A storm drain system is only as effective as the inlet grates provided.
A very expensive piping system can be rendered very ineffective if the number and capacity of inlets is compromised.
While inlets are often placed at intersections as a matter of course, inlets between intersections are often ignored.
Inlets provide the means for the runoff from the surface to reach the piping system. This series of courses provides a discussion of the various types of inlets, computations necessary to determine the interception capacity of the inlets, and a discussion on inlet location and spacing.
This 1-hour online course (Part 2 of a series) provides a discussion of computations necessary to determine the capacity of various curb-opening inlets, slotted inlets and combinations of grates and curb-openings. Part 1 provides a general discussion on types of grates and provides computations for inlet grates. A third course (Part 3) discusses inlets in sag locations. A fourth course (Part 4) covers inlet locations and spacing. Another course deals with flow in gutters, which is directly related to inlet capacity.
The student should have an understanding of flow in gutters before taking this course. The text of the course is taken from the Federal Highway Administration's circular on Urban Drainage. It is not necessary to take Parts 3 and 4 of this course, but it is strongly recommended that the student take Parts 1 and 2 prior to taking this course and it is also necessary to either take the course on 'Gutter Flow' or have a good understanding of the computations involved in gutter flow.
There will be a multiple-choice quiz at the end of this course.
