Join Josh Modglin for an in-depth discussion in this video Settings, part of InfraWorks 2018 Essential Training.
- [Instructor] Now that we have our watershed created, let's look at some of the settings that we have available in our analysis. But before we make any adjustments, let's go ahead and create a proposal. Notice I'm in the EditWatershed_Start. And from there I'm going to add or create a duplicate proposal that we'll make some adjustments to. Edit Watershed_end. And then I'm going to go ahead and select my watershed and notice some of the adjustments we can make. We can change the color of the watershed just so that that specific watershed stands out.
If we want, we can also change the method. We're going to use Rational. And then, of course, we can enter some of the values for that method. So let's say Runoff Coefficient is .4, and we'll say that our 100 year Rainfall Intensity is three inches per hour. Now, we can continue to make adjustments to this, or we can bump it up. Maybe it really needs to be four inches per hour. But you notice that it immediately runs and provides us Peak Flows with our cfs below.
Now, another place that we may want to set up and have our information available for our drainage design is our Rainfall Content. Rainfall Content is very similar to Styles. So I'm going to go ahead and pick on Rainfall Content. Again, we are in the Design, review and engineer drainage flyout under the Analyze your model. I'll deselect the watershed so that the card goes away. And notice that we already, by default, have a few different methods of getting the Rainfall Content, that IDF curve, or if we choose to use a BDE curve to do so.
There's other methods as well. Now we'll just take the tabular, the IDF as a sample, and we'll create a duplicate. Notice we could add or start fresh or create a duplicate and as we have been in most cases, we'll create a copy and we'll call this GA IDF. And in here we're going to make some adjustments to the IDF curve. You can, of course, just pick inside there and make adjustments as you see fit, mainly, of course, from the information you have.
And as you make these adjustments, the different curve values will show up depending on what we have selected. Once you have that set up, it's available to you to run analysis and really set up and use against your drainage design as you proceed.
