Calibration Concepts
From the blog Serendipity as useful discussion on calibration
..ask what is the purpose of a climate model. The second half of the George Box quote is “…but some models are useful”. Climate models are tools that allow scientists to explore their cu

(Response to Kenneth L. Orie's discussion of same title)
================================================
The request for model AND all the details is indeed concerning. I would be very reluctant to release this without accompaning report to cover; as

There is an open records law request for an electronic version of my model that I am using to develop the long term control plan for a community. I provided the base version with model construciton parameters but they are demanding calibration files,

I am trying to determine if I am using the proper CN Values for input parameters in SWMM 5.0. I've used the NRCS runoff curve numbers in the input for each subbasin determined from weighted CN based on landcover. Should the impervious be removed fr

Hi,
Anyone who knows how to use the "item number" in GetSwmmResults function, please be kind enough to elaborate it using the following example.
There are 5 weirs and 2 orifices in the network and one wanted to get the flow only through the orifices.

"GetSwmmResults" function
Hi,
I am bit confused on calling the results of the SWWM using the above function.
Interfacing guide explains it as follows; but I guess I am confusing specially shown at bold-italic letters.
If anyone knows how to call the results using the above func

Modeling of CSO Control Technologies in SWMM
Hello All
I was wondering if any of you have worked on CSO control alternatives as the city i reside is looking for alternatives assessment.
Some of the alternatives we have are :
Satellite Treatment WWTP's (There has to be more than storage settin

Hi,
Anyone knows what is the exact default area of a junction and the possible ways to input an another area for the junstion?
Thanks
Calling some results SWMM results to another program
Hi,
I am trying to call some results of SWMM through another program.
(Example; I wanna call the orifice flows from the attached problem to another program which is in C++)
If anyone knows; the coding to do this please let me know.

Area of a Junction
Hi,
For a junction we specify the geometric data, but the area of a junction is not an input.
Even though we don't specify it the program works. So how can we find the actual area of the junction?
We obviously know the height, but the area???
Thanks

SWMM Data browser
hi!
Data browser is the box left side of the screen in swmm.
I tried to resize vertically the upper box of the data browser and accidently I pressed so it cannot be seen. The splitter bar seems to be active, but cannot be used. I tried to reinstall sw
Modeling subsurface storage
I’m trying to represent a subsurface storage unit that consists of 5, 300-foot long 66” pipes with a 66” pipe distributing flow and another 66” pipe collecting flow at the other end. This layout doesn’t have a standard outlet structurethat is easily

Pollutant to a node
Hi,
Is it possible to add a pollutant concentration (eg. TSS = 20 mg/L) to a node at a network in SWMM?
Thanks a lot
