What is the difference between Median Inlets versus Grate Inlets?When should each be used??
Grate Inlets are set with one side against a curb. Therefore, they receive side flow along only one side of the grate (the length side), and the frontal flow is calculated using a typical curb and gutter section.
Median Drop inlets are set in the bottom of a ditch (Shallow Swale section on the Gutter Tab). They receive side flow from two sided, and the frontal flow is calculated as a portion of the ditch flow.
