Dynamic hydrology-hydraulic water quality simulation model
If a model contains more than 508 time series that have external files, the engine will throw "ERROR 361" even these files are all valid. This seems to be a...
If a transect has its right bank not defined, i.e. Xrightbank = 0, the engine still use its roughness in the flow calculation in transect.c getFlow() method: if ( findFlow...
The default value for Initial Deficit is incorrectly entered by the interface for the G&A and modified G&A methods. 
In the GUI, the void ratio entry does not accept values grater than 1. However, if void ratio= voids/solids, it can be greater than one.
With the addition of the 6th Parameter in the INP for Subcatchment parameter in 5.1.015, the Project > Detail should show a Param6 in the header for [INFILTRATION] 
The Maximum Infiltration Volume feature works fine with the original Horton infiltration model (it correctly shuts off infiltration at 1-5 inches for the various subcatchments in the attached file). But...
In dynamic wave routing, the conduit loss calculation seems to have some issues. The loss should apply the flow-to node, not the flow-from node. Otherwise, the routing continuity error will...
Would there be any interest in using the NetCDF as the output file format for SWMM? It is self documenting, portable, and is able to scale well.
In control.c executeActionList() method, the following code if ( RptFlags.controls ) is changed to if ( RptFlags.controls && a1->curve < 0 //(5.1.011) && a1->tseries < 0 && a1->attribute != r_PID...
Please update affiliation in the Readme file, Introduction, and elsewhere for the Master link as well: Also indicate that the master and develop are from SWMM 5.1.014. “This is the...
