Bottomless Culvert Scour Study

COURSE NO: C04-032
PDH CREDIT: 4
Bottomless Culvert Scour Study
Course Highlights

This online engineering PDH course will present valuable information that can be used to perform a bottomless culvert scour study. The primary objective of this study was to validate or improve an existing methodology for estimating scour in bottomless culverts. The study included experiments to determine stability of rock riprap and to test effectiveness of rock cross vanes and other measures to reduce scour at the foundations of bottomless 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. 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 4 PDH online course is applicable to civil, geotechnical, structural, transportation and environmental engineers, as well as hydrologists, flood plain managers, land developers, and anyone with an interest in roadway hydraulics.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Understanding the types of cases where bottomless culverts could be used
  • Knowing the locations along the culvert where the deepest scour occurs
  • Understanding how to use Lauren's methods to determine the critical velocity
  • Understanding the effects of wingwalls on shear stress
  • Understanding the effects of cross vanes on scour
  • Knowing the characteristics of scour when considering unsubmerged and submerged flows
  • Learning about the alternatives to streamlined wingwalls
  • Learning how to reduce vortex shedding
