Table 2-2. Detailed Organization of SWMM Interface FileNote: See Subroutine INFACE for example of reading and writing this file.Variable NameDescription aFROMFIRSTCOMPUTATIONALBLOCKTITLE(1) First line of title from first block, maximum of 80characters.TITLE(2) Second line of title from first block, maximum of 80characters.FROMCURRENTINTERFACINGBLOCKIDATEZTZEROTITLE(3)TITLE(4)Starting date; 5-digit number, 2-digit year plus Juliandate within year, e.g. February 20, 1987 is 87051.Starting time of day in seconds, e.g., 5:30 p.m. is63000. This date and time should also be the firsttime step values found on the interface file.First line of title from immediately prior block,maximum of 80 characters.Second line of title from immediately prior block,maximum of 80 characters.SOURCE Name of immediately prior block, maximum of 20characters.LOCATSNPOLLTRIBA(NLOC(K), K=1, LOCATS)or(KLOC(K), K=1, LOCATS)(PNAME(J),J=1,NPOLL)(PUNIT(J),J=1,NPOLL)Number of locations (inlets, manholes, outfalls, etc.)on interface file.Number of pollutants on interface file.Tributary or service area, acres.Location numbers for which flow/pollutant data arefound on interface file. These may be either numbers(JCE=0) b , or alphanumeric names (JCE=1). NLOCarray if numbers. KLOC if alphanumeric names areaused.NPOLL pollutant names, maximum of 8 charactersfor each.NPOLL pollutant units, e.g. mg/l, MPN/l, JTU,umho, etc., max. of 8 characters for each.26

ContinuedFROMCURRENTINTERFACINGBLOCK(continued)Variable Name(NDIM(J),J=1,NPOLL)QCONVDescription aParameter to indicate type of pollutant concentrationunits.=0, mg/l=1, Aother quantity@ per liter,e.g. for bacteria, units could be MPN/l.=2, other concentration units, e.g., JTU, umho,EC,pH.Con<strong>version</strong> factor to obtain units of flow of cfs,(multiply values on interface file by QCONV to getcfs). All blocks assume inflow is in cfs and convertto m 3 /sec if METRIC = 1.FLOW ANDPOLLUTANT DATAFOR EACHLOCATION.REPEAT FOR EACHTIME STEP.JULDAYTIMDAYStarting date; 5-digit number, 2-digit year plus Juliandate within year, e.g. February 20, 1987 is 87051.Time of day in seconds at the beginning of the timestep, e.g.,12:45 p.m. is 45900.DELTA Step size in seconds for the next time step c .(Q(K),(POLL(J,K),J=1,NPOLL),K=1,LOCATS)Flow and pollutant loads for LOCATS locations atthis time step. Q(K) must be the instantaneous flow atthis time (i.e.,at end of time step) in units ofvolume/time. POLL(J,K) is the flow rate times theconcentration (instantaneous value at end of timestep) for Jth pollutant at Kth location, e.g.,units ofcfs . mg/1 or m 3 /sec . JTU d .a Unformatted file. Use an integer or real value as indicated by the variable names. Integer variables begin withletters I through N.b Parameter JCE indicates whether $ANUM has been invoked to use alphanumeric conduit and junction namesand is included in COMMON/TAPES in each block.c I.e., the next date/time encountered should be the current date/time plus DELTA.d If units other than cfs are used for flow, this will be accounted for by multiplication by parameter QCONV.27
