Hi there users,Having some trouble modelling rain-gardens in SWMM. I have a few rain-gardens draining impervious surfaces in an urban catchment. In checking the detailed rain-garden flux files, it would appear that there is no exfiltration and the s…

"Thanks a lot Robert.
Hey - I've got another query if you don't mind. 

I've just stumbled across a strange SWMM error - for all my links, I cannot seem to view any output. I get an error "no objects to display" even though I know there is data there…"

"Hi there Robert,

Thanks very much for your quick reply. OK - just another query on this. Back to my example. Let's say my 100 m2 sub-catchment (before LID) is 100% impervious. I deploy the 10 m2 LID. I select that 50% of the impervious area drains…"

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…
