Adverse Slope Convention in SWMM 5

Subject:  Adverse Slope Convention  in  SWMM 5

 If the slope of a link  is negative and the solution  is dynamic wave then the following data will be switched in link.c in SWMM 5.  All upstream data for the  link  is switched to the downstream end of the link  and  vice versa.   The means that if the flow  is from the original upstream node to the downstream node the flow  will  be negative in the output of  SWMM 5. 

 Negative flow in SWMM 5 means:

 1.   The link has an adverse or negative slope,

2.   The link  has reverse flow if the link slope is positive.
