This is the data input file for a CDM/CDMSmith Pittsburgh versionSWMM4 model from 2000 to 2004. It has additional capabilities beyond SWMM 4.4 and was made as a bridge between SWMM 4 and SWMM 5, thus the 4.5 number.

* <<<<<<<<< SWMM 4.45A(beta) RUNOFF DATA FILE >>>>>>>>>
*
*
* This is an input data file to the SWMM 4.4 Runoff Block for
* modeling watershed quantity and quality. All lines with an
* asterisk in column 1 are comment lines and are ignored
* by the program.
*
* Input data are free format and may be up to 230 columns wide.
* You must have a value for every data column even if the program
* will not actually use a given value. A slash (/) may be used
* to indicate that remaining fields should be filled with "no data
* entry" or null-entry. This almost always means those input
* parameters will be zero. (See example for data group L1.) A very
* common data input error is to accidentally omit required parameters
* at the end of a data group. There must be at least one space
* (or comma) between every input value.
*
* Caution! Data lines that are "wrapped around" (continued on
* two or more lines) should have a blank in column 1, unless a
* card identifier is needed.
*
* Alphanumeric data ($ANUM option) should be enclosed in single
* quotes. These include all references to subcatchment and
* channel/pipe/inlet names.
*
* In general, SWMM parameters with names that begin with the letters
* I,J,K,L,M,N are integers (e.g., NSCRAT() ), following the usual
* Fortran convention, and entered values must not include a
* decimal point.
*
* To avoid literary quotes being printed in output, use $NOQUOTE
* after MM line.
*
* SWMM uses both U.S. customary units and metric units. The
* examples use feet, cfs, acres, inches, inches/hour, and miles/hr.
* If metric is specified substitute meters, cms, hectares,
* millimeters, millimeters/hour, and km/hr.
*============================================================================
* The SW card sets up the interface files to be used or created.
* There is one output file (#9) that will contain the time series
* of flows and pollutant loads for subsequent blocks.

* $ANUM ==> Use alphanumeric labels for subcatchment and channel/pipe

* The B3 line contains time step and duration-of-run parameters.
* The program starts at date/time indicated on line B1. It then
* uses time steps WET, WETDRY and DRY to simulate to an ending date/time
* specified by parameter LONG.
*
* B3 Line :
* WET : Wet time step (seconds). WET must be => 1 second.
* Typical: 60-300-900 sec for event simulation; 900
* or 3600 sec for continuous simulation. WET time
* step is used only during time steps with precip.
* WETDRY : Transition (no rain but water on surface or in
* channels) between wet and dry time step (seconds).
* WETDRY is used during 1) residual overland flow
* (no precipitation), 2) residual channel/pipe flow,
* 3) snowmelt, 4) groundwater outflow to channel/
* pipes. WETDRY should be greater than or equal
* to WET and less than or equal to DRY.
* Typical: = WET for event simulation; 3600 - 7200
* for continuous simulation.
* Note, decrease WETDRY toward WET for better
* resolution and lower continuity errors, but at
* the expense of greater computer time during
* continuous simulation.
* DRY : Dry time step (seconds). DRY must be greater
* than or equal to WET. Typical: = WET for event
* simulation; 7200 - 86400 sec for continuous
* simulation. DRY time step principally affects
* groundwater ET and deep percolation and residual
* surface evaporation and infiltration.
*
* Note: DRY and WETDRY time steps are only approximated during
* time intervals with no precipitation. Thus, print-outs may
* occur at intervals that do not correspond exactly to DRY
* or WETDRY.
*
* LUNIT : Units of LONG (simulation length).

* will be multiplied by this value.
* TIPM : Weight used to compute antecedent temperature index,

* more weight to past temperatures. Values > 0.5
* essentially give weight to temperatures only
* during the past day.
* RNM : Ratio of negative melt coefficient to melt

* Camp, Dresser and McKee, Inc., Annandale, VA
*
* These lines, plus H5 lines, define triangular unit hydrographs (UH)
* to compute subcatchment I/I response from rainfall record on NSCRAT(1).
* The response is computed before the time step simulation and stored on
* NSCRAT(8) (required if this I/I procedure is used).
* An initial abstraction of up to DSTORE in [mm] is subtracted from
* rainfall before computing rainfall excess at each time step. The
* initial abstraction is regenerated during dry weather at a rate of
* DREC in/day [mm/day].
* Up to five sets of three triangular UHs may be input in the F4 lines.
* Any subcatchment may use a fraction (defined on H5 lines) of flow
* produced from each of three UHs selected from any of the up to
* five sets input on the F4 lines.
*
* The triangles are defined by TP = time to peak and K = ratio of recession
* limb to TP, so that the time base = TP*(1+K). Peak flow, Qp, is then
* calculated in the program so that the volume (area) of the triangle =
* 1 cfs/ac-in or 1 cms/ha-mm.
*
* Three triangles may be used (all starting at the same time) so that
* one may define a fast response, one a delayed response, and one a
* lengthy response, if desired.
*
* The time step TSTEP (UH duration) must equal the rainfall time
* step (THISTO). Rainfall can be input on the E-lines as usual, or
* rainfall already stored on NSCRAT(1) may be used, i.e., from prior
* Runoff or Rain Block runs.
* Time step TSTEP2 is the time step used for computation of the UH
* response and should be an integer fraction of (or equal to) TSTEP.
* TSTEP2 = WET time step in the Runoff Block is a good idea.
* There is a limit of 300 UH points for a given rainfall increment. An
* error message is printed if this is exceeded, which can be caused by
* too long a time base and too short a value of TSTEP2.
* The RDII routine is designed to be compatible with the variable time
* step used in the Runoff Block. Values of I/I are linearly interpolated
* from the file on NSCRAT(8) at each time during the simulation.
*
* H5 lines may be entered only for desired subcatchments.
* If quality is simulated, constant concentrations for I/I are entered
* on data line J6.
