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

Turbulence in simulation result

Hi, everyone, 

I use dynamic wave to simulate a piece of pipe network, and I set up the outfall boundary to time series which I measured several months ago.  The outfall  boundary is surcharged when it rains. But after the simulation, I find the total

Problems with SSA version of SWMM computing peak inlet flows

I am using Autodesk SSA version of SWMM.  I am getting unreasonable results that are too high when the inlet is completely submerged by a flow that is say 5 times the inlet capacity.  The program appears to calculate the flow in the upstream link bas

Piezometric Head of the Nodes in SWMM 5.

How do I get the piezometric head ( pressure + elevation head) of the nodes in the result of SWMM 5? Is there options for this or something has to be implemented in the source code of SWMM5 ?  Please throw some light in this regard.

Flow on LID outputs?

Hello,

This might be a simple question for some of you but I am still learning the software....

I am trying to model flow on an LID surface and wanted to ask about the outputs I can get from the software and how I can get it. Is it possible to get the

Channel Parameters Sensitivity

I have develop a event based model to analyze the sensitivity of the channel parameters (Bed and Bank Roughness coefficient, Bed width, Maximum Depth) and the sensitivity of the intermittent storage areas. According to the results, sensitivity values

How is mass balance calculate in the SWMM when there is system loss (internal outflow)

 I used simple schematic to check the mass balance of the model.  When I change the channel bed width, outflow hydro-graph peak was reduced but no time lag of the peak. I have found there is a system loss by internal outflow and due to that, I couldn

ponded area in autodesk storm and sanitary system 2012

Dear all,

Have any one worked with autodesk storm and sanitary system 2012?

I have a question about ponded area in that.

Does ponded area have a significant effect on calculation process?

How can I estimate ponded area accurately?

What will happen if the

pump behavior

Hi

I've set up a pretty straight forward model that involves a storage node with a pump deilvering to a force main which discharges to a gravity main. Gravity main has an orifice at the end to deliver about 60l/s. Pump cut in at 2.1 depth cutout at 1.
