The NetSTORM module lets the user apply the STORM methodology to a series of linked control structures, such as CSO regulators in series or interconnected pump stations.

 

 

 

The precipitation file should be in either of the two formats used elsewhere in NetSTORM, i.e.

MM/DD/YYYY HH:MM Value [Gage]

or

Gage YYYY MM DD HH MN Value

 

or it can be a special multi-gage format:

NumGages YYYY MM DD HH MN Value1 Value2 ... ValueN

 

External Hydrograph

A hydrograph is read (space delimited, free format) which has date and flow information as shown:

 

YYYY MM DD HH Q1 Q2... Qn

 

where each Q is a flowrate in million gallons per hour.  The hydrograph # corresponds with the column from which Q is to be read for the current structure (between 1 and 5), and the scaling factor is a value by which the source hydrograph is to be scaled.  In this manner, the same hydrograph shape can be used by multiple structures.  The program is dimensioned to read up to 50 hydrographs.

 

Here's a sample two hydrograph input: 

 

1993 1 1 0 1  1 

1993 6 1 0 2  0 

1994 1 1 0 3  0 

1995 1 1 0 0  2 

 

The program always uses the most recent value, so that the 1/1/93 value of 1 MG/h for hydrograph 1 is used until 6/1/93 when it's reset to 2 MG/h (and hydrograph 2 is reset to 0).
