Join Josh Modglin for an in-depth discussion in this video Culverts, part of InfraWorks 360 Essential Training.
- [Instructor] Now that we've created our watershed and we've looked at the settings for that watershed to get it in the correct method and settings, we clearly know where we need to put a culvert. So let's go ahead and start with our drainage design. And so we are going again to our design, review, and engineer drainage. And in our flyout we're going to choose to design our drainage. And of course we have lots of different tools that are available for designing our drainage. Now before we proceed, notice I'm in the Culvert_Start proposal.
We're going to add a new proposal based from the Culvert_Start and we'll name this Culvert_End. And now we'll go ahead and design our culvert. So we'll go ahead and select culverts, it says add the culverts. We're going to add a culvert form this point to this point. And once I pick it, it's going to generate the culvert and it's going to size it for us. It will show us the design of the culvert as well, the upstream and downstream values, and we can make adjustments to that after the fact.
So let's come down to our culvert, and I'll hit escape because I'm not adding any more. And notice we have some different tools that we can make the adjustments. So you see the different grips. We've gotten used to these grips. And we can of course adjust how many barrels we have, we can look at the different settings. Right now we have a culvert size of 114 inches to handle all the water from the watershed. Now we're going to slide the entrance of the invert, the downstream and the upstream, just in a little bit.
And of course you can make these adjustments as you see fit. You have the retaining wall, or the head wall I should say excuse me, for your culvert as well. But notice how it continues to keep the analysis results open or up. And you can even see what your HGLs going to do in that culvert. Now you can always turn that off so it's not showing, but I think it's very useful as you're working through this design. So one of the things I see is it may be useful to have two barrels, so I'm going to change to one barrel culvert to two barrel culvert.
And we see the size immediately dropped 20 inches, and makes it a little bit easier to work with. So we're going to slide this back a little bit. We can always make adjustments as well to the height of our head wall. We can change the flare angle, maybe that's a bit much for us. So we can do all these different things that will regenerate at every value that we've changed with these cards. I'm going to just slide it again a little bit farther back. Now as I slide it back, it makes a difference on what I'm grabbing here.
Make sure you grab the correct one and when you do grab that correct red box ... Remember the red box, or the purple magenta box, depending on if it's active or not, you have control over the x, y, and the z. So be cautions and make sure that you get the invert elevations correct, as you slide it up and down and left and right. And so notice I'm a little bit high here, and so I'm just going to continue to get that value to something that is more realistic and works with the flow that I need to accomplish.
And so that's a little bit closer to what I'm aiming for. I go to the other side, and I may do the same thing, slide it back a little bit, and into that slope. So you can continue to make your adjustments to the design itself, as you do every single time you make those adjustments you'll see that it shows the values in analysis up above your culvert design.
Now if you look at the culvert design again, it's provided a good design but my HGLs seem still a little high, and almost running at pressure. So I'm going to change that here, and we're just going to go to maybe a box shape, and make the adjustment as well. So there's a lot of different things that you can do with your design, but as you make these adjustments to your design, every single time you make these adjustments, it's going to rerun analysis for that culvert. It's going to give you information about that culvert, and of course you can make the adjustments in the graphic of what that culvert's going to look like as well.
So we're creating a design that not only is accurate but provides very real time visual analysis back to us, where we can even create a report and define the preliminary design of this culvert.
