Continuity error related to pumping and inclusion of on-site pumping measurements to simulations

Hi all,I am reaching out hoping someone can enlighten me with two questions. Thank you all in advance!I am currently working at simulating the complete sewer system of a municipality. The system is roughly composed of 100 km of pipes, 13 lifting pump stations (34 pumps) and 1,600 junctions.  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). I have likewise set up the…

Rain gauge Time-Series

Good day I am using daily rainfall data to model my catchment. For the time series, does rainfall have to be 7 digits. for instance, 0mm of rain inserted as 0000000 and 2,2mm as 000002,2. my supervisor has told me to use this way of inserting data. will it make any difference if i do not use this way of inserting my rainfall data.

LID Control Editor

Hi there, Very new SWMM user here. Interested in defining some LID Controls so I can select them for my subcatchments in the drop down menu in the editor.  It seems I need to first define the Controls and how they are routed using the specialized property editor "LID Control Editor". Does anyone have recommendations for how to add this editor to my SWMM 5.1 interface? Thanks! -Ben

Control Rules

Rule 1IF SIMULATION TIME >= 0THEN ORIFICE UnderdrainPipe SETTING = 0PRIORITY 1Rule 2IF NODE GravelSU DEPTH > 0.6THEN ORIFICE Backtosoil SETTING = 1ELSE ORIFICE Backtosoil SETTING = 0PRIORITY 2My intentions are: Rule 1, The orifice "UnderdrainPipe" starts as closed and is always closed for the entire simulation, and Rule 2 If the depth in GravelSU storage unit node rises to 0.6ft or greater, another Orifice Backtosoil is supposed to open and convey water.SWMM is not responding to my intentions.…

Underground Storage Units

I am currently attempting to model in SWMM Stormtech chambers as a subsurface pond/storage unit connected to a surface pond with a higher stage. How do I cap off the underground system so water will not pond higher than the top of my chambers? When i run the model, it wants to flood and have the water go to a higher elevation.Since the system is capped, once the chambers fill up, water should backflow to the pond.Thanks

SWMM Times-series input options

Very glad that i join the group. am new to SWMM5.1.12 Version.currently am doing modeling the stormwater for a small urban catchment.no difficulties while studying and applying the model but i only have daily recorded rainfall data-set which am confused either SWMM accepts only timeseries values at interval of 5,15,hourly?or is it recommended to use daily intervals for simulation? and what possible uncertainities could happen if its ok to use? please,appreciate any one helping me.tnx

How are the St Venant Units used in #SWMM5?

 Overview In this blog we example the St Venant terms used in SWMM5 as equations, table, graphs and units.  We use a QA/QC version of SWMM 5 that lists many more link, node, system and Subcatchment variables than the default SWMM 5 GUI and engine.  This also applies to #InfoSWMM and any software the uses the #SWMM5 engine. How are the St Venant Terms used in SWMM5? Figure 1 shows the terms and Figure 2  and Figure 3 shows the terms in a SWMM5 table and SWMM5 graph.  dq2 = Time Step * Area…

What Are the Features Ideal Soccer Shoes Should Have?

Players in the game of soccer need to be able to move quickly and effectively in order to get the ball past their opponents. This means paying attention to their equipment, not just what they wear, but also what they use to run with. Shoes are one of the most important pieces of equipment that players should invest in, not just for protection but for agility as well.They Should Be Durable Soccer is a demanding sport in which the player is constantly running, jumping, tackling, and kicking. The importance of finding the right shoe can't be over-emphasized when it comes to your performance on the field. A pair of shoes should be durable because you are often running or kicking with them. The shoes should also have features that promote comfort for long periods of time. They should also have good arch support because this will help prevent injury. If you're looking at buying soccer cleats, make sure they fit properly so that they don't cause pain while playing. You want to find something…

Multiple simulations with SWMM5 in DOS version

Hi everyone, I need to run a large number of simulations (approx. 15000) with different sets of LID design parameters. My objective is to get model responses (e.g. infiltration, surface runoff, etc.) against different sets of LID design parameters. I know the way to run SWMM5 with a batch command, however, Is there any way to run together all simulations iteratively, where each simulation will pick one set of design parameters and produce a report file. Your responses will be highly appreciated. Thank you

I have likewise set up the calibration for wet conditions and results are fair enough for both cases. 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. When I changed this and runt, my model again, the continuity error went from ~ 3% to 7%. I checked my status report and it seems to me that…

Calibration of RTK parameters using SRTC tool from PCSWMM

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 have followed all the steps to derive an RTK unit hydrograph and I have implemented it in my simulations. I have also tried to calibrate the RTK parameters for short, medium and long-term responses. 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. How should I understand that my sensibility analysis results in no response from changing my RTK values?Please note that I am ignoring initial…

Export time series of all nodes in one text file for SWMM

Hi,I am trying to make a link between SWMM and MATLAB (couple operation) to derive optimal policies. So, I call SWMM in MATLAB in each function evaluation process and need its results for decision making of optimization algorithm.The problem is that I need to export data of some control nodes in one "text file" (for example time series of depth in one internal node) to have access to that data and be able to evaluate the objective function and change the policy until convergence. As I see,…

Safe way to change simulation data during runtime

Hello,I'm working on the coupling of  SWMM with a homemade 2D superficial flow model. The later is written in Python.For this purpose, I'm currently writing a Python wrapper for SWMM using ctypes. So far I managed to control a simulation from Python using swmm_step() and get results at each time-step using node_getResults(). But for my purpose I will need to exchange nodes data at runtime. Simply put, at each time-step I need to read values from given nodes, and then update them before the next…
