Overview
Culverts are generally used to move water from one side of a road to the other. They are often used as alternatives to bridges. The wingwalls of culverts can have an effect on culvert capacity due to entrance losses. The angle that wingwalls can be built for culverts can range from 8 degrees to 30 degrees or more. After reviewing this 5 hour course, the student will have valuable information that can be used to analyze the effects of inlet geometry on hydraulic performance of box culverts.
The course materials are based solely on the materials “Effects of Inlet Geometry on Hydraulic Performance of Box Culverts” as published by the Federal Highway Administration. This material should be studied by those working in hydraulics, structures, transportation engineering or anyone that wishes to learn more information regarding the effects of inlet geometry on hydraulic performance of box culverts.
The student must take a multiple-choice quiz consisting of twenty-five (25) questions at the end of this course to earn PDH credits.
