Hi There
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

In swmm 5.1.007, they are the same. which is right?
Read more…You can model water quality as a SWMM 5 inflow time series using the following steps:
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

I am very new to the SWMM5 and working on a project in which i have to develop unit hydrograph and pollutograph in SWMM. please help me out.explain me a detailed procedure to develop hydrograph and pollutograph. Actually I
I lumped my catchment - disregarding the details of the sewer nework and repalacing it with an equivalent subcatchment - but it offten reacts faster than the detailed sewer network model. Any research or idea on this? I tried to include a link down
