#SRCT FOR LID CALIBRATION PCSWMM HOW TO#
I have set the units as inches and cumulative precipitation, with my subcatchments imperviousness set to 100%, as well as specifying LID parameters (dedicated entire subcatchment area to area of LID rain barrel height, outlet, etc.)Does anyone have any suggestions as how to go about fixing this issue? Some context: My project invovles rainwater harvesting using the LID capabilities within SWMM. However, the output of my model, using the assoicated precipitation values as input for my time series, indicates that there is only about 20 inches of precipitation. Greetings fellow SWMMers,I am working on my masters project and I am struggling to get the output of my model to match with the precipitation data I have.My precipitation data indicates that I should have about 50 inches of cumulative rainfall for the year 2008. How should I understand that my sensibility analysis results in no response from changing my RTK values?Please note that I am ignoring initial… Read more… Everything works nicely in my calibration for DWF and all the steps work well for the RTK unit hydrograph creation, however, when I use the SRTC tool I see no response in my hydrographs (comparing my simulated and observed hydrographs), implying that my RTK parameters have no effect on my hydrograph response. I have also tried to calibrate the RTK parameters for short, medium and long-term responses. I have followed all the steps to derive an RTK unit hydrograph and I have implemented it in my simulations. Hi everyone,I am currently having problems with calibrating/finding my RTK parameters and derive a unit hydrograph for my wet period simulations, so any help is more than appreciated!! I have set up my DWF and flow patterns, and I have calibrated my model using my field flow measurements and the SRTC tool implemented within PCSWMM. I checked my status report and it seems to me that… Read more…Ĭalibration of RTK parameters using SRTC tool from PCSWMM When I changed this and runt, my model again, the continuity error went from ~ 3% to 7%. Up to hear nothing is out of extraordinary, however, at first, I set the outlet offset of the upstream pipes to the pumping stations to 0 m as no information was known in advance.My new model, same conditions as above, includes the offset of the upstream pipes for each pumping station.
I have likewise set up the calibration for wet conditions and results are fair enough for both cases.
I am working with PCSWMM (I apologize as I am not using SWMM per se) to set up my DWFs and flow patterns, run and calibrate the model (I have 7 points for calibration purposes). The system is roughly composed of 100 km of pipes, 13 lifting pump stations (34 pumps) and 1,600 junctions. Thank you all in advance!I am currently working at simulating the complete sewer system of a municipality. Hi all,I am reaching out hoping someone can enlighten me with two questions. Continuity error related to pumping and inclusion of on-site pumping measurements to simulations
