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. Additionally, these SWMM5 layers can be exported to the LandXML format, however due to limitations of the LandXML format, and Civil 3D's support of it, only a few attributes are supported at this time.Continuity error related to pumping and inclusion of on-site pumping measurements to simulations PCSWMM now supports importing subcatchments, conduits and junctions from a single LandXML file as another way of importing data from Civil 3D. More functions will be added in the upcoming releases - let us know what functionality you would like in the feature requests forum. Various commands can be stored and executed in series, and PCSWMM Real Time can execute scripts both before and after real-time SWMM5 runs. Initial support for scripting in PCSWMM has been released. IDF curves can also be compared to observed rainfall events. IDF curves can be imported from NOAA precipitation frequency estimate files, Environment Canada and MTO IDF data, as well as manually entered or computed from rainfall time series. This new feature allows you to import, create and manage IDF curves for use by the Chicago and Symmetric design storms, as well as the new Modified Rational runoff method. A single model can use any combination of these runoff methods for its subcatchments, and subcatchments can be easily converted from one method to another. PCSWMM now has the ability to compute subcatchment runoff using a number of alternatives to the SWMM5 non-linear reservoir routing method, including Modified Rational, SCS triangular UH, SCS dimensionless UH, Delmarva UH, Snyder UH, Nash IUH, and Clark UH.
