Would anyone have any idea why my model shows an event mean storage of 20396 cf when I dont have any storage nodes? How is the model storing that amount of water? I'm thinking this is why my total inflow doesnt match my total outflows?
SWMM computes storage in all of the links and nodes, not just storage nodes.
SSA says it uses the SWMM engine, but they don't say what version, or what modifications, if any, they have done to it.
Sounds like your model might not be completely draining during the event duration.
EPA SWMM hydraulic calculation engine for SSA 2013 should be 5.0.21 or 22.
Just curious, how can you not be sure of the version in 2013 now? It says here you're an employee, is that right?
Yes, I am an employee.
The difference between the EPA SWMM 21 & 22 engines are a couple of "engine update" changes that I am not 100% certain are covered.
Sorry, but I don't understand your logic there... it should be just clear...What SWMM version?
It should also be listed in the About under the software Help, like most software list their versions and updates. then in your methodology section, talk about any differences between the SSA engine and the SWMM engine, any modifications.
Example: "We are using SWMM version 5.0.022, however we are not using the LID capabilties", etc...
