The topics to be covered include:. In this tutorial we will model the drainage system serving a 12 acre infoeorks area. The system layout is shown below and consists of subcatchment areas S1 through S3 A tutorail is an area of land containing a mix of pervious and impervious surfaces whose runoff drains to a common outlet point, which could be either a node of the drainage network or another subcatchment.
Storm sewer conduits C1 through C4, and conduit junctions J1 through J4. The system discharges to a creek at the point labeled Out1. Then we will simulate the water quantity and quality response to a 3-inch, 6-hour rainfall event, as well as a continuous, multi-year record. Using these defaults will simplify the data entry tasks later on. Next we will set some tutoriaal display options so that ID labels and symbols will be displayed as we add objects to the study area map, and ibfoworks will have direction arrows.
Finally, look in the status bar at the bottom of the main window and check that the Auto-Length Calculation feature is off. Also make sure that the Offsets option is set to Depth.
We are now ready to begin adding components to the Study Area Map.
Tutorial – Infoworks Documentation
We will start with the subcatchments. Remember that you can click the View Map button of this tutorial at any time to see how we want our map to look eventually.
Drawing objects on the tutogial is just one way of creating a project. The project file is a text file that describes each object in a specified format as described in the Users Manual. Notice how the mouse cursor changes shape to a pencil when you move it over the map.
Move the mouse to the map location where one of the corners of subcatchment S1 lies and left-click the mouse. Do the same for the next three corners and then right-click the mouse or hit the Enter key to close up the rectangle that represents subcatchment S1. You can press the Esc key if instead you wanted to cancel your partially drawn subcatchment and start over again. We will go back later and show how to fix this.
Then repeat for subcatchment S3. Observe how sequential ID labels are generated automatically infowork we add objects to the map. Next we will add in the junction nodes and the ingoworks node that comprise part of the drainage network.
Move the mouse to the position of junction J1 and left-click it. Do the same for junctions J2 through J4. To add the outfall node, select Outfalls from the Project Browser, click the. Note how the outfall is automatically given the name Out1. Now we will add the storm sewer conduits that connect our drainage system nodes to one another.
We will begin with conduit C1 which connects junction J1 to J2.
The mouse cursor will change shape to a cross hair when moved onto the map. Left click the mouse on junction J1. Note how the mouse cursor now changes shape to a pencil. Move the mouse over to junction Tutorual note how an outline of the conduit is drawn as you move the mouse and left-click to create the conduit. You could have canceled the operation by either right-clicking or by hitting the Esc key. Repeat steps 2 and 3 for conduits C2 through C4.
Although all of our conduits were drawn as straight lines, it is possible to draw a curved link by left-clicking at intermediate points where the direction of the link changes before clicking on the end node. At this point we have completed drawing the example study area. Your system should look like the one seen by pressing the View Map button above.
If the rain gage, subcatchments or nodes are out of position you can move them around by.
Select a vertex point on the subcatchment outline by clicking on it note how the selected vertex is indicated by a filled solid square. This same procedure can also be used to re-shape a link. As infowworks objects are added to our project, SWMM assigns them a default set of properties.
To change the value of a specific property for an object we must select the object into the Property Editor shown below. There are several different ways to do this. If the Editor is already visible then you can simply click on the object or select it tutoriak the Project Browser.
infowoeks If the Editor is not visible then you can make it appear by one of the following actions:. Whenever the Model Explorer has the focus you can press the F1 key to obtain a more detailed description of the properties listed. Two key properties of our subcatchments that need to be set are the rain gage that supplies rainfall data to the subcatchment and the node of the drainage system that receives runoff from the subcatchment.
Since all of our subcatchments utilize the same rain gage, Gage1tutorrial can use a shortcut method to set this property for all subcatchments at once:. To set the outlet node of our subcatchments we have to proceed one by one, since these vary by subcatchment:.
Type J1 in the Outlet field and press Enter. Note how a dotted line is drawn between the subcatchment and the node. Click on subcatchment S2 and enter J2 as its Outlet. Click on subcatchment S3 and enter J3 as its Outlet. Finally, we wish to represent area S3 as being less tutrial than the others.
The junctions and outfall of our drainage system need to have invert elevations assigned to them. As we did with the subcatchments, select each junction individually into the Property Editor and set its Invert Elevation to the value shown in the table below. An alternative way to move from one object of a given type to the next in order or to the previous one in the Property Editor is to hit the Page Down or Page Up key. Only one of the conduits in our example system has a non-default property value.
This is conduit C4the outlet pipe, whose diameter should be 1. To change its diameter, select conduit C4 into the Property Editor and set the Max. Depth value to 1. In order to provide a source of rainfall input to our project we need to set the rain gage properties.
Select Gage1 into the Property Editor and set the following properties:. As mentioned earlier, we want to simulate the response of our study area to a 3-inch, 6-hour design storm. A time series named TS1 will contain the hourly rainfall intensities that make up this storm. Thus we need to create a time series object and populate it with data. Having completed the initial design of our example project it is a good idea to give it a title and save our work to a file at this point. The project data is saved to the file in a readable text format.
You can view what the file looks like by selecting Project Details from the main menu. To open our project at some later time, we would select the Open command from the File menu.
Before analyzing the performance of our example drainage system we need to set infowogks options that determine how the analysis will infowprks carried out. We are now ready to run the simulation. To do so, select Run Manager on Model Explorer on the main menu or simply click the. If there was a problem in running the simulation, a Status Report will appear describing what errors occurred.
Upon successfully completing a run, there are numerous ways in which to view the results of the simulation.
We will illustrate just a few here:. To view the report, select Report Status or click the. For the system tutorlal just analyzed the report indicates the quality of the simulation is quite good, with negligible mass balance continuity errors for both runoff and routing Also, of the 3 inches of rain that fell on the study area, 1.
The Summary Report contains tables listing summary results for each subcatchment, node and link in the drainage system. Total rainfall, total runoff, and peak runoff for each subcatchment, peak depth and and hours flooded for each node, and peak flow, velocity, and depth for each conduit are just some of the outcomes included in the summary report.
To view the Summary Report select Report Summary from the main menu or click the. For our example, the Node Flooding Summary table indicates there was internal flooding in the system at node J2. Normally such water will be lost from the system. The option also exists to have this water pond atop the node and be re-introduced into the drainage system when capacity exists to do so. The Conduit Surcharge Summary table shows that Conduit C2just downstream of node J2was at full capacity and therefore appears to be slightly undersized.
Simulation results as well as some design parameters, such as subcatchment area, node invert elevation, link maximum depth can be viewed in color-coded fashion on the study area map. To view a particular variable in this fashion:.
For our example, this dialog can be used to graph the flows in conduits C1 and C2 as follows:.
InfoSWMM SA for the EPA SWMM5 Tutorial
SWMM can generate profile plots showing how water surface depth varies across a path of connected nodes and links. As you move through time using the Map Browser or with the Animator control, infpworks water depth profile on the plot will be updated.
Observe how node J2 becomes flooded between hours 2 and 3 tutodial the storm tutorixl. The appearance of a profile plot can be customized or it can be copied or printed using the same tutoorial as for a time series plot. In the analysis just run we chose to use the Kinematic Wave method of routing flows through our drainage system. This is an efficient but simplified approach that cannot deal with such phenomena as backwater effects, pressurized flow, flow reversal, and non-dendritic layouts.
This procedure, however, requires more computation time, due to the need for smaller time steps to maintain numerical stability. Most of the effects mentioned above would not apply to our example. However we had one conduit, C2that flowed full and caused its upstream junction to flood.
