  1. Trim Surface

    is used to define the boundary of the surface loaded in the  Surface Data form to remove information that is not necessary by the design. I.e. if a large LIDAR tile has been simply loaded and it only requires a certain part of it. xpdrainage 2017.3_trim_surface.png Draw a polygon The Drawing Mode tool XPD201
  2. Print

  3. Pollution Concentration

    Pollutant Concentration is added on the Pollution tab of an Inflow. Runoff from each area can contain a concentration for each pollutant specified for the area type. Concentration is measured in mg/L, and does not vary in time in the inflow area. The default set of pollutants can be entered through the Pollutant
  4. Analysis Ribbon

    The Analysis Ribbon allows the analysis criteria to be specified and an analysis performed. xpdrainage2018.1_analysis_ribbon.png The different options are discussed within the sections listed below, please select one of these options for details.

  5. Analysis of Connections

    The following Connection Types are available in xpdrainage, each type is processed differently during the Analysis. Pipes and Channels When a pipe or channel is analysed its capacity is taken into account based on either the Manning Formula or Colebrook-White Formula using the bottom slope and the full section. Wat
  6. Hard Copy Headings

    The Hard Copy Headings dialog box provides users the option to specify the headings to be displayed at the top of each page when printing the model. xpdrainage2017.3_hard_copy_settings.png XPD2015.v3-Ribbon-Menu-File_Menu-Hard_Copy_Headings1.png The following elements can be customized in this dialog: Page Hea
  7. First Order Decay

    First order decay is a more complex method for analysing pollutant removal based on Exponential Decay. The method needs to act on the body of water in each stormwater control, rather than on the output. This method determines the percentage of pollutants removed depending on the amount of time taken for water to pass t
  8. Synchronise Manhole Invert Levels

    When working with large sites, it can often be tedious to make numerous minor checks and adjustments. The Synchronise Manholes option allows you to adjust the invert levels of the selected manholes to match that of their lowest connection (incoming or outgoing). The manhole cover levels will not be changed, and the dep
  9. Desbordes Rainfall

    The Desbordes Rainfall refers to the double-triangle hyetograph that was proposed by Prof. Michel Desbordes (Université de Montpellier, France) in the late 1970s. One key principle behind the approach is that the rainfall hyetograph is not trying to replicate observed rainfall patterns, instead its characteristics are
  10. Transmit Design

    The Transmit Design command provides users the option to package their designs, making it easier to share with clients and collaborators.  xpdrainage2017.3_transmit_design.png xpdrainage saves the packaged design into the same folder as the open .xpdx file by default. To save the package into a different folder,
