New SWMM 5.1.006 is now available from the EPA Site

http://www.epa.gov/nrmrl/wswrd/wq/models/swmm/

with these engine changes

-------------------------
Build 5.1.006 (5/19/2014)
-------------------------

Engine Updates:

1.   The updating of the next time that detailed LID results
     should be written to file during a simulation was modified 
     to avoid an off-by-one error.

2.   The number of decimal places for hourly evaporation written
     to a detailed LID report was increased.
     
3.   The amount of soil water available for evaporation in
     LID units with soil layers wasn't being limited by the
     water remaining below the wilting point.

4.   The equation that computes the rate of water infiltrating
     into permeable pavement LIDs had a misplaced parenthesis.

5.   There was a units conversion error in computing the
     contribution of a pollutant in direct precipitation
     to the water quality on a subcatchment.
