe lines between C3d and SSA. But how about open channels? I am workin on a project which is contain sewer pipes (close sections like circle pipes) and open channels(maybe as corridor in C3d) and some ditches with irregular sectios. it is pretty easy to define assemlies for open channels and ditches in C3d but if we can not pull the in SSA in order to analyze then we need to do the job twise in both software. I've tried to pull my network into SSA. but it just import pipe networks not open channels. is there any way to import them or any other software that can import from C3d and analyse the network?
View 4 Replies View RelatedI tried to open the Storm and Sanitary Sewer analysis program and got an error message. The error message asked me to send a report but the report was rejected.
View 8 Replies View RelatedIn Civil3d 2012 when the Edit in Storm and Sanitary Analysis command is used to send a Civil3d pipe network and Catchment areas to SSA the program appears to open as expected with the "Create New Project" dialogue box displayed.
When the Create New Project prompt is accepted nothing is displayed in the SSA plan view.
But.... If I go to the SSA File pulldown menu the .spf project file is available and when it is selected a dialogue box is displayed indicating that the Background file(the dwg) file cannot be found and do we want to search for it "Yes/No".If No is selected the pipe network is displayed as expected.
If Yes is selected and the dwg file located and selected then the pipe network is displayed as expected but the background file looks like proxy objects.

I have a client that wants to put in a constant flow into an inlet and have SSA calculate the HGL downstream of that (as well as add additional flows at additional inlets). Is there a way to do this? I tried adding an "Initial flow" to a pipe but after running the analysis, that flow wasn't the peak of the pipe (I used 1cfs for the initial flow and the peak was 0.77 cfs).
View 6 Replies View RelatedI am modeling an existing storm system that is under capacity. After running the model, some of the flows seem to be incorrect. I have one section that has a known flow of 1.31 cfs. The results for this pipe section shows 28.82 cfs (peak flow during analysis) and 6.06 cfs (design flow capacity). The pipe section is a 15" with constructed slope of 0.0088 ft/ft. The max velocity attained is 23.48 ft/sec. I know that the downstream is undersized. Could this flow rate be caused by the downstream backflows? The model is setup as hydrodynamic and rational method. My inertial terms are set at ignore, time step = 0, junction surface area = 0 and variable time step with safety factor 75%. I have gutter bypass flows and my sag structures have ponded area set at 100.

View 9 Replies View RelatedI have a huge subdivision that we are about to do in civil 3d. The subdivision has over 1800 lots. I am wondering what is the best way to go about this. At the moment we are thinking we have to do the alignments, profiles and corridors all in one design drawing for it all to be dynamic? If so this file is going to be huge. Is there a way we can split it up and still keep everything dynamic?

View 1 Replies View RelatedI have a simple catchment area that I've routed to an inlet and then to an outfall. The 10 year storm peak flow going into the inlet is 3.91 cfs and my flow in the link to the outfall is 10.55 cfs. I do not understand why it is increasing going into the pipe. I've attached the pdf results here because for some reason it won't let me attach.spf file.
View 4 Replies View RelatedI can't figure out how to reverse the flow direction on my pipe so I was going to just redraw it but after I delete a pipe and rt click to edit network the "add pipes and stuctures" won't let me add anything. I'm just guessing I need to reverse the flow direction because my invert out and invert in elevations are backwards in the profile. I'm working in Civil3D 2012.
View 6 Replies View RelatedI am wanting to get the peak flow back into Civil3d to add to our long sections, I assume the Peak Flow in SSA is the Flow rate property for the pipe in Civil3d, the HGL stuff seems to come in ok.

Pipe network storm pipes: Fairly new to Civil3D and trying to set up parts list for the storm sewer pipe and would like the plan view to appear as it does currently. We use a polyline for centerline of pipe, similar to dashed linetype but line and space are the same, width set to pipe width.

View 5 Replies View RelatedI am modelling a steep channel of constant slope operating under super critical flow conditions between two small weirs. I have set up two different models to represent this:
1. A single link between the upstream and downstream weirs.
2. I have also modeled the channel as a number of smaller links with the same slope separated by nodes spaced arbitrarily along the channel length.
The two models give very different results. The former results in an unstable channel (oscillates between sub- and super critical flow) and a maximum velocity in the channel of around 1.5m/s. It seems to me that the velocity in the upper section of the channel should be higher. I assume this has something to do with the manner in which SSA averages the velocities along the entire channel link.
The second model gives more realistic velocities in the upper channel links (around 3.6m/s) and a hydraulic jump and transition to sub critical flow upstream of the weir in the lower channel. This seems more realistic. I think the trick here is to make sure that the downstream link is long enough to enable realistic formation of the hydraulic jump in the model.
