Hi every one,
Can any one help me with compiling SWMM5 code?
I tried to compile different versions of the code in Visual C++ express and I am not sure which version I should compile. For example when I build " swmm51010" or some lower versions I get

I don't know if I've missed something, but I've been trying to plot two time series in a single plot (precipitation and runoff) in EPA SWMM5, but I cannot find how I can reverse one y-axis (for the precipitation) so that I have bars pointing d

In the Summary Report (of SWMM 5.1.010), the *.rpt file, under the "Node Depth Summary" table there's a column with a heading that reads "Reported Max Depth". Each (depth) value listed under this column is always less than the "Maximum

I'm working on a swmm interface and I'm trying to retrieve volume data at nodes from the shared library.
However, it seems that Node[j].fullVolume and any other node volume information is always zero (should be different for storage, though):

I have a rainfall file that had been modified by the City (attached).
For each row, there is 24 numbers for each hour of that day.
It is so big containing every hourly record for 30 years.

I am a new user of SWMM5 and I am working on a model to know the flood depths at nodes. I noticed that in kinematic wave, there are no results for max ponding depth, but instead shows max ponding volume. Please advise on how I can determine

1. Model Water Quality (TSS for Example)
2. Add the needed inflow Time Series at a Node
3. Include both a Flow
4. and a TSS Time Series
5. The TSS time Series is

Just a query regarding LID's in SWMM. Let's say that impervious sub-catchmant A has a total area of 100 m2.
Let's say that I deploy a LID into sub-catchment A (a rain barrel) and set its surface area as 10 m2 (thus it occupies 10% of sub
