Introducing model build

Step-by-step:

Once you have your surface data imported and configured to appear as you wish, you can start building your drainage system.

Keep in mind that the goal is to build a computer model representation of what has been built in reality, or what will exist in reality, depending on the type of plan you are working with. You may have to make some assumptions during the model build process, but the goal is to create a model that is as close to reality as possible.

1. In the Toolbox, expand Junctions and review the junction type options:
• manholes
• simple junctions
• standard manholes
  

2. Expand Connections to review the connection options:
• culverts
• pipes
• channels
  

3. Expand Stormwater Controls to review the stormwater objects:
• ponds
• trenches
• tanks
• SuDS structures
  

4. Expand Inflows and review those options:
• Base Flow
• Catchment Area
• Green Roof
• Hydrograph
  

Best practice is to place junctions, then connections, then stormwater objects, then inflows. Connect drainage system objects starting upstream and working your way downstream.
