1 xpwspg 2010 Modeling The xpwspg capability in XP s products includes building/enhancing WSPG models with GIS/CAD data and presenting models with various graphical outputs. In this tutorial, users will learn how to utilize XP s tools to build a WSPG model (links/nodes) while taking advantage of the full GIS/CAD graphical interface to extract data from GIS files and present results with GIS/CAD data. This tutorial uses the xpwspg Hydraulics mode in xpswmm or xpstorm. The software must be configured to use the WSPG Hydraulics Mode. Users are advised to review the XP User Interface tutorial for an overview of the windows, menus, tools and basic concepts of building and navigating a drainage network with the graphical interface. Level: Objectives: Time: Data files: Intermediate Introduce the steps required to: Layout links and nodes in xpwspg Hydraulics mode using background maps Derive ground elevations and inverts from a DTM Calculate element lengths from the model coordinate system Enter remaining required data for elements in dialogs Run xpwspg Add a network branch to the model, use new JOIN element Run branched xpwspg Obtain results from the output file, Plan View plot, Profile Plot tools. 1 hour \Tutorial\LA\WSPG\rio_hondo.xpt \Tutorial\LA\WSPG\rio_hondo_la_aerial1_UTM_ft.jpg,.jpw (image files) \Tutorial\LA\WSPG\rio_hondo_la_aerial2_UTM_ft.jpg,.jpw (image files) \Tutorial\LA\WSPG\riohondo_UTM_ft.jpg,.jpw (image files) \Tutorial\LA\WSPG\riohondo_UTM_ft.asc (elevation grid file) \Tutorial\LA\WSPG\wspg_encoding_ctm.gen (display settings) \Tutorial\LA\WSPG\profileplot-wspg-ctm.def (plot settings) Part 1 Start New Model and read in a Background Image 1. Open xpswmm / xpstorm / xpwspg Choose Create from Template in the Welcome/License dialog. 3. Enter rio_hondo_xpwspg.xp as the filename for the new data file and click Save. 4. Find and open rio_hondo.xpt (from the Tutorial folder in your local xpswmm / xpstorm folder). This has some display properties set that will make building the WSPG model easier. 5. Ensure that the active mode is Hydraulics by clicking on the icon in the top tool strip. Tutorial 3 XPWSPG Modeling using GIS xpsoftware Version 2010

2 Tutorial 3 XPWSPG Modeling using GIS 6. Ensure that WSPG Hydraulics is the active model by clicking Tools -> Application Settings Choose CONFIG in the drop down box and scroll down to make sure WSPG Hydraulics is checked. Click OK. 7. In the Layer Control window, right-click on Background Images, choose Add Background Image. 8. Choose the Filename browse button and open the file named riohondo_utm_ft.jpg Note that the Destination Rectangle coordinates are filled in once you have selected the file for import these coordinates were read automatically from the accompanying JPEG world file. 9. Click OK to import the file. You should see the aerial photo on the screen and note that there is a new layer under Background Images in the Layer Control. 10. You may want to Zoom & Pan to investigate the Rio Hondo flood control channel. Part 2 Read in a DTM and set Display 1. In the Layer Control window, right-click on DTM, choose DTM Builder. 2. Click the Read ESRI Grid File button, choose riohondo_utm_ft.asc and click Open. After a moment, the listing of data points will appear in the DTM Builder. 3. Click Create DTM, assign riohondodtm as the filename when prompted and click Save (this will save the finished DTM to the hard drive). 4. When the color-filled DTM appears on screen, go to the Layer Control and right-click on the TIN under Surfaces and choose Properties. 5. Click the Display Properties tab, turn ON the Show Major Contour checkbox and enter Click the Color button, slide the Transparency slider to about 30%, click OK. 7. Click OK in the DTM Properties dialog. Note the updated display. 8. After inspecting the updated display, turn off the DTM display to make it easier to see the background image that will serve as reference while building the hydraulic network in the next steps. Turn OFF the DTM checkbox in the Layer Control. Part 3 Create Hydraulic Network and Calculate GIS Data 1. Select the Link Tool from the right-side tool bar. 2. Starting at the outlet works of the detention basin (the upstream end of the channel) shown in the upper right of the aerial photo, digitize links and nodes by clicking at each node location shown in the following figures. Note that a curved link can be made by clicking intermediate points while holding the CTRL Key (if desired). 3. Note that you should click along the left side of the channel at critical points where junctions or bridge exist and where the channel transitions start and end. Page 3-2
