Let’s get a basic idea of what inlet control is from a culvert hydraulics standpoint and compare it to outlet control. When you have a flow through a culvert, there is a limit on the capacity of fluid conveyed through the culvert. Inlet control applies when the culvert barrel has more capacity than the inlet will accept. Outlet control is the
“One’s company, two’s a crowd, and three’s a party” may not exactly apply to manufactured treatment devices (MTDs), but hopefully, this post can offer some insight that will make designing multiple MTDs in parallel a little more fun.It is common practice to utilize different Best Management Practices (BMPs) in series or “treatment trains” to
