Transects in InfoSWMM and SWMM5

Transects in #InfoSWMM and #SWMM5
  • There is only one transect per link and the shape stays the same from the  upstream to the downstream node
  • The links are irregular channels with the name of the imported HEC-RAS transect defining the shape of the transect (Bullet 1)
  • The transects are converted from the station/elevation pairs to normalized depth and width tables (Bullet 2)
  • The inverts used for the links are independent of the station/elevation pairs, if the offset is zero then the  invert of the link equals the invert of the upstream or downstream node (Bullet 3)
  • The normalized tables are shown in the text report file (Bullet 4)
  • If the node depth or rim elevation is lower than the depth of the transect the depth is increased internally in the engine (Bullet 5)
  • If you only have one transect for the culvert you can assign the same transect name to both the upstream and downstream irregular links

Hidden features of the 1D St Venant solution for SWMM5, InfoSWMM, and ICM SWMM Networks

1/ There is also an ArcEngine version of InfoSWMM call InfoSWMM SA. I will SA to show some hidden features of the 1D St Venant solution f...
