Culvert Design
... on certain design conditions, we will design a couple of culverts. We will design a circular concrete pipe culvert and a concrete box culvert. We will use nomographs for the design. We will also design rip rap for erosion control. The student must take a multiple choice quiz consisting of ten questions at the end of the course to earn PDH credits. State Board Acceptance This course can

Bottomless Culvert Scour Study
...Culverts are generally used to move water from one side of a road to the other. They are often used as alternatives to bridges. Culverts can be four sided or three sided, depending on the application cost and other design factors. The three sided culverts are bottomless and are useful to decrease the amount of environmental impacts along its length. This course will address several design

Effects of Inlet Geometry on Hydraulic Performance of Box Culverts
...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

Design of Conduits Culverts and Pipes
...culverts, and pipes vary due to life cycle considerations, material types used, loading types applied, and construction methods utilized. This course provides guidance on applying different types of loading such as (a) internal/external pressure, (b) vertical and horizontal pressures due to groundwater, surcharge water, and concentrated live loads, (c) trench earth loading with or without

Hydraulic Design of Energy Dissipators for Culverts and Channels
...culverts can cause erosion and subsequent sedimentation problems if not controlled at the source. To mitigate this problem the discharge energy can be dissipated at the source. This course will provide design information for energy dissipation problems at culverts.
Several energy dissipators will be discussed including USBR Type III and IV stilling basins, SAF Stilling Basins, CSU Rigid

Design of Roadside Channels with Flexible Linings Part 2
...nd backslope and convey that runoff to larger channels or culverts within the drainage system. This initial concentration of runoff may create hydraulic conditions that are erosive to the soil that forms the channel boundary. To perform reliably, the roadside channel is often stabilized against erosion by placing a protective lining over the soil.
Channel lining materials fall into two
