If STRUCIDS has been populated with a list of STRUCNAMES corresponding with the conduits read from the SWMM Result file, this routine will compile summary statistics for each conduit into the table _CSOStats. It is useful for compiling long-term CSO statistics. 

 

STRUCIDS

NPDES	STRUCNAME	FULLNAME	RECSTREAM	RAIN GAUGE ID	Acres	UsePositiveFlow
CSO 002	PMH28W				0	Yes
CSO 004	PMH456W				0	Yes

 

_CSOStats

Outfall	VolMG	Hours	Events
CSO 002	0.24	2	1
CSO 004	0.39	50	6

 

The procedure is as follows:

1.  _OutfallHydrographs is populated with totaled flow at each timestep for each NPDES ID according to the query Append_OutfallHydrographs

2.  _OutfallHydrographs is updated with event numbers based on the user-specified interevent time for each NPDES location using a looped procedure.

3. Event totals for each NPDES ID are compiled into _ModelOutfallStatsByFlow using a query in the program code.

4. Summary statistics for the period of interest are compiled into _CSOStats using a query in the program code.
