Join Josh Modglin for an in-depth discussion in this video Size drainage network, part of InfraWorks 360 Essential Training.
- [Instructor] Once we have the inlets located and placed in our design, the next step of our design is sizing our drainage network. So you see our drainage network drawn on our roadway, and we see the different structures that come together to the manhole, and they flow out, but everything kind of is just keeping the minimum cover and the other parameters. What we're going to do is I'm going to come up, I'm in the size network proposal, I'm in the engineering view, and I'm going to change, or better yet, I'm going to add a new proposal called size network end.
And I'll be working in this proposal, I'm going to select the road, and I'm going to right click and under drainage one of the other options was to size the drainage network. So once we've added the drainage network, we can size it. I'm going to choose size drainage network, we're having a little bit of an issue with an outfall, we can catch that after, we're going to continue with our design. And it comes up, and again just kind of check some of those parameters, what is our minimum cover, how much fall do we have across the structure, what is our material for our roughness, and do we want to hold an outfall.
In this case we're going to say no, that way we have a little bit of control for our minimum cover and that we can work with our design a little bit better. We also want to set what is our year, so we're going to design to the 25 year rain event, and we're going to not use BDE, but the rainfall content that we had created earlier on with our settings exercise. We're going to use Georgia IDF, and notice down here it says press enter to size once we've gotten all our values.
So it's going through and sizing all of our pipes, all of our structures, it's getting them all located, and it's not just sizing the pipes, but it's also changing inverts and elevations throughout these structures so that they're more appropriate for our design. So it's kind of the next step of our design, as you see now, the pipes come in and you see that drop that we have in this structure to deal with proper sizing of the pipes and the design of the system itself. So again, the software is accomplishing much as we go through and set these parameters, and we simply have to make sure the information we feed it is accurate, and it gives us a very good preliminary design to proceed with.
