Importing wqpsl

Hi I was importing existing wqpsl.inp (mass loading point sources). However, when i save it back, the values in wqpsl are changing. Any reason,

Thank you for your question. We will have a look at it and get back to you.

Based on the model you provided we determined that the issue was that the input files had specified a time series for open boundaries but none were used. EE assumed that if the WQ time series were specified on C30 of WQ3DWC.INP, then at least one of the number of open BC’s on Card 31 would be non-zero. If the user manually zeroes the series EE and EFDC+ can load/save/run the model. We have fixed EE so this condition no longer occurs and made a new setup package today.

To give more background as to how EE handles point source mass loading and concentration loadings, please refer to this information:• IWQPSL = 1: Mass Loading Option (original /nonEE models)o EFDC (legacy) stores the point source mass loading in the WQPSL.INP file. These BC’s are completely independent of the NQSIJ cells.o If open boundaries are being used, the maximum number of concentration series (per constituent (EE forces them to all be equal)) is stored in C30o When EE loads the WQPSL.INP file, it attempts to match the WQ mass loading BC’s to the EFDC NQSIJ cells. If a match is found, then EE will compute the WQ concentrations from the paired mass loading and flows. o When the legacy project is saved, these new concentration series are stored in WQPSLC.INP and the number of concentration series are stored in the EFDC.EE file.o The total number of WQ series shown in EE will be the number of concentration series from the open BC’s plus the number of generated point source concentration series. o The number of point source concentration series may or may not be equal to the number of mass loading series in the legacy file. That is because EE will try to reduce the number of concentration series if duplicate concentration series are found. • IWQPSL = 1: Mass Loading Option (EE models)o The number of WQ concentration series is loaded from the EFDC.EE file o Then the concentration series are loaded from the WQPSLC.INP file (the WQPSL.INP mass loading file is not used by EE)o If the WQPSLC.INP file is missing, EE will regenerate it from the WQPSL and QSER data, same as legacy applicationso When EE writes the EFDC project, EE will generate a new WQPSL.INP file for use by EFDC and updates the NPSTMSR variable in WQ3DWC.INP.o If the model uses open BC’s, the maximum number of concentration series are stored in C30 (EFDC always uses concentrations for open BC’s).o The total number of WQ series shown in EE will be the number of concentration series from the open BC’s plus the number of point source series.• IWQPSL = 2: Concentration/QSER Option (EE models)o All boundary conditions are defined using concentrations and flowso All concentrations series are stored in the CWQSRxx.INP files for both open and point sourceso The number of series is stored in the WQ3DWC.INP file at card C30o The WQPSL.INP and WQPSLC.INP are not used by either EE or EFDC.
